Use of molecular and isotopic techniques to monitor the response of autotrophic ammonia-oxidizing populations of the beta subdivision of the class proteobacteria in arable soils to nitrogen fertilizer. (1/369)

This study examined the effects of NH(4)NO(3) fertilizer on the size and activity of nitrifying, autotrophic, ammonia-oxidizing populations of the beta subdivision of the class Proteobacteria in arable soils. Plots under different long-term fertilizer regimes were sampled before and after NH(4)NO(3) additions, and the rates of nitrification were determined by (15)N isotopic pool dilution assays. Ammonia-oxidizing populations in the plots were quantified by competitive PCR assays based on the amoA and ribosomal 16S genes. Prior to fertilizer addition, ammonium concentrations and nitrification rates in the plots were comparatively low; ammonia-oxidizing populations were present at 10(4) to 10(5) gene copies g of soil(-1). Three days after the application of fertilizer, nitrification rates had risen considerably but the size of the ammonia-oxidizing population was unchanged. Six weeks after fertilizer treatment, ammonium concentrations and nitrification rates had fallen while the ammonia-oxidizing populations in plots receiving fertilizer had increased. The rapidity of the rise in nitrification rates observed after 3 days suggests that it results from phenotypic changes in the ammonia-oxidizing bacterial population. Associated increases in population sizes were only observed after 6 weeks and did not correlate directly with nitrifying activity. Phylogenetic analyses of PCR products from one of the plots revealed a population dominated by Nitrosospira-type organisms, similar to those prevalent in other soils.  (+info)

Purification, characterization, and gene analysis of a chitosanase (ChoA) from Matsuebacter chitosanotabidus 3001. (2/369)

The extracellular chitosanase (34,000 M(r)) produced by a novel gram-negative bacterium Matsuebacter chitosanotabidus 3001 was purified. The optimal pH of this chitosanase was 4.0, and the optimal temperature was between 30 and 40 degrees C. The purified chitosanase was most active on 90% deacetylated colloidal chitosan and glycol chitosan, both of which were hydrolyzed in an endosplitting manner, but this did not hydrolyze chitin, cellulose, or their derivatives. Among potential inhibitors, the purified chitosanase was only inhibited by Ag(+). Internal amino acid sequences of the purified chitosanase were obtained. A PCR fragment corresponding to one of these amino acid sequences was then used to screen a genomic library for the entire choA gene encoding chitosanase. Sequencing of the choA gene revealed an open reading frame encoding a 391-amino-acid protein. The N-terminal amino acid sequence had an excretion signal, but the sequence did not show any significant homology to other proteins, including known chitosanases. The 80-amino-acid excretion signal of ChoA fused to green fluorescent protein was functional in Escherichia coli. Taken together, these results suggest that we have identified a novel, previously unreported chitosanase.  (+info)

Janthinobacterium agaricidamnosum sp. nov., a soft rot pathogen of Agaricus bisporus. (3/369)

A novel bacterium has been found that causes a soft rot disease of Agaricus bisporus, the cultivated mushroom. It has been characterized using nutritional, physiological, chemical and molecular techniques. Based on these data, it was shown to have many characteristics in common with members of the genus Janthinobacterium. Despite similarities to the only described species within this genus, Janthinobacterium lividum, there were a number of differences between the mushroom pathogen isolated and this species. Despite the high degree of genotypic similarity between members of the genus Janthinobacterium and Herbaspirillum, as evidenced by DNA-RNA hybridization, and the high degree of 16S rDNA sequence similarity between members of the genera Janthinobacterium, Herbaspirillum, Oxalobacter and Duganella, as well as the generically misnamed Pseudomonas lemoignei, it was possible to show that members of the genus Janthinobacterium could be easily distinguished from these taxa. The data also indicated that the mushroom pathogenic strains represent a novel species within the genus Janthinobacterium for which the name Janthinobacterium agaricidamnosum sp. nov. is proposed. The type strain of this species has been deposited in the Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH, Braunschweig, Germany, as DSM 9628T and at the National Collection of Plant-pathogenic bacteria, UK, as NCPPB 3945T. To aid practical control of the disease, the effect of the relative humidity on symptom expression on Agaricus bisporus was determined.  (+info)

Endosymbiotic microbiota of the bamboo pseudococcid Antonina crawii (Insecta, Homoptera). (4/369)

