Regulation of the start of DNA replication in Schizosaccharomyces pombe. (1/2814)

Cells of Schizosaccharomyces pombe were grown in minimal medium with different nitrogen sources under steady-state conditions, with doubling times ranging from 2.5 to 14 hours. Flow cytometry and fluorescence microscopy confirmed earlier findings that at rapid growth rates, the G1 phase was short and cell separation occurred at the end of S phase. For some nitrogen sources, the growth rate was greatly decreased, the G1 phase occupied 30-50% of the cell cycle, and cell separation occurred in early G1. In contrast, other nitrogen sources supported low growth rates without any significant increase in G1 duration. The method described allows manipulation of the length of G1 and the relative cell cycle position of S phase in wild-type cells. Cell mass was measured by flow cytometry as scattered light and as protein-associated fluorescence. The extensions of G1 were not related to cell mass at entry into S phase. Our data do not support the hypothesis that the cells must reach a certain fixed, critical mass before entry into S. We suggest that cell mass at the G1/S transition point is variable and determined by a set of molecular parameters. In the present experiments, these parameters were influenced by the different nitrogen sources in a way that was independent of the actual growth rate.  (+info)

Temperature and pH conditions that prevail during fermentation of sausages are optimal for production of the antilisterial bacteriocin sakacin K. (2/2814)

Sakacin K is an antilisterial bacteriocin produced by Lactobacillus sake CTC 494, a strain isolated from Spanish dry fermented sausages. The biokinetics of cell growth and bacteriocin production of L. sake CTC 494 in vitro during laboratory fermentations were investigated by making use of MRS broth. The data obtained from the fermentations was used to set up a predictive model to describe the influence of the physical factors temperature and pH on microbial behavior. The model was validated successfully for all components. However, the specific bacteriocin production rate seemed to have an upper limit. Both cell growth and bacteriocin activity were very much influenced by changes in temperature and pH. The production of biomass was closely related to bacteriocin activity, indicating primary metabolite kinetics, but was not the only factor of importance. Acidity dramatically influenced both the production and the inactivation of sakacin K; the optimal pH for cell growth did not correspond to the pH for maximal sakacin K activity. Furthermore, cells grew well at 35 degrees C but no bacteriocin production could be detected at this temperature. L. sake CTC 494 shows special promise for implementation as a novel bacteriocin-producing sausage starter culture with antilisterial properties, considering the fact that the temperature and acidity conditions that prevail during the fermentation process of dry fermented sausages are optimal for the production of sakacin K.  (+info)

The role of benzoate in anaerobic degradation of terephthalate. (3/2814)

The effects of acetate, benzoate, and periods without substrate on the anaerobic degradation of terephthalate (1, 4-benzene-dicarboxylate) by a syntrophic methanogenic culture were studied. The culture had been enriched on terephthalate and was capable of benzoate degradation without a lag phase. When incubated with a mixture of benzoate and terephthalate, subsequent degradation with preference for benzoate was observed. Both benzoate and acetate inhibited the anaerobic degradation of terephthalate. The observed inhibition is partially irreversible, resulting in a decrease (or even a complete loss) of the terephthalate-degrading activity after complete degradation of benzoate or acetate. Irreversible inhibition was characteristic for terephthalate degradation only because the inhibition of benzoate degradation by acetate could well be described by reversible noncompetitive product inhibition. Terephthalate degradation was furthermore irreversibly inhibited by periods without substrate of only a few hours. The inhibition of terephthalate degradation due to periods without substrate could be overcome through incubation of the culture with a mixture of benzoate and terephthalate. In this case no influence of a period without substrate was observed. Based on these observations it is postulated that decarboxylation of terephthalate, resulting in the formation of benzoate, is strictly dependent on the concomitant fermentation of benzoate. In the presence of higher concentrations of benzoate, however, benzoate is the favored substrate over terephthalate, and the culture loses its ability to degrade terephthalate. In order to overcome the inhibition of terephthalate degradation by benzoate and acetate, a two-stage reactor system is suggested for the treatment of wastewater generated during terephthalic acid production.  (+info)

Citric acid production from xylan and xylan hydrolysate by semi-solid culture of Aspergillus niger. (4/2814)

Citric acid production from xylan and xylan hydrolysate was done by Aspergillus niger Yang no. 2 cultivated in a semi-solid culture using bagasse as a carrier. Yang no. 2 produced 72.4 g/l and 52.6 g/l of citric acid in 5 d from 140 g/l of xylose and arabinose, respectively. Yang no. 2 produced 51.6 g/l of citric acid in 3 d from a concentrated xylan hydrolysate prepared by cellulase treatment, containing 100 g/l of reducing sugars. Moreover, Yang no. 2 directly produced 39.6 g/l of citric acid maximally in 3 d from 140 g/l of xylan.  (+info)

High-rate anaerobic treatment of wastewater at low temperatures. (5/2814)

Anaerobic treatment of a volatile fatty acid (VFA) mixture was investigated under psychrophilic (3 to 8 degrees C) conditions in two laboratory-scale expanded granular sludge bed reactor stages in series. The reactor system was seeded with mesophilic methanogenic granular sludge and fed with a mixture of VFAs. Good removal of fatty acids was achieved in the two-stage system. Relative high levels of propionate were present in the effluent of the first stage, but propionate was efficiently removed in the second stage, where a low hydrogen partial pressure and a low acetate concentration were advantageous for propionate oxidation. The specific VFA-degrading activities of the sludge in each of the modules doubled during system operation for 150 days, indicating a good enrichment of methanogens and proton-reducing acetogenic bacteria at such low temperatures. The specific degradation rates of butyrate, propionate, and the VFA mixture amounted to 0.139, 0.110, and 0.214 g of chemical oxygen demand g of volatile suspended solids-1 day-1, respectively. The biomass which was obtained after 1.5 years still had a temperature optimum of between 30 and 40 degrees C.  (+info)

Tessaracoccus bendigoensis gen. nov., sp. nov., a gram-positive coccus occurring in regular packages or tetrads, isolated from activated sludge biomass. (6/2814)

