Bacteriophage-encoded lytic enzymes control growth of contaminating Lactobacillus found in fuel ethanol fermentations |...The goal of this study was to identify phage exolytic lysins that can be used as antimicrobials toward Gram positive LAB known to contaminate fuel ethanol fermentations. From seven putative lysin genes, we have identified four phage lysins (LysA, Lysa2, LysgaY and λSa2 endolysin), that show high activity against LAB contaminants from fuel ethanol facilities. These enzymes have broad exolytic activity in vitro towards numerous Gram positive LAB including several fermentation isolates of L. fermentum. Although LysA, LysA2 and LysgaY, and λSa2 endolysin all demonstrated exolytic activity against lactobacilli, the lactobacilli lysin LysA and the streptococcal λSa2 phage endolysin showed the greatest efficacies to reduce populations of L. fermentum. Interestingly, λSa2 endolysin also exhibited the broadest lytic activity towards the LAB and other Gram positive bacteria tested here.. It is virtually impossible to avoid LAB contaminations in fuel ethanol fermentations, and therefore, the risk of ...

Biofuels... are fuels produced from biomass, i.e. organic matter that comes from a biological process, which is usable as an energy source.. According to the raw material and technology used in its production, biofuels can be classified into first, second and third generation. First generation biofuels use food grade raw materials and process technologies such as fermentation and transesterification; it is mainly these that have reached a commercial production stage. Second generation biofuels are derived from raw materials that have no food use, through the aforementioned processes and through thermochemical processes. Finally, third-generation biofuels use similar production methods in specifically designed or adapted bioenergy crops; these are still at an early stage of development and are a long way from being produced on a commercial scale.. Some noteworthy aspects of biofuels are:. ...
EU Parliament vote on biofuels - Nuffield BioethicsThe Nuffield Council on Bioethics welcomes the outcome of today's vote, which comes more than two years after the Council published its report Biofuels: ethical issues. The report recommended that biofuels policies should take into account the possible greenhouse gas emission savings over the whole production lifecycle of the biofuels, but noted the complexities associated with calculating and determining ILUC factors. It also recommended that policy makers should incentivise research and development of new biofuels technologies that need less land and other resources.. The European Commission previously established voluntary sustainability criteria for biofuels. However the Council would like to see mandatory certification of biofuels that includes social as well as environmental sustainability criteria and greenhouse gas emissions savings. The social criteria that the Council would like to see incorporated ...
Getting from here to there: Biofuels may prove more volatile than oil for transportation fuelThis story is the NY Times raises alarms that biofuels are subject to weather risks. As climate change is likely to increase weather swings and cause great damage to crops in the future, it seems that wholly embracing biofuels is not sound policy. Since the country is freaked out by the rising price of oil and there is no reasonable expectation of a major decline anytime soon (I'm doubtful of any type of speculative bubble in the oil market), switching to a fuel source that is more unpredicatable-at the cost of higehr food prices no less- may force uncomfortable and unpleasant choices in the future between mobility and hunger. It seems that biofuels will not solve many of the problems associated with transportation energy and will likely cause more severe and unexpected problems in the coming decades. Perhaps hydrogen is the way to go ...

Sunlight converts algae fats directly into hydrocarbons for speedy biofuel production : Biofuels DigestIn France, researchers discovered that certain species of algae can convert fats directly to hydrocarbons that can come in handy for biofuel production. Using sunlight as an input and filtering the contents of algae to leave them with protein solutions with some cell contents, they tested them for how well they converted to fats. They found a set of 10 proteins that existed in all three fractions that were able to convert fats, but one of them was a mystery protein. Once they identified that mystery protein's gene, they tweaked it and transferred it to bacteria where it converted fats to hydrocarbons. Interestingly, the reaction needed blue light to work and when they switched it to red light, the conversion process stopped. The discovery can lead to many applications that rely on algae fat conversion to hydrocarbons, like biofuel production. ...

Comparative transcriptome analysis to investigate the high starch accumulation of duckweed (Landoltia punctata) under nutrient...Liquid biofuels, such as bioethanol, converted from biomass are considered as a promising alternative for traditional fossil fuels. Biofuels development can reduce greenhouse gas emission and meet the world's rapidly growing demand for energy. Currently, bioethanol is mainly produced from feedstocks with relatively high starch or sugar percentage, such as corn, sugarcane, sweet potato and cassava [1-3]. However, these bioethanol production modes have some inherent problems, including the adverse impacts on food security, environment and insufficient agricultural land [4, 5]. Although lignocellulosic sources are also considered as a promising feedstock for bioethanol production, there are several obstacles, such as the lack of an efficient, economical and environment friendly pretreatment process, that still needed to be overcome . Therefore, developing sustainable feedstocks and processing protocols for biofuel production is becoming more and more urgent.. One alternative ...
Scaling Biofuels Technology : Biofuels DigestRecommendations. First and foremost, for companies actively engaged in developing biofuels or bioenergy technology, it is recommended that they systematically follow the stage gate approach outlined in this article as they scale their process technology in order to minimize risk and maximize the likelihood of success. In planning the timeframe to develop the technology through the pilot and demonstration stages it is important to consider that the time required for start-up and commissioning of the plants will take longer than a traditional gas-liquid plant due mainly to the extra time required to fine tune the solids handling equipment.. Secondly, it is important that technology companies choose to work with partners and suppliers with real experience and a proven track record in the bioenergy and biofuels segment. Ideally, this experience should be drawn from the successful execution of bioenergy projects of similar scale and complexity, or else from projects in related ...
Court of Appeals punctures a hole in EPA's cellulosic ethanol balloonThrough the Clean Air Act, the EPA can mandate a set volume of cellulosic biofuels that refiners must blend into gasoline based on "the projected volume available." In 2007, the Energy Independence and Security Act (EISA) established annual renewable fuel volume targets. The "targets" increase each year to reach 36 billion gallons by 2022. The EISA's original cellulosic biofuel expectation for 2013 was 1 billion gallons.. The targets gave birth to a new cellulosic ethanol industry. Thanks to the government mandates, start-ups such as Range Fuels and Cello Energy were born. They cranked out press releases touting a potential for millions of gallons of the biofuel. Based on optimistic projections aimed at attracting investors, the EPA set its targets.. In 2006, President Bush pledged government funding for the nascent industry-declaring that cellulosic ethanol would be "practical and competitive within six years." Range Fuels received a $76 million grant from the Department of Energy in March ...