We characterized the intracellular symbiotic microbiota of the bamboo pseudococcid Antonina crawii by performing a molecular phylogenetic analysis in combination with in situ hybridization. Almost the entire length of the bacterial 16S rRNA gene was amplified and cloned from A. crawii whole DNA. Restriction fragment length polymorphism analysis revealed that the clones obtained included three distinct types of sequences. Nucleotide sequences of the three types were determined and subjected to a molecular phylogenetic analysis. The first sequence was a member of the gamma subdivision of the division Proteobacteria (gamma-Proteobacteria) to which no sequences in the database were closely related, although the sequences of endosymbionts of other homopterans, such as psyllids and aphids, were distantly related. The second sequence was a beta-Proteobacteria sequence and formed a monophyletic group with the sequences of endosymbionts from other pseudococcids. The third sequence exhibited a high level of similarity to sequences of Spiroplasma spp. from ladybird beetles and a tick. Localization of the endosymbionts was determined by using tissue sections of A. crawii and in situ hybridization with specific oligonucleotide probes. The gamma- and beta-Proteobacteria symbionts were packed in the cytoplasm of the same mycetocytes (or bacteriocytes) and formed a large mycetome (or bacteriome) in the abdomen. The spiroplasma symbionts were also present intracellularly in various tissues at a low density. We observed that the anterior poles of developing eggs in the ovaries were infected by the gamma- and beta-Proteobacteria symbionts in a systematic way, which ensured vertical transmission. Five representative pseudococcids were examined by performing diagnostic PCR experiments with specific primers; the beta-Proteobacteria symbiont was detected in all five pseudococcids, the gamma-Proteobacteria symbiont was found in three, and the spiroplasma symbiont was detected only in A. crawii.  (+info)

Identification of polyphosphate-accumulating organisms and design of 16S rRNA-directed probes for their detection and quantitation. (5/369)

Laboratory-scale sequencing batch reactors (SBRs) as models for activated sludge processes were used to study enhanced biological phosphorus removal (EBPR) from wastewater. Enrichment for polyphosphate-accumulating organisms (PAOs) was achieved essentially by increasing the phosphorus concentration in the influent to the SBRs. Fluorescence in situ hybridization (FISH) using domain-, division-, and subdivision-level probes was used to assess the proportions of microorganisms in the sludges. The A sludge, a high-performance P-removing sludge containing 15.1% P in the biomass, was comprised of large clusters of polyphosphate-containing coccobacilli. By FISH, >80% of the A sludge bacteria were beta-2 Proteobacteria arranged in clusters of coccobacilli, strongly suggesting that this group contains a PAO responsible for EBPR. The second dominant group in the A sludge was the Actinobacteria. Clone libraries of PCR-amplified bacterial 16S rRNA genes from three high-performance P-removing sludges were prepared, and clones belonging to the beta-2 Proteobacteria were fully sequenced. A distinctive group of clones (sharing >/=98% sequence identity) related to Rhodocyclus spp. (94 to 97% identity) and Propionibacter pelophilus (95 to 96% identity) was identified as the most likely candidate PAOs. Three probes specific for the highly related candidate PAO group were designed from the sequence data. All three probes specifically bound to the morphologically distinctive clusters of PAOs in the A sludge, exactly coinciding with the beta-2 Proteobacteria probe. Sequential FISH and polyphosphate staining of EBPR sludges clearly demonstrated that PAO probe-binding cells contained polyphosphate. Subsequent PAO probe analyses of a number of sludges with various P removal capacities indicated a strong positive correlation between P removal from the wastewater as determined by sludge P content and number of PAO probe-binding cells. We conclude therefore that an important group of PAOs in EBPR sludges are bacteria closely related to Rhodocyclus and Propionibacter.  (+info)

Confirmation of Thiobacillus denitrificans as a species of the genus Thiobacillus, in the beta-subclass of the Proteobacteria, with strain NCIMB 9548 as the type strain. (6/369)