An isolate of a Gram-positive bacterium, designated strain Ben 106T, was obtained in pure culture by micromanipulation of a biomass sample obtained from a laboratory-scale sequencing batch reactor. This isolate grew axenically as cocci or clusters of cocci arranged in regular tetrads and was morphologically similar to the dominant organism observed in the biomass. This morphology resembled that of some Gram-positive and -negative bacteria and the so-called 'G-bacteria' commonly seen in activated sludge samples. Strain Ben 106T is a non-motile, facultative anaerobe. It is oxidase-negative, catalase-positive and is capable of reducing nitrate. This organism can grow between 20 and 37 degrees C, with an optimum temperature of 25 degrees C. The pH range for growth is between 6.0 and 9.0, with an optimum pH of 7.5. The isolate stained positively for intracellular polyphosphate granules. The diagnostic diamino acid of the peptidoglycan is LL-diaminopimelic acid (LL-A2pm) with a glycine moiety at position 1 of the peptide subunit, which characterizes the presence of a rare peptidoglycan (type A3-gamma'). Two menaquinones, MK-9(H4) and MK-7(H4), are present and the main cellular fatty acid is 12-methyltetradecanoic acid. The G + C content is 74 mol%. From phenotypic characteristics and 16S rDNA sequence analysis, the isolate differed sufficiently from its closest phylogenetic relatives, namely Propionibacterium propionicum, Propioniferax innocua, Friedmanniella antarctica, Luteococcus japonicus and Microlunatus phosphovorus in the A1 subdivision of the Gram-positive bacteria (i.e. Firmicutes with a high G + C content), suborder Propionibacterineae, to be placed in a new genus, Tessaracoccus, as Tessaracoccus bendigoensis gen. nov., sp. nov. The type strain is Ben 106T (= ACM 5119T).  (+info)

Carbon and electron flow in Clostridium cellulolyticum grown in chemostat culture on synthetic medium. (7/2814)

Previous results indicated poor sugar consumption and early inhibition of metabolism and growth when Clostridium cellulolyticum was cultured on medium containing cellobiose and yeast extract. Changing from complex medium to a synthetic medium had a strong effect on (i) the specific cellobiose consumption, which was increased threefold; and (ii) the electron flow, since the NADH/NAD+ ratios ranged from 0.29 to 2.08 on synthetic medium whereas ratios as high as 42 to 57 on complex medium were observed. These data indicate a better control of the carbon flow on mineral salts medium than on complex medium. By continuous culture, it was shown that the electron flow from glycolysis was balanced by the production of hydrogen gas, ethanol, and lactate. At low levels of carbon flow, pyruvate was preferentially cleaved to acetate and ethanol, enabling the bacteria to maximize ATP formation. A high catabolic rate led to pyruvate overflow and to increased ethanol and lactate production. In vitro, glyceraldehyde-3-phosphate dehydrogenase, lactate dehydrogenase, and ethanol dehydrogenase levels were higher under conditions giving higher in vivo specific production rates. Redox balance is essentially maintained by NADH-ferredoxin reductase-hydrogenase at low levels of carbon flow and by ethanol dehydrogenase and lactate dehydrogenase at high levels of carbon flow. The same maximum growth rate (0.150 h-1) was found in both mineral salts and complex media, proving that the uptake of nutrients or the generation of biosynthetic precursors occurred faster than their utilization. On synthetic medium, cellobiose carbon was converted into cell mass and catabolized to produce ATP, while on complex medium, it served mainly as an energy supply and, if present in excess, led to an accumulation of intracellular metabolites as demonstrated for NADH. Cells grown on synthetic medium and at high levels of carbon flow were able to induce regulatory responses such as the production of ethanol and lactate dehydrogenase.  (+info)

Differentiation of Helicobacter pylori isolates based on lectin binding of cell extracts in an agglutination assay. (8/2814)

Plant and animal lectins with various carbohydrate specificities were used to type 35 Irish clinical isolates of Helicobacter pylori and the type strain NCTC 11637 in a microtiter plate assay. Initially, a panel of eight lectins with the indicated primary specificities were used: Anguilla anguilla (AAA), Lotus tetragonolobus (Lotus A), and Ulex europaeus I (UEA I), specific for alpha-L-fucose; Solanum tuberosum (STA) and Triticum vulgaris (WGA), specific for beta-N-acetylglucosamine; Glycine max (SBA), specific for beta-N-acetylgalactosamine; Erythrina cristagali (ECA), specific for beta-galactose and beta-N-acetylgalactosamine; and Lens culinaris (LCA), specific for alpha-mannose and alpha-glucose. Three of the lectins (SBA, STA, and LCA) were not useful in aiding in strain discrimination. An optimized panel of five lectins (AAA, ECA, Lotus A, UEA I, and WGA) grouped all 36 strains tested into eight lectin reaction patterns. For optimal typing, pretreatment by washing bacteria with a low-pH buffer to allow protein release, followed by proteolytic degradation to eliminate autoagglutination, was used. Lectin types of treated samples were stable and reproducible. No strain proved to be untypeable by this system. Electrophoretic and immunoblotting analyses of lipopolysaccharides (LPSs) indicated that the lectins interact primarily, but not solely, with the O side chain of H. pylori LPS.  (+info)