Thiobacillus denitrificans is physiologically similar to the type species of the genus Thiobacillus, Thiobacillus Thioparus, and both are located in the beta-subclass of the Proteobacteria. T. denitrificans is distinguished from all other Thiobacillus species by its ability to grow as a facultatively anaerobic chemolithotroph, coupling the oxidation of inorganic sulfur compounds to the reduction of nitrate, nitrite and other oxidized nitrogen compounds to dinitrogen. A definitive description of this species is provided and strain NCIMB 9548T is designated as the type strain of the species, thereby correcting an earlier error in the literature.  (+info)

Tepidimonas ignava gen. nov., sp. nov., a new chemolithoheterotrophic and slightly thermophilic member of the beta-Proteobacteria. (7/369)

A bacterial isolate with an optimum growth temperature of about 55 degrees C was recovered on a medium composed of one part Kligler's iron agar and four parts of Thermus Agar from the host spring at Sao Pedro do Sul in central Portugal. Phylogenetic analyses using the 16S rRNA gene sequence of strain SPS-1037T indicated that the new organism represented a new genus and species of beta-Proteobacteria. The major fatty acids of strain SPS-1037T are C16:0 and C17:0. Ubiquinone 8 is the major respiratory quinone, and the major polar lipids are phosphatidylethanolamine and phosphatidylglycerol. The new isolate is aerobic and chemolithoheterotrophic. Thiosulfate and tetrathionate were oxidized to sulfate. The growth yield of the organism was improved by the addition of thiosulfate to media containing organic carbon sources, but the organism did not grow autotrophically under the conditions examined. Heterotrophic growth of strain SPS-1037T occurs on amino acids and organic acids, but this organism does not assimilate carbohydrates. On the basis of the phylogenetic analyses, and physiological and biochemical characteristics, it is proposed that strain SPS-1037T represents a new genus and a new species for which the name Tepidimonas ignava is proposed.  (+info)

Description of Pandoraea gen. nov. with Pandoraea apista sp. nov., Pandoraea pulmonicola sp. nov., Pandoraea pnomenusa sp. nov., Pandoraea sputorum sp. nov. and Pandoraea norimbergensis comb. nov. (8/369)

A polyphasic taxonomic study was performed on a group of isolates tentatively identified as Burkholderia cepacia, Ralstonia pickettii or Ralstonia paucula (formerly known as CDC group IVc-2). The isolates were mainly cultured from sputum of cystic fibrosis patients or from soil. SDS-PAGE of whole-cell proteins and AFLP fingerprinting distinguished at least five different species, and this was confirmed by DNA-DNA hybridizations. 16S rDNA sequence analysis of representative strains indicated that these organisms belong to the beta-subclass of the Proteobacteria, with the genera Burkholderia and Ralstonia as closest neighbours. Based on genotypic and phenotypic characteristics, the organisms were classified in a novel genus, Pandoraea. The DNA base composition of the members of the new genus is between 61.2 and 64.3 mol%. This novel genus includes four new species, Pandoraea apista (the type species) (type strain is LMG 16407T), Pandoraea pulmonicola (type strain is LMG 18106T), Pandoraea pnomenusa (type strain is LMG 18087T) and Pandoraea sputorum (type strain is LMG 18819T), and Pandoraea norimbergensis (Wittke et al. 1997) comb. nov. (type strain is LMG 18379T). The available clinical data indicate that at least some of these organisms may cause chronic infection in, and can be transmitted amongst, cystic fibrosis patients.  (+info)

Several soluble c-type cytochromes were found in the periplasm. The optical difference spectrum of dithionite-reduced periplasmic extract shows that at least one of these components is capable of acting as an electron donor to the enzyme chlorate reductase. The cytochromes were partially separated, and the fractions were analyzed by UV/visible spectroscopy to determine the ability of donating electrons to chlorate reductase. Our results show that one of the c cytochromes (6 kDa) is able to donate electrons, both to chlorate reductase and to the membrane-bound cytochrome c oxidase, whereas the roles of the remaining c cytochromes still remain to be elucidated. Peptide extracts of the c cytochromes were obtained by tryptic in-gel digestion for matrix-assisted laser desorption ionization -time of ...

The victims were so emphatic, the threat of legal action so palpable, that John began calling every Delicata source in the country to find out exactly where his seed came from, and to make sure he didnt plant seed from the same lot again. Turns out, every dealer in the USA had seed from the same field in Colorado, and this huge lot was very slightly contaminated by the bitterness gene found in C. pepo gourds. Perhaps one bitter squash in several thousand...What to do? John had kept his own Delicata seed from 1988 thru 1994 (when he went over to buying commercial seed). We went into the freezer to find his old selection, and used this for stock seed in 2001. We found the fruits longer and more uniform, finer ...