In order to better assess the spatial variability in subtropical forest biomass, the goal of our study was to use small-footprint, discrete-return Light Detection and Ranging (LiDAR) data to accurately estimate and map above- and below-ground biomass components of subtropical forests. Foliage, branch, trunk, root, above-ground and total biomass of 53 plots (30 × 30 m) were modeled using a range of LiDAR-derived metrics, with individual models built for each of the three dominant forest types using stepwise multi-regression analysis. A regular grid covered the entire study site with cell size 30 × 30 m corresponding to the same size of the plots; it was generated for mapping each biomass component. Overall, results indicate that biomass estimation was more accurate in coniferous forests, compared with the mixed and broadleaved plots. The coefficient of determination (R2) for individual models was significantly enhanced compared with an overall generic, or common, model. Using independent stand-level
The potential of a plant species to acquire nutrients depends on its ability to explore the soil by its root system. Co-cultivation of different species is anticipated to lead to vertical root niche differentiation and thus to higher soil nutrient depletion. Using a qPCR-based method we quantified root biomass distribution of four catch crop species in vertical soil profiles in pure vs. mixed stands. Pure stands of mustard and phacelia robustly reached 70 cm soil depth, while oat preferably colonized upper soil layers, and clover developed the shallowest and smallest root system. Analysis of residual nitrate pools in different soil depths and correlation with root biomass showed that, besides rooting depth also root biomass determines soil nitrogen depletion. While occupying the same vertical niches as in pure stands, mustard and phacelia dominated total root biomass of the mix. In contrast, root biomass of clover and oat was severely suppressed in presence of the other species. Below-ground biomass
ORNL DAAC: This data set provides a single raster image containing the spatial distribution of aboveground live forest biomass of the Amazon basin. This product was derived using a methodology based on a combination of land cover map, remote sensing derived metrics, and more than 500 forest plots distributed over the basin (Saatchi, et al., 2007). The distributed map was produced in ENVI, in Tiff format and it contains forest biomass divided among 11 classes at 1 km spatial resolution with reasonable accuracy (better than 70%). Remote sensing and ground data used in this product were collected from 1990-2000. The Biomass map represents average biomass distribution over the Amazon basin over this period and was used to estimate the total carbon stock of the basin, including the dead and belowground biomass.
Woody biomass is one of the most abundant biomass feedstocks, besides agriculture residuals in the United States. The sustainable harvest residuals and thinnings alone are estimated at about 75 million tons/year. These forest residuals and thinnings could produce the equivalent of 5 billion gallons of lignocellulosic ethanol annually. Softwood biomass is the most recalcitrant biomass in pretreatment before an enzymatic hydrolysis. To utilize the most recalcitrant lignocellulosic materials, an efficient, industrially scalable and cost effective pretreatment method is needed. Obtaining a high yield of sugar from recalcitrant biomass generally requires a high severity of pretreatment with aggressive chemistry, followed by extensive conditioning, and large doses of enzymes. Catchlight Energys Sugar process, CLE Sugar, uses a low intensity, high throughput variation of bisulfite pulping to pretreat recalcitrant biomass, such as softwood forest residuals. By leveraging well-proven bisulfite technology and
Long-term heavy grazing had little effect on root and crown biomass of Indian ricegrass (Oryzopsis hymenoides), nor did it significantly affect the total nonstructural carbohydrate (TNC) reserve levels or the seasonal cycle of reserves in this grass. Orodho and Trlica conclude that 50 years of protection from livestock use had not resulted in ecotypic differentiation in Indian ricegrass for these variables. Clipping reduced crown biomass more than root biomass and removal of 90% of aboveground biomass resulted in more than a 50% reduction in crown biomass and reserve carbohydrate pool. In a garden study that compared the native Chaco Canyon strains to two commercial strains of Indian ricegrass (Nezpar and Paloma), the Nezpar strain was superior to Paloma and the Chaco Canyon strains in production of crown biomass and TNC reserves at the more mesic garden site. The native strains from the more arid Chaco Canyon were superior to both cultivated strains in root production, and the native
In Finland it is estimated that forest biomass will be the main source of bioenergy when meeting the national target: 38% renewable from total energy consumption by 2020. This target must become concrete for regional and local level participators of a forest industry and actions should take place in large combined heat and power generation (CHP) plants, district heating plants and independent heating systems. In energy production replacing fossil fuels with renewa-ble energy is reasonable in many cases. However, there are usually doubts about the availability and security of supply of forest biomass. The aim of this study is to introduce a systematical method for analyzing the availability and demand of forest biomass in regional and local level. This study introduces an objective method for analyzing local possibilities on where and how much the use of forest biomass could be increased. By replacing use of fossil fuels with renewable and domestic energy sources carbon dioxide (CO2) emissions and

The global issue of climate change and an increasing interest in the reduction of fossil fuel carbon dioxide emissions by using forest biomass for energy production has increased the importance of forest biomass quantification in recent years. Different national and international reports have presented the amount of carbon sequestered by forest ecosystems. For example, the Intergovernmental Panel on Climate Change reports that forests contain about 80% of aboveground and 40% of belowground carbon stock (IPCC 2007). Additionally, it is reported that the amount of carbon stored in dry wood is approximately 50% by weight (Brown 1986; Paladinic et al. 2009; Sedjo and Sohngen 2012).. Biomass, in general, includes both above and below ground living and dead mass of trees, shrubs, vines, and roots. However, most of the researches on biomass estimation have focused on aboveground biomass because of the difficulty in collecting belowground data (Lu 2006). The amount of biomass in a forest is influenced ...
ORNL DAAC: This dataset provides maps of aboveground tidal marsh biomass (g/m2) at 30 m resolution for six estuarine regions of the conterminous United States: Cape Cod, MA; Chesapeake Bay, MD, Everglades, FL; Mississippi Delta, LA; San Francisco Bay, CA; and Puget Sound, WA. Estuarine and palustrine emergent tidal marsh areas were based on a 2010 NOAA Coastal Change Analysis Program (C-CAP) map. Aboveground biomass maps were generated from a random forest model driven by Landsat vegetation indices and a national scale dataset of field-measured aboveground biomass. The final model, driven by six Landsat vegetation indices, with the soil adjusted vegetation index as the most important, successfully predicted biomass for a range of marsh plant functional types defined by height, leaf angle, and growth form. Biomass can be converted to carbon stocks using a mean plant carbon content of 44.1%.

Among other ...
Downloadable! This study introduces a framework for modeling a renewable forest biomass stock interacting with economic sectors in a competitive economy. The equilibrium is formulated as a mixed complementary problem (which explicitly represents weak inequalities and complementary among decision variables and equilibrium conditions). The complementarity format permits detailed modeling of the growth and harvest of a biomass stock together with a second-best characterization of the overall economy. First the complementarity features of economic equilibrium and its integration with an ecological representation of the biomass are provided. Then a stylized numerical example of a dynamic computable general equilibrium model is presented. Finally, illustrative applications of the model for gauging the likely effects of environmental subsidies and taxes intended to promote increases CO2 storage in forest biomass are given, the results are discussed.

A biomass hydrothermal decomposition apparatus includes, a biomass feeder ( 31 ) that feeds biomass material ( 11 ) under normal pressure to under increased pressure, a hydrothermal decomposition device ( 42 A) that allows the fed biomass material ( 11 ) to be gradually moved inside a device main body ( 42 A) from either end thereof in a consolidated condition, and also allows hot compressed water ( 15 ) to be fed from an other end of a feed section for the biomass material into the main body ( 42 A), so as to cause the biomass material ( 11 ) and the hot compressed water ( 15 ) to countercurrently contact with each other and undergo hydrothermal decomposition, and that elutes a lignin component and a hemicellulose component into the hot compressed water, so as to separate the lignin component and the hemicellulose component from the biomass material ( 11 ); and a biomass discharger ( 51 ) that discharges, from the side where the hot compressed water is fed into the device main body, a biomass
Tracer experiments are of concern to wastewater treatment engineers and researchers because of the importance of determining hydraulic regimes and retention times in wastewater treatment units. In this work, a pilot-scale maturation waste stabilisation pond (WSP) was spiked with Rhodamine WT, in order to determine how suspended organic matter would interfere with its performance as a tracer in a domestic wastewater treatment unit which had a high content of suspended algal biomass. A primary maturation pond was spiked in three separate runs with different levels of algae (high, medium and low), with a known amount of Rhodamine WT (20% v/v); the tracer was measured in the pond effluent in real time every 20 min for 3θ (the theoretical retention time, θ = 17 d). Algal biomass was monitored weekly from influent, column and effluent water samples by chlorophyll-a determination. The results show that algal biomass has a strong influence on the behaviour of Rhodamine WT as a tracer and therefore the ...
As an alternative renewable source for bioenergy, forest biomass has recently drawn more attention from the U.S. government and the general public. Woody biomass policies have been adopted to encourage the new bioenergy industry. A variety of state policy incentives attempt to create a desirable legal climate and lure new firms, imposing two important questions regarding state government policies and the sustainable use of forest resources. This dissertation sheds some light on these questions. The first paper constructs a woody biomass policy index through scoring each statute and weighting different categories of policies from the vantage point of renewable energy investment. It analyzes the disparity in the strength of state government incentives in the woody biomass utilization. The second paper employs a conditional logit model (CLM) to explore the effects of woody biomass policies on the siting decisions of new bioenergy projects. In addition, significant state attributes influencing the
The data and analyses presented support the research article entitled Coupling partial-equilibrium and dynamic biogenic carbon models to assess future transport scenarios in France (Albers et al., 2019). Carbon sequestration and storage in forestry products (e.g. transport fuels) is sought as a climate change mitigation option. The data presented support and inform dynamic modelling approaches to predict biomass growth and carbon fixation dynamics , of a tree or forest stand, over specific rotation lengths. Data consists of species-specific yield tables, parameters for non-linear growth models and allometric equations. Non-linear growth models and allometric equations are listed and described. National statistics and surveys of the wood supply chain serve to identify main tree species, standing wood volumes and distributions within specific geographies; here corresponding to managed forests in France. All necessary data and methods for the computation of the annual fixation flows are presented.
Gene expression is regulated through a complex interplay of different transcription factors (TFs) which can enhance or inhibit gene transcription. ArcA is a global regulator that regulates genes involved in different metabolic pathways, while IclR as a local regulator, controls the transcription of the glyoxylate pathway genes of the aceBAK operon. This study investigates the physiological and metabolic consequences of arcA and iclR deletions on E. coli K12 MG1655 under glucose abundant and limiting conditions and compares the results with the metabolic characteristics of E. coli BL21 (DE3). The deletion of arcA and iclR results in an increase in the biomass yield both under glucose abundant and limiting conditions, approaching the maximum theoretical yield of 0.65 c-mole/c-mole glucose under glucose abundant conditions. This can be explained by the lower flux through several CO2 producing pathways in the E. coli K12 ΔarcAΔiclR double knockout strain. Due to iclR gene deletion, the glyoxylate pathway
We examined the effects of N fertilization on forest soil fungal and bacterial biomass at three long-term experiments in New England (Harvard Forest, MA; Mt. Ascutney, VT; Bear Brook, ME). At Harvard Forest, chronic N fertilization has decreased organic soil microbial biomass C (MBC) by an average of 54% and substrate induced respiration (SIR) was decreased by an average of 45% in hardwood stands. In the pine stand, organic soil MBC was decreased by 40% and SIR decreased by an average of 35%. The fungal:bacterial activity ratio was also decreased in the hardwood stands from an average of 1.5 in the control plot to I .O in the High-N plot, and in the pine stands from 1.9 in control plot to 1.0 in the High-N stand. At Mt. Ascutney, MBC was reduced by an average of 59% and SIR by 52% in the High N plots relative to the unfertilized plots, and the fungal:bacterial activity ratio was only slightly decreased. The Bear Brook watershed is in an earlier stage of N saturation (Stage 0-1) and did not ...
The miombo woodland is the most extensive dry forest in the world, with the potential to store substantial amounts of biomass carbon. Efforts to obtain accurate estimates of carbon stocks in the miombo woodlands are limited by a general lack of biomass estimation models (BEMs). This study aimed to evaluate the accuracy of most commonly employed allometric models for estimating aboveground biomass (AGB) in miombo woodlands, and to develop new models that enable more accurate estimation of biomass in the miombo woodlands. A generalizable mixed-species allometric model was developed from 88 trees belonging to 33 species ranging in diameter at breast height (DBH) from 5 to 105 cm using Bayesian estimation. A power law model with DBH alone performed better than both a polynomial model with DBH and the square of DBH, and models including height and crown area as additional variables along with DBH. The accuracy of estimates from published models varied across different sites and trees of different diameter

Caldicellulosiruptor glycoside hydrolase inventory.As mentioned above, only two (C. bescii and C. saccharolyticus) of the nine described Caldicellulosiruptor species currently have publically available genome sequences (29, 51). Due to renewed interest in biomass-degrading microbes, five additional genome sequencing projects are under way, three of which are finished (for C. hydrothermalis, C. kronotsyensis, and C. owensensis), to help pinpoint what makes some species more cellulolytic than others in the genus. Draft and finished versions of these genome sequences were examined for GH family diversity.. Previous studies looking into Caldicellulosiruptor diversity have identified glycoside hydrolases, mostly cellulases and xylanases, produced by selected species (4, 19). Here, the biomass deconstruction-related GH inventory, inferred from each draft and finished genome sequence, was examined to provide insights into the observed differential responses to microcrystalline cellulose. Based on the ...