Delicata is a small, oblong squash variety, with thin, edible skin. This recipe plays off its natural sweetness with savory elements like sage, garlic, Italian sausage, Parmesan and Romano cheese. Like a favorite fall sweater, this piece of my cooking ensemble is something Im always happy to dig out of the recipe files after a long, hot summer.. Swiss chard kicks up the nutrition without adding goitrogens, like those found in kale, collard greens, mustard greens, spinach, bok choy, and cabbage. However, if youre fond of those varieties, its helpful to note that cooking goitrogenic foods greatly reduces or eliminates their goitrogenic compounds. Speaking of which, there is one goitrogenic food included in this recipe, which is pine nuts. They are toasted to reduce goitrogens, but feel free to substitute another nut of your choice.

In the aerobic phase of the biological phosphorus removal process, poly-β-hydroxybutyrate, produced during anaerobic conditions, is used for cell growth, phosphate uptake, and glycogen formation. A metabolic model of this process has been developed. The yields for growth, polyphosphate and glycogen formation are quantified using the coupling of all these conversions to the oxygen consumption. The uptake of phosphate and storage as polyphosphate is shown to have a direct effect on the observed oxygen consumption in the aerobic phase. The overall energy requirements for the P-metabolism are substantial: 25% of the acetate consumed during anaerobic conditions and 60% of the oxygen consumptions is used for the synthesis of polyphosphate and glycogen. © 1994 John Wiley & Sons, Inc. ...

Herbaspirillum seropedicae SmR1 is a nitrogen fixing endophyte associated with important agricultural crops. It produces polyhydroxybutyrate (PHB) which is stored intracellularly as granules. However, PHB metabolism and regulatory control is not yet well studied in this organism. In this work we describe the characterization of the PhbF protein from H. seropedicae SmR1 which was purified and characterized after expression in E. coli. The purified PhbF protein was able to bind to eleven putative promoters of genes involved in PHB metabolism in H. seropedicae SmR1. In silico analyses indicated a probable DNA-binding sequence which was shown to be protected in DNA footprinting assays using purified PhbF. Analyses using lacZ fusions showed that PhbF can act as a repressor protein controlling the expression of PHB metabolism-related genes. Our results indicate that H. seropedicae SmR1 PhbF regulates expression of phb-related genes by acting as a transcriptional repressor. The knowledge of the PHB metabolism

This pathway was contributed by Charlotte Rosendahl Pedersen and updated by Carla Essenberg and Michael Turnbull, University of Minnesota. Methyl tert-butyl ether (MTBE), an additive to gasoline, is used to replace other toxic components such as lead. This additive reduces the emissions of airborn toxics, carbon monoxide and volatile organic compounds. This compound was first used in the US in the 70s, but since the 1990 Clean Air Act, its use has gone up immensely. It is now the second most produced chemical in the US with more than 24 billion pounds used per year. There are problems with the storage of MTBE; it is now the second most common contaminant of urban aquifers in the US. MTBE is becoming a problem in drinking water too, and the toxicity of MTBE is not very well known. Some studies show that, in humans exposed to high amounts of MTBE in drinking water, it might induce programmed cell death. While a number of microorganisms are known to metabolize MTBE, not much is known about the ...
TY - JOUR. T1 - Impact of water boundary layer diffusion on the nitrification rate of submerged biofilter elements from a recirculating aquaculture system. AU - Prehn,Jonas.

N2 - Total ammonia nitrogen (TAN) removal by microbial nitrification is an essential process in recirculating aquaculture systems (RAS). In order to protect the aquatic environment and fish health, it is important to be able to predict the nitrification rates in RASs. The aim of this study was to determine the impact of hydraulic film diffusion on the nitrification rate in a submerged biofilter. Using an experimental batch reactor setup with recirculation, active nitrifying biofilter units from a RAS were exposed to a range of hydraulic flow velocities. Corresponding nitrification rates were measured following ammonium chloride, NH4Cl, spikes and the impact of hydraulic film diffusion was quantified. The nitrification ...