Grasses such as Miscanthus ×giganteus and Panicum virgatum (switchgrass) can potentially be used to produce bioenergy on a large scale in the Midwestern USA. The biomass productivity of these warm-season perennial grasses, particularly M. × giganteus, can be substantial, even when grown with limited inputs. The literature, however, varies regarding the nitrogen requirements for M. ×giganteus biomass production. In addition, there is a lack of information that identifies the yield-component(s) (including total tiller number, tiller weight, total tiller diameter, total tiller height, phytomer number, reproductive tiller number, vegetative tiller number, reproductive tiller height, vegetative tiller height, reproductive tiller diameter, vegetative tiller diameter, and reproductive tiller phytomer number) that contributes to M. ×giganteus biomass yields. Thus, the objective of this study was to examine the effects of fertilization on biomass yield and individual M. × giganteus plant-yield components.
Abstract: The micro alga, Spirulina is a rich source of protein, which is used as a protein supplement for humans, chicks and also in aquaculture. Among the cultures, CS-1 registered maximum biomass production and S-20 showed highest biomass production among the local isolates. Optimum temperature of 35°C was the best for maximum biomass production of S. platensis cultures. Among the cultures CS-1 culture, put forth maximum biomass production at 35°C. The biomass production of all S. platensis cultures was maximum at pH 10.0. Among the cultures, CS-1 recorded maximum biomass at pH 10.0. S. platensis culture S-20 showed highest biomass production among the local isolates. S. platensis cultures were grown under different light wave lengths ranging from 340-700 nm and observed that it grows best in red light but later on there was no significant difference between the biomass produced under red and normal white lights. S. platensis culture CS-1 has shown the highest chlorophyll, carotenoids and ...
These early forest biomass studies were aimed at major or typical forest types, with developed biomass models largely based on stand or sample plot levels. Some biomass models were even based on individual tree data, most of them suited only for certain sites or local areas, not representative of larger regions. These forest carbon assessments were based on estimates of biomass per hectare for our major forest types from purposeful sampling and areas of forest types from our national forest inventory, which is not really suited for monitoring and assessing forest carbon storage.. The International Guidelines for Forest Monitoring, published by IUFRO ([1994]), clearly defined forest biomass as one of the important items of global, regional and national forest monitoring. In order to add forest biomass into the items of national forest inventory of China, the Ministry of Forestry conducted a key program Research on two-variable biomass models and compatible auto-adoptive one-variable biomass ...
where nitrogen and phosphorus concentrations were at its maximum level (+1). On the other hand, with treatments 9 (N0) and 11 (P0), the lowest AFDW, 0.80 and 0.62 g∙L−1, respectively, were obtained. Therewith, the maximum biomass value obtained was 2.3 times higher than the reports of [1] , which reported a biomass concentration of 0.54 g∙L−1 when cultivating Scenedesmus obliquus with ambient CO2, and when cultivated at 35% of CO2 supply, it was reported a maximum biomass value of 1.39 g∙L−1. The maximum biomass of 1.24 g∙L−1 obtained with the Scenedesmus sp. SCIB-01 strain, without CO2 supply, was comparable to reports of [3] who obtained biomass concentration of 1.34 g∙L−1 using S. obliquus cultivated at 2.5% CO2 feeding concentration. [8] reported S. obliquus cultivation at 30% CO2 concentration, and obtained a biomass concentration of 1.03 g∙L−1. [18] obtained a maximum biomass production of 0.41 g∙L−1 using Desmodesmus sp. phototrophically cultivated, also lower ...

Biomass had so much promise. But now its about to go up in smoke. Only a few years ago, energy production from biomass had one of the brightest, most promising futures in both the US and Europe. The EUs 20/20/20 Renewable Energy Directive set a sizable proportion of the 20% renewable energy goal to come from biomass. It looked like biomass was the perfect answer to the renewable energy puzzle. The problem no one anticipated was the smoke.. The trouble for biomass as a public energy source, as opposed to an industrial fuel, started in Massachusetts. In 2010, under then-Governor Deval Patrick, biomass was to become a key component of the states renewable energy policy, and it seemed like a slam-dunk. But then public opinion started asking about the smoke. The prevailing wisdom at the time was that biomass was carbon neutral, which meant that burning wood would add no more carbon dioxide, a known greenhouse gas, to the atmosphere than could be reabsorbed.. What would become known as the ...
Water stress and nutrient deficiency are considered to be the main environmental factors limiting plant growth and species interaction in semiarid regions. However, less is known about the interactive effects of soil water, nitrogen and phosphorus on native species growth and relative competitive ability. A replacement series design method was used with 12 mixed plants of Bothriochloa ischaemum and Lespedeza davurica grown in a pot experiment under three water regimes and four fertility treatments. Intercropping systems were assessed on the basis of indices such as biomass production and allocation, relative competitive ability, aggressivity, relative yield total and water use efficiency (WUE). Water stress decreased significantly the total biomass production for each species, either in monoculture or in mixtures. N, P, or NP application can significantly improve biomass production of the two species in their mixtures. There was no obvious change trend in root/shoot ratio of B. ischaemum or L. davurica
In order to protect the city of New Orleans from the Mississippi River flooding, the Bonnet Carré Spillway (BCS) was constructed from 1929 to 1936 to divert flood water from the river into Lake Pontchartrain and then into the Gulf of Mexico. During the BCS opening for flood release, large amounts of freshwater, nutrients, sediment, etc. were discharged into Lake Pontchartrain, and caused a lot of environmental problems. To evaluate the environmental impacts of the flood water on lake ecosystems, a two-dimensional numerical model was developed based on CCHE2D and applied to simulate the flow circulation, sediment transport and algal biomass distribution in Lake Pontchartrain. The effect of sediment concentration on the growth of algae was considered in the model. The numerical model was calibrated using field measured data provided by USGS, and then it was validated by the BCS Opening Event in 1997. The simulated results were generally in good agreement with filed data and satellite imagery
A batch nitrification process was studied using synthetic wastewater as substrate and Chilean natural zeolite as biomass carrier at ambient temperatures (20 °C). Three groups of experiments were carried out: a first experimental set (I) with and without added zeolite using initial biomass concentrations of 1,000 and 2,000 mg VSS/ L; a second set of experiments (II) with added zeolite and at the same initial biomass concentrations. In these two experimental sets, biomass from an activated sludge process located in an urban wastewater treatment plant at La Farfana, Santiago de Chile, was used as inoculum (1). Finally, a third set of experiments (III) was carried out with zeolite at an initial biomass concentration of 1,000 mg VSS/L using an inoculum derived from an activated sludge process treating wastewater from a paper mill (inoculum 2). Nitrifying biomass concentration values in the range of 13,000-18,800 mg VSS/L were achieved when initial biomass concentrations varied between 1,000 and ...
Keywords: Gross N biotransformation, soil microbial biomass, nitrogen availability, mineralisation, C:N ratios.. Summary:. Understanding the factors that govern microbial activities in soils is important, because the heterotrophic soil microbial biomass is driving the carbon (C) and nitrogen (N) cycling, and the net availability of N for plant uptake or losses. The processes by which C and N interact during decomposition of organic matter in soil, and the mineralisation-immobilisation turnover are well known but still difficult to predict, due to the complex interactions between soil micro-organisms and their substrates. The 15N isotope dilution techniques that allow rates of N transformations to be quantified accurately and simultaneously help the understanding of the effects of soil, crop and management conditions on microbial activities. The quantification of the relative importance of gross mineralisation, immobilisation and nitrification is also a key for understanding the competition ...

The microbial biomass consists mostly of bacteria and fungi, which decompose crop residues and organic matter in soil. This process releases nutrients, such as nitrogen (N), into the soil that are available for plant uptake. About half the microbial biomass is located in the surface 10 cm of a soil profile and most of the nutrient release also occurs here. Generally, up to 5% of the total organic carbon and N in soil is contained in the microbial biomass at any one time. When microorganisms die, these nutrients are released in forms that can be taken up by plants.. ...
p,Zooplankton play an important role in the trophic dynamics of coral reef ecosystems. Detailed vertical and temporal distribution and biomass of zooplankton were evaluated at four heights off the bottom and at six times throughout the diel cycle over a coral reef in the Florida Keys (USA). Zooplankton abundance averaged 4396 +/- 1949 SD individuals m(-3), but temporal and spatial distributions varied for individual zooplankton taxa by time of day and by height off the bottom. Copepods comprised 93-96% of the abundance in the samples. Taxon-based zooplankton CHN values paired with abundance data were used to estimate biomass. Average daily biomass ranged from 3.1 to 21.4 mg C m(-3) and differed by both height off the bottom and by time of day. While copepods were the numerically dominant organisms, their contribution to biomass was only 35% of the total zooplankton biomass. Our findings provide important support for the new emerging paradigm of how zooplankton are distributed over ...
The advantages of newly developed high biomass sorghum and pearl millet developed by ICRISAT and Indian Institute of Millets Research (IIMR) for use as feedstock in second generation or lignocellulosic (2G) biofuel production in India was highlighted at a recent workshop.. The advantageous traits of these dryland crops are wider adaptability, fast growth, high biomass production potential, resilience to drought, and non-compromise on food security as the grain is used for human consumption. The use of these crops in biofuel production has the potential of improving incomes of Indian farmers in the semi-arid regions.. India is a signatory to the UN Climate Change Paris Agreement (COP21) and biofuel production is one of the thrust areas identified to reduce greenhouse gas emissions. The countrys ethanol production is mainly from sugarcane molasses. However, considering severe water shortages there is limited scope to increase the production of this water-intensive crop. Hence there is a need to ...

Biomass is used worldwide 1 minute-3 minutes The best locations that allow biomass are farm areas. This is because on a farm you can find various aspects that are used to create biomass. For starters you have all the plants and crops, for example hay, dried corn, tall grass, ect. Also, you would find multiple animals whose manure could be turned into biomass, for example cows, horses, pigs, ect. Then you have wood chips from some of the animal pens, along with all of the trash the people produce. But most of all, you find all of these things, which make biomass, in one location. Science is applied to everything in biomass. To start off, people had to experiment a lot, and discover how to make biomass into a renewable resource. Then comes the machinery used to actually create the biomass. People had to find and build the right machines that are used throughout the entire process. Next, science comes in when it comes to the wood, plants, manure, waste, and garbage that goes into biomass. The ...
Influence of Urea Formaldehyde Resin on the Pyrolysis of Biomass Components: Cellulose, Hemicellulose, and Lignin. Zongyuan Lai, Sijin Li, Yu Zhang, Yushuang Li, and Jun Mu *. Wood-based panels, which are often used and then abandoned, are a potential resource for energy recovery. To better understand the pyrolysis of wood-based panels, the effect of urea formaldehyde (UF) resin on the pyrolysis of the wood components (cellulose, hemicellulose, and lignin) was investigated. Thermogravimetric analysis (TGA), gas chromatography coupled with mass spectrometry (GC-MS), and an ultimate analysis were used to investigate the pyrolysis process and products of the biomass components mixed with 10% UF resin. The UF resin specifically inhibited the decomposition rate of cellulose and promoted the thermal decomposition of lignin. For xylan, the UF resin had little impact. The UF resin mainly affected the mass loss of C and O. Loss of both elements in lignin was promoted, but only C loss increased in ...