The Messalonskee Stream in central Maine has five hydroelectric dams on 16.6km. Each dam drastically changes the flow regime of the stream, dividing it into segments with different patterns of sediment settling and organic matter retention. I investigated how these disruptions impact nitrogen cycling, specifically nitrification rates above and below each dam. I expected higher nitrification rates above the dams, where levels of organic matter are higher, and lower rates below the dam where scouring removes organic matter and fine sediment from the streambed. I measured sediment nitrification rates with a nitrapyrin-inhibition assay and potential drivers of nitrification including sediment organic matter and pore water ammonia (NH4 +) above and below each dam. Nitrification rates ranged from 0-1490 μg NH4 + g AFDM -1 day-1 with an average of 105μg NH4 + g AFDM -1 day-1 showing a wide range of variation with no consistent pattern between above and below sites. Variation among the five dam sites is due

By numbers alone, viruses rule the oceans. They also outnumber every other microorganism in lakes, rivers and rivulets.. "In every environment, you find somewhere around 10 million virus particles per milliliter (of water)," Fischer said. "It doesnt matter whether you go out in the open ocean, whether you go to the bottom of the ocean, whether you go to freshwater ponds, soil samples - they pretty much always have viruses as the most abundant biological entities.". "The big ecological question is, What is the effect of these viruses, right? Now, do they all kill the hosts and are bad for them?" Fischer said. "No, that doesnt seem to be the case. Instead, it looks like theyre fueling the ecosystem by providing nutrients.". Giant marine viruses such as Wilhelms quarry AaV accomplish this by breaking up blooms of phytoplankton, whose bodies then rain down to the seafloor to sequester carbon. By doing so, AaVs return valuable phosphorus, iron and nitrogen that had been hoarded by a handful of ...

We present an advanced system for on-line position-specific carbon isotope analysis. The main limitation of on-line intramolecular isotope ratio measurements has been that optimal pyrolytic fragments are obtained mostly at temperatures where the analyte has not completely reacted. As a result of undetermined isotopic fractionation, the isotopic signatures of the pyrolysis products are not strictly equal to these of the equivalent moieties in the parent molecule. We designed a pyrolytic unit in which both temperature and reaction time are variable parameters, enabling determination of the enrichment factor of the pyrolysis at optimal temperature by construction of a Rayleigh plot. In the case of methyl tert-butyl ether (MTBE) presented here, a pre-pyrolysis fractionation of MTBE leading to a depletion of 0.9 parts per thousand was discovered and the enrichment factor of the optimal pyrolysis reaction was determined at -1.7 parts per thousand. Absolute delta C-13 values of two functional groups ...
Enhanced biological phosphorus removal (EBPR) is a sewage treatment configuration applied to activated sludge systems for the removal of phosphate. The common element in EBPR implementations is the presence of an anaerobic tank (nitrate and oxygen are absent) prior to the aeration tank. Under these conditions a group of heterotrophic bacteria, called polyphosphate-accumulating organisms (PAO) are selectively enriched in the bacterial community within the activated sludge. These bacteria accumulate large quantities of polyphosphate within their cells and the removal of phosphorus is said to be enhanced. Generally speaking, all bacteria contain a fraction (1-2%) of phosphorus in their biomass due to its presence in cellular components, such as membrane phospholipids and DNA. Therefore, as bacteria in a wastewater treatment plant consume nutrients in the wastewater, they grow and phosphorus is incorporated into the bacterial biomass. When PAOs grow they not only consume phosphorus for cellular ...
Discharge of wastewater containing excess amounts of nutrients such as phosphorus (P) cause eutrophication of the receiving waterbodies. The consequences related to eutrophication can vary in severity, from esthetical issues to medical threats. The increasing focus on P as a non-renewable resource and the necessity for recovering and recycling P from nutritious wastewater has made biological phosphorus removal (EBPR) in wastewater a more favorable method compared to chemical precipitation. EBPR is a complex process where several essential process conditions and prerequisites make Norwegian wastewater, which typically is diluted and low in nutrients, less ideal for EBPR.. In this study, the possibility of applying EBPR in a local and presumably typical Norwegian wastewater (Lerkendal wastewater) was examined. The objectives of this work were to characterize the unknown wastewater in terms of relevant substances according to EBPR, and perform batch experiments to assess the bio-P activity in the ...