Biomass (conventional and non-conventional) fuels co-fired with coal for power and steam generation are being tested and evaluated at several generation stations in the United States. The co-firing technology is expected to reduce landfill requirements for biomass wastes, and to provide a renewable, low pollution and zero net carbon dioxide fuel. The choice of the biomass depends upon local availability and cost of the transportation. The renewable biomass fuels range from agro to animal waste based fuels. For coal fired power plants located around feedlots where cattle are raised, the renewable biomass is the cattle manure, called feedlot biomass (FB). Thus coal could be mixed with feedlot biomass and then fired in existing boiler burners. A 30 KW (100,000 Btu/hr) boiler burner facility was built at Texas A&M University Boiler Burner Laboratory and the burner was fired with coal or coal-FB blends. Most of the previous data concerned with coal performance results from co-firing of low moisture ...
The objective of this study was to investigate the impact of bacterial biomass on the sorption and transport of three solutes (quinoline, naphthalene, and 45Ca) in a subsurface soil. Miscible displacement techniques were employed to measure sorption and transport of the above compounds during steady, saturated water flow in sterile and/or bacterium-inoculated soil columns. The soil was inoculated with either a quinoline-degrading bacterium, Pseudomonas sp. 3N3A isolate, or its mutant isolate, B53, which does not degrade quinoline. In soil columns inoculated with the B53 and 3N3A isolates, quinoline sorption was reduced by about 60 and 20%, respectively. In contrast, 45Ca sorption was minimally reduced, which indicated that biomass did not significantly alter the cation-exchange capacity of the soil. Biomass impacts on sorption were solute specific, even when the sorption mechanism for both quinoline and 45Ca was similar. Thus, the differential response is attributed to biomass-induced changes in ...

Abstract: 1. Nutrient additions typically increase terrestrial ecosystem productivity, reduce plant diversity and alter plant community composition; however, the effects of P additions and interactions between N and P are understudied. 2. We added both N (10 g m-2) and three levels of P (2.5, 5 and 10 g m-2) to a native, ungrazed tallgrass prairie burned biennially in northeastern Kansas, USA, to determine the independent and interactive effects of N and P on plant community composition and above-ground net primary productivity (ANPP). 3. After a decade of nutrient additions, we found few effects of P alone on plant community composition, N alone had stronger effects, and N and P additions combined resulted in much larger effects than either alone. The changes in the plant community were driven by decreased abundance of C4 grasses, perhaps in response to altered interactions with mycorrhizal fungi, concurrent with increased abundance of non-N-fixing perennial and annual forbs. Surprisingly, this ...
Four European exotic earthworm fronts, two in Minnesota and two in Wisconsin, were used to examine the effect of earthworm guild assemblages (treatments) on the composition of the bacterial and fungal communities. Four transects, each containing 5 treatments based on ecological guild dominance (epigeic, endogeic, anecic, anecic 50 m, anecic 100 m) were constructed perpendicular to four advancing exotic earthworm fronts. The activity of each dominating guild was confirmed by a continual decrease in the O horizon depth and subsequent increase in A horizon depth. Soil samples collected in the fall of 2013 were used to examine the effect of guild assemblages on the soil microbial community. No biological differences were observed in microbial biomass carbon (MBC), microbial biomass nitrogen (MBN), MBC: MBN, and carbon substrate utilization using Biolog Eco- and FF plates. TRFLP community profiles indicated the bacterial communities among treatments were highly similar, but a partial shift in the ...
Do you need a new roof? Are you building a house and considering your roofing options? Many people assume that their options are limited; you either install shingles or a metal roof. The truth is there are many choices, including biomass roofing. What is Biomass Roofing? Biomass means that its made from natural materials. A great example, and a traditional one, is the thatch roof. Thatched roofs have been used for thousands of years. Traditionally theyre made from leaves, grasses, reeds, and straw. Of course todays thatch options are a bit more sophisticated. The Benefits of Biomass Roofing Biomass roofing options are incredibly durable. In fact thatch roofs are said to last between 50 and 70 years. Thats significantly longer than traditional shingles. Biomass is often a fantastic insulator. They are also made from materials that are renewable, and when you have to replace your roof you dont have to worry about filling up a landfill. Biomass is biodegradable. Biomass is also abundant and

EN] Potato plants were grown in open-top chambers under three ozone concentrations during two complete cropping seasons (93 and 77 d in 2004 and 2005, respectively). The effects of chronic exposure to ozone on leaf anatomy, cell ultrastructure and crop yield were studied. Severe cell damage was found, even at ambient ozone levels, mainly affecting the spongy parenchyma and areas near the stomata. Damage to the cell wall caused loss of cell contact, and loss of turgor pressure due to tonoplast disintegration, contributed to cell collapse. Phloem sieve plates were obstructed by callose accumulation, and damaged mesophyll cells increased their starch stores. Tuber yield fell sharply (24-44%), due to the biggest tubers becoming smaller, which affected commercial yield. These anatomical findings show the mechanisms of ozone effect on assimilate partitioning, and thus crop yield decrease, in potato. Further implications of ozone causing reductions in belowground biomass are also discussed ...
We investigated the presence, density and bacterial composition of contraceptive vaginal ring biomass and its association with the vaginal microbiome. Of 415 rings worn by 120 Rwandese women for three weeks, the biomass density was assessed with crystal violet and the bacterial composition of biomass eluates was assessed with quantitative polymerase chain reaction (qPCR). The biomass was visualised after fluorescence in situ hybridisation (FISH) and with scanning electron microscopy (SEM). The vaginal microbiome was assessed with Nugent scoring and vaginal biofilm was visualised after FISH. All vaginal rings were covered with biomass (mean optical density (OD) of 3.36; standard deviation (SD) 0.64). Lactobacilli were present on 93% of the rings, Gardnerella vaginalis on 57%, and Atopobium vaginae on 37%. The ring biomass density was associated with the concentration of A. vaginae (OD +0.03; 95% confidence interval (CI) 0.01-0.05 for one log increase; p = 0.002) and of G. vaginalis (OD +0.03; (95% CI 0

Altered wind conditions and light climate lead to a general change in the microclimate at the forest edges. Big old trees are particularly vulnerable to these factors. With the help of FORMIND, a forest simulation software developed at the UFZ, the researchers modelled different sizes of forest patches left over after landscape fragmentation. The smaller a patch of forest is, the worse is the ratio between edge and area. Simulation results suggest that a natural tropical forest of our study area contained approximately 250 tonnes of aboveground biomass per hectare, a forest fragment measuring 100 hectares has around 228 tonnes of biomass per hectare, while a patch of rain forest measuring one hectare has only 140 tonnes of biomass per hectare. In other words, the biomass in the forest remnants in this study fell by as much as 40 per cent. This finding is of great significance for the function of rain forests as a biomass store. It is important to be clear about the fact that we are losing more ...
Dielectric spectroscopy (DS) is routinely used in yeast and mammalian fermentations to quantitatively monitor viable biomass through the inherent capacitance of live cells: however, the use of DS to monitor the enzymatic break down of lignocellulosic biomass has not been reported. The aim of the current study was to examine the application of DS in monitoring the enzymatic saccharification of high sugar perennial ryegrass (HS-PRG) fibre and to relate the data to changes in chemical composition. DS was capable of both monitoring the on-line decrease in PRG fibre capacitance (C = 580 kHz) during enzymatic hydrolysis, together with the subsequent increase in conductivity (G = 580 kHz) resulting from the production of organic acids during microbial growth. Analysis of the fibre fractions revealed ,50% of HS-PRG lignocellulose had undergone enzymatic hydrolysis. These data demonstrated the utility of DS biomass probes for on-line monitoring of simultaneous saccharification and fermentation (SSF). (C) ...
The very nature of lignocellulosic biomass presents resistance and recalcitrance to biological and chemical degradation during enzymatic hydrolysis and the subsequent fermentation process. This leads to a very low conversion rate, which makes the process economically unfeasible. In this study, alkaline (NaOH) pretreatment was applied on barley straw, using radio-frequency-based dielectric heating to enhance accessibility and digestibility during the subsequent stage of enzymatic hydrolysis. Three levels of temperature (70, 80, and 90°C), five levels of biomass:NaOH solution ratio (1:4, 1:5, 1:6, 1:7, and 1:8), 1h equilibration time, screen size of 1.6mm, 1%w/v NaOH concentration, and 20min residence time were used for the pretreatment. The effect of the alkaline pretreatment was evaluated through chemical composition analysis of the pretreated and non-treated biomass samples. The use of NaOH solution and the biomass:NaOH solution ratio played a vital role in the breakdown of the lignified ...
This study aimed to assess the effects of biomass smoke exposure on lung function in a Nepalese population, addressing some of the methodological issues seen in previous studies. We carried out a cross-sectional study of adults in a population exposed to biomass smoke and a non-exposed population in Nepal. Questionnaire and lung function data were acquired along with direct measures of indoor and outdoor air quality. Ventilatory function (forced expiratory volume in 1 s (FEV(1)), forced vital capacity (FVC) and forced expiratory flow at 25-75% of FVC) was significantly reduced in the population using biomass across all age groups compared to the non-biomass-using population, even in the youngest (16-25 yrs) age group (mean FEV(1) (95% CI) 2.65 (2.57-2.73) versus 2.83 (2.74-2.91) L; p=0.004). Airflow obstruction was twice as common among biomass users compared with liquefied petroleum gas users (8.1% versus 3.6%; p|0.001), with similar patterns for males (7.4% versus 3.3%; p=0.022) and females (10.8%
Bioenergy, and in particular solid woody biomass, will play a crucial role in meeting the EUs 2020 renewable energy targets and mitigating climate change. This renewable energy source can provide reliable and base-load supply to meet EU energy needs. In order to realise the potential of biomass, AEBIOM1 and EURELECTRIC2 strongly advocate establishing harmonised, binding sustainability criteria for solid biomass on the EU level. EU utilities have already taken the lead in voluntary measures by collectively developing sustainability requirements for pelletised biomass and sourcing wood from certified forests (such as PEFC or FSC). The voluntary approaches should be substantiated and finalised by a legal framework at the EU level. Biomass imports continue to increase and sustainability criteria are needed.. Because bioenergy is a key technology in the EU renewables portfolio, delays in the introduction of EU criteria put the renewable energy target at risk, said Jean-Marc Jossart, Secretary ...
Pyrolysis is estimated to be one of the most promising methods to convert biomass to diverse products (such as syn-gas, liquid fuel and charcoal), while its application has the potential for alleviating the fossil fuel crisis and environmental deterioration. Cellulose, a linear homopolymer of glucopyranose residues linked by β-1, 4-glycosidic bonds, is the most principal component in biomass (accounting for more than 50% by weight). The research on the pyrolytic behavior of cellulose is particularly beneficial for achieving a better understanding of the pyrolytic behavior of biomass, also promoting its direct applications in terms of fuels, chemicals and bio-materials. The studies on pyrolysis of cellulose are extensively reported in the categories of the following four issues: (1) the physico-chemical properties of cellulose in lignocellulosic biomass; (2) the on-line pyrolysis study of cellulose; (3) the off-line pyrolysis study of cellulose; (4) the interactions with other chemical ...
A fully coupled meteorology‐chemistry‐aerosol mesoscale model (WRF‐Chem) is used to simulate a multiday biomass burning event in the dry season of South America. The effects of biomass burning aerosols on clouds and precipitation are described at both 36 km and 4 km horizontal resolutions. The dominant effect of the aerosols is to reduce the diurnal amplitude of convection by decreasing clouds and precipitation in the afternoon but increasing them at night, with the afternoon decrease greater than the nighttime increase on the daily mean. On average, the decrease of surface precipitation is about 5% (3%) and the amplitude of diurnal cycle is reduced by about 11% (5%) in the 36 km (4 km) simulations. Such a modulation of clouds and precipitation is primarily contributed by the aerosol radiative effect, i.e., their ability to scatter and absorb solar radiation. The aerosol microphysical effect as cloud condensation nuclei tends to act oppositely to the aerosol radiative effect but with a ...

In a move that could have wide ramifications for the future of biomass power nationwide, Massachusetts regulators have proposed to strictly regulate the ability of wood-burning incinerators to earn renewable power certificates.Its the latest twist in a long-running debate in the U.S. about whether biomass should qualify as a form of renewable energy and benefit from clean energy incentives. The draft rule by the Department of Energy Resources - unveiled late Friday - would require biomass incinerators to become 60 percent more efficient in order to earn full renewable energy credits and 40 percent to get a fraction of them. It would force a 50 percent cut in planet-warming gases from biomass plants by 2030 compared to fossil fuels, and limit the sorts of residues and waste wood that can be burned to discourage the poor forest management practice.Final regulations are expected be in place by the end of the year. Local environmentalists who have long fought a biomass boom said the announcement was a