article{1b9c5591-fb32-44ff-a023-1f4fc5770fd9, abstract = {The paper deals with the effect of wastewater, plant design and operation in relation to biological nitrogen and phosphorus removal and the possibilities to model the processes. Two Bio-P pilot plants were operated for 2.5 years in parallel receiving identical wastewater. The plants had SRT of 4 and 21 days, the latter had nitrification and denitrification. The plant with 4 days SRT had much more variable biomass characteristics, than the one with the high SRT. The internal storage compounds, PHA, were affected significantly by the concentration of fatty acids or other easily degradable organics in the wastewater, and less by the plant lay-out. The phosphorus removal is mainly dependent on availability in the wastewater of fatty acids but also by the suspended solids in the effluent, which is higher in the plant with nitrification-denitrification, probably due to a higher SVI or denitrification in the settler. The addition of glucose to ...
This study investigated the characteristics of denitrifying phosphorus removal bacteria by using three different types of electron acceptors as well as the positive role of nitrite in phosphorus removal process. Denitrifying phosphorous removal bacteria was enriched under anaerobic-anoxic (A/A) condition. To understand A/A sludge better, sludge from two other sources were also studied. These include sludges obtained from a lab-scale anaerobic-anoxic-aerobic (A/A/O) system and a local sewage treatment plant. Three types of possible electron acceptors (oxygen, nitrate and nitrite) were examined for their roles in phosphorus uptake. The results obtained indicated that oxygen, nitrate and nitrite were able to act as electron acceptors successfully. This observation suggested that in addition to the two well-accepted groups of phosphorus removal bacteria (one can only utilize oxygen to take up phosphorus, PO, while the other can use both oxygen and nitrate, PON), a new group of phosphorus removal ...
Mealybugs (Hemiptera: Pseudococcidae) cause severe damage to many commercial crops, including grapevine. This is largely because of their ability to transmit various grapevine viral diseases, in particular grapevine leafroll-associated viruses (GLRaVs). Grapevine leafroll is one of the most wide-spread grapevine diseases worldwide. Managing the field-spread of grapevine leafroll disease requires, amongst others, stringent mealybug control. Mealybug monitoring and control methods rely on timely and accurate identification of the species present. However, proper identification of mealybug species is problematic, time-consuming and requires an expert taxonomist. In most cases, only adult females can be reliably identified morphologically. Immature insects, males and damaged specimens cannot be assigned to species. In this study, a molecular method was developed to rapidly and accurately distinguish three mealybug species associated with grapevine, namely the vine mealybug Planococcus ficus ...

Ammonia-oxidizing bacteria (AOB) are key organisms in the N cycle, as they control the first, rate-limiting step of the nitrification process. The question whether current environmental disturbances, such as climate warming and plant diversity losses, select for a particular community structure of AOB and/or influence their activity remains open. The purpose of this research was to study the impact of a 3 °C warming and of plant species richness (S) on microbial activity and diversity in synthesized grasslands, with emphasis on the nitrification process and on the diversity (community structure and richness) of ammonia-oxidizing bacteria (AOB).We measured soil chemical characteristics, basal respiration, potential nitrification and AOB ...

A pilot-scale, pre-anoxic-anaerobic oxidation ditch was used in this study to treat municipal wastewater with limited carbon source. A novel return activated sludge (RAS) pre-concentration tank was adopted for improving the phosphorus removal efficiency and the effects of RAS pre-concentration ratio were studied. Under the optimal operational condition, the suspended total phosphorus (STP) and the total phosphorus (TP) removal efficiencies were around 58.9% and 63.9% respectively and the effluent PO3-4 -P was lower than 0.8 mg•L−1. The reason is that with the optimal RAS pre-concentration ratio, nitrate is completely removed with endogenous carbon source and the secondary phosphorus release is strictly restrained in the pre-anoxic tank. Therefore, the anaerobic phosphorus release and the carbon source uptake by phosphorus accumulation organisms (PAOs) in the sludge, which are extremely important to the phosphorus removal process, can be fully satisfied. Furthermore, the oxidation-reduction ...

A Gram-negative, strictly aerobic bacterium, designated strain byr23-80T, was isolated from lysimeter soil by using a high-throughput cultivation technique. Cells of strain byr23-80T were found to be short rods that multiplied by binary fission and were motile by means of a single polar flagellum. Occasionally, two to three polar or lateral flagella were observed. The optimum growth temperature was 15 °C and the pH optimum was 7.0-7.5. The predominant cellular fatty acids were C16 : 1 ω7c (54.7 %) and C16 : 0 (21.4 %). In addition, the diagnostic fatty acids C10 : 0 3-OH and C12 : 0 2-OH were detected. Q-8 was the predominant respiratory quinone. The isolate was physiologically very versatile, using a wide range of sugars, organic acids and amino acids as single carbon and energy sources for growth. The G+C content of the genomic DNA was 65.3 mol%. Phylogenetic analyses supported the assignment of strain byr23-80T to the genus Massilia within the family Oxalobacteraceae of the class Betaproteobacteria

In this work, we examined the profile of metabolites produced from the doubly para-substituted biphenyl analogs 4,4-dihydroxybiphenyl, 4-hydroxy-4-chlorobiphenyl, 3-hydroxy-4,4-dichlorobiphenyl, and 3,3-dihydroxy-4,4-chlorobiphenyl by biphenyl-induced Pandoraea pnomenusa B356 and by its biphenyl dioxygenase (BPDO). 4-Hydroxy-4-chlorobiphenyl was hydroxylated principally through a 2,3-dioxygenation of the hydroxylated ring to generate 2,3-dihydro-2,3,4-trihydroxy-4-chlorobiphenyl and 3,4-dihydroxy-4-chlorobiphenyl after the removal of water. The former was further oxidized by the biphenyl dioxygenase to produce ultimately 3,4,5-trihydroxy-4-chlorobiphenyl, a dead-end metabolite. 3-Hydroxy-4,4-dichlorobiphenyl was oxygenated on both rings. Hydroxylation of the nonhydroxylated ring generated 2,3,3-trihydroxy-4-chlorobiphenyl with concomitant dechlorination, and 2,3,3-trihydroxy-4-chlorobiphenyl was ultimately metabolized to 2-hydroxy-4-chlorobenzoate, but hydroxylation of the ...

Nevertheless, breaking down the durable thylakoid membrane of Synechocystis to get at the valuable lipids is not an easy task. As Sheng explains, alternate, less toxic chemicals have been used with success to extract lipid from algae, including ethanol, isopropanol, butanol, methyl tert-butyl ether (MTBE), acetic acid esters, hexane, and various combinations of these, but their viability for use with cyanobacteria was uncertain.

Locally Adapted Seeds. This is mostly about vegetables but the ideas apply to just about any seed bearing plant.. Why Bother. Are your favorite varieties of Kale, Cauliflower, Onions, Peas, or Zucchini hard to find this year ? Are all those seeds, are all your seeds coming from someplace else ? Do you ever wonder why that is ?. Farmers have been selecting and saving seeds since the dawn of Agriculture. Why arent we doing that anymore ? There used to be 100s of regional seed companies, with dozens in Minnesota and Wisconsin. Now, three corporations control more than half of the worldwide seed business and none of them are located here.. I had been resistant to saving vegetable seeds for years. I didnt want to wait until harvest time to find out that I had a seed crop failure. If two thirds of your purchased Delicata seed doesnt emerge you know you have a problem, but you might have time to do something. If your Delicata crop matures to be some weird zucchini - spaghetti squash hybrid, you have ...
Aerobic and anaerobic cultivation techniques, 16S rDNA-based phylogeny, and fluorescent in situ hybridization were used to describe the phylogenetic diversity and physiological versatility of lotic microbial aggregates (river snow) obtained from the river Elbe. In the course of the year the river snow community changed. It was characterized by a great bacterial diversity in spring, the predominant occurrence of algae in summer and reduction of the total bacterial cell count in autumn and winter. In all river snow samples, more than 70% of the bacteria counted with the general DNA stain DAPI also hybridized with the Bacteria-specific probe EUB338. In situ analysis of the bacterial river snow community with a comprehensive suite of specific rRNA-targeted probes revealed population dynamics to be governed by seasonal factors. During all seasons, beta-Proteobacteria constituted the numerically most important bacterial group forming up to 54% of the total cell counts. In contrast to this, the ...

I recently heard that pound for pound, ants outweigh mammals. Yes, all mammals. Its amazing they outweigh a single blue whale, much less all of us warm-blooded, hairy animals. Now, I dont know how anyone would go about actually calculating such a figure but my point is, thats a lot of ants. It makes me not feel so bad about accidentally squashing one once in a while. I dont go out of my way to torture them like I did when I was a kid, drowning them or feeding them to ant lions and such (yes, I know--Im awful) but maybe it is time to reconsider a personal crusade against the pesky insects. It seems like theyve been nothing but trouble here and trouble is being generous ...

Drinking water chloramine use may promote ammonia-oxidizing bacteria (AOB) growth because of naturally occurring ammonia, residual ammonia remaining from chloramine formation, and ammonia released from chloramine decay and demand. A rapid chloramine residual loss is often associated with the onset of nitrification that may result in noncompliance with existing regulations; therefore, understanding nitrification and its control in drinking water is of practical importance. For biological ammonia oxidation (1st nitrification step), AOB use two enzymes in two consecutive reactions: (1) ammonia monooxygenase (AMO) catalyzes ammonia oxidation to hydroxylamine and (2) hydroxylamine oxidoreductase catalyzes hydroxylamine oxidation to nitrite, supplying electrons back to AMO for ammonia oxidation. Chloramine also inactivates AOB but rates vary, depending on inactivation criterion (metabolic activity, culturability, cell membrane integrity). One mechanism for the fastest inactivation (metabolic activity ...
Nitrifying biofilters degrading the four regulated trihalomethanes (THMs) trichloromethane (TCM), bromodichloromethane (BDCM), dibromochloromethane (DBCM), and tribromomethane (TBM) -were analyzed for the presence and activity of ammonia-oxidizing bacteria (AOB). Biofilter performance and batch kinetic tests performed on biofilm removed during backwashing verified that the biofilters contained organisms capable of degrading the four regulated THMs commonly found in treated drinking water. Quantitative PCR (qPCR) and amoA sequence analysis provided evidence that the Nitrosomonas oligotropha was the only AOB present. N. oligotropha is typically associated with drinking water distribution system AOB communities, and their presence in these biofilters might indicate that their tolerance to THMs is another reason for their dominance in chloraminated drinking water systems. ...
Although ammonia-oxidizing archaea (AOA) and bacteria (AOB) coexist in most non-acidic agricultural soils, the factors that influence their relative contributions to soil nitrification activity remain unclear. A 2- to 4-d whole soil microcosm assay was developed, utilizing the aliphatic C₈ alkyne 1-octyne to inactivate AOB-driven nitrification activity without impacting AOA nitrification activity. Responses of AOA- and AOB-supported net nitrification activities (accumulation of NO₂⁻ + NO₃⁻) to different concentrations of extractable NH₄⁺ were examined in four diverse, paired cropped and non-cropped Oregon soils sampled in summer and winter. Maximum AOA-supported net nitrification rates were significantly higher in non-cropped (3.7 mg N kg⁻¹ soil d⁻¹) than in cropped soils (0.9 mg N kg⁻¹ soil d⁻¹) and in summer (3.1 mg N kg⁻¹ soil d⁻¹) compared with winter soils (1.6 mg N kg⁻¹ soil d⁻¹). The NH₄⁺ concentration required to significantly stimulate AOB ...

Nitrosomonas - WikipediaNitrosomonas - Wikipedia

Nitrosomonas is a genus of Gram-negative rod-shaped chemoautotrophic bacteria.[2] This organism oxidizes ammonia into nitrite as a metabolic process. Nitrosomonas are useful in bioremediation. They are important in the nitrogen cycle by increasing the availability of nitrogen to plants while limiting carbon dioxide fixation.[2] The genus is found in soil, freshwater, and on building surfaces, especially in areas that contains high levels of nitrogen compounds. Nitrosomonas prefers an optimum pH of 6.0-9.0 and a temperature range of 20 to 30 °C. Most species are motile with a flagellum located in the polar regions. The organism has power generating membranes, which form long, thin tubes inside the cell. These use electrons from the oxidation of ammonia to produce energy.[2] It obtains the carbon it requires from the atmosphere via carbon fixation, which converts carbon in a gaseous form into carbon bound in organic molecules. Unlike plants, which fix carbon into sugar through energy gained ...