Acid-catalyzed algal biomass pretreatment for integrated lipid and carbohydrate-based biofuels production - Green Chemistry ...TEA results for the base case algal cultivation productivity of 13.2 g m−2 day−1 show promising economic potential for this technology pathway, with an 18% improvement (reduction) in MFSP based on currently observed experimental results relative to the lipid-focused benchmark $($16.31/GGE versus $$19.80/GGE respectively), or a 33% improvement for the theoretical "improved" conversion case $($13.35/GGE) (Fig. 3, scenario A-C). This improvement is driven in large part by the substantial increase in total fuel yield, at 27% increase for the "baseline experimental" case relative to the benchmark (1299 versus 1023 GGE per acre-year respectively), or 54% increase for the "improved" case (1577 GGE per acre-year). Extrapolating further to concomitantly increased algal cultivation productivity combined with the "improved" conversion case, the present technology pathway shows the potential to maintain an approximate 33% improvement in MFSP relative to the harmonization baseline technology at either 30 ...

Iowa: Biofuels Represent 3.5% of the State's Gross Domestic Product - DTN | AgFaxPruitt's confirmation vote is expected to come sometime likely Thursday or Friday.. Ethanol interest groups continue expressing confidence President Donald Trump will stand behind the RFS. Trump declared his support for biofuels during the presidential campaign and Pruitt has told various Midwestern lawmakers he would continue to implement the law as written.. "As written" is the key phrase. There has been a fair amount of rumbling in Congress about a need for RFS reform. The proposals range from limiting ethanol content in gasoline to 9.7%, to outright repeal.. Considering Trump's penchant for keeping jobs in America and the electoral support he saw from rural America, perhaps the biofuels industry's best tact is to continue to stress the economic importance of the policy.. Long-time ethanol industry consultant John Urbanchuk, managing partner, Agriculture and BioFuels Consulting, LLP, outlined in a recent study how the industry has driven the economy of ...

It was named after its inventor, Benjamin Thompson, also known as Count Rumford, and is sometimes called a Rüdersdorf furnace after the location where it was first built and from where the design rapidly spread throughout Europe.Revegetation: Revegetation is the process of replanting and rebuilding the soil of disturbed land. This may be a natural process produced by plant colonization and succession, or an artificial (manmade) wilderness engineering, accelerated process designed to repair damage to a landscape due to wildfire, mining, flood, or other cause.Chilalo Agricultural Development Union: Chilalo Agricultural Development Union (CADU) is the first comprehensive package project established in Arsi Zone, Oromia Region, Ethiopia to modernize traditional subsistence agriculture. The major components of the package programmes include fertilizers, ameliorated seeds, farm credits, marketing facilities, better tools and implements, and improved storage facilities.Ethanol fuel: Ethanol fuel is ethanol (ethyl alcohol), the same type of alcohol found in alcoholic beverages. It is most often used as a motor fuel, mainly as a biofuel additive for gasoline.Lactic acid fermentationCarbon–carbon bond: A carbon–carbon bond is a covalent bond between two carbon atoms. The most common form is the single bond: a bond composed of two electrons, one from each of the two atoms.National Offshore Petroleum Safety Authority: The National Offshore Petroleum Safety Authority (NOPSA) was the occupational health and safety (OHS) regulator for the Australian offshore petroleum industry between 2005 and 2011. The role of regulator has been transferred to NOPSEMA - the National Offshore Petroleum Safety and Environmental Management Authority from the first of January 2012.D-xylose reductase: D-xylose reductase (, XylR, XyrA, msXR, dsXR, monospecific xylose reductase, dual specific xylose reductase, NAD(P)H-dependent xylose reductase, xylose reductase) is an enzyme with system name xylitol:NAD(P)+ oxidoreductase. This enzyme catalyses the following chemical reactionPrimary alcoholPeat swamp forest: Peat swamp forests are tropical moist forests where waterlogged soil prevents dead leaves and wood from fully decomposing. Over time, this creates a thick layer of acidic peat.Meramec Conservation AreaSynechocystis: Synechocystis is a genus of unicellular, freshwater cyanobacteria primarily represented by the strain Synechocystis sp. PCC6803.Glucuronoxylan: Glucuronoxylans are the primary components of hemicellulose as found in hardwood trees, for example birch.http://www.Index of soil-related articles: This is an index of articles relating to soil.Trichoderma harzianum: Trichoderma harzianum is a fungus that is also used as a fungicide. It is used for foliar application, seed treatment and soil treatment for suppression of various disease causing fungal pathogens.Marine fungi: Marine fungi are species of fungi that live in marine or estuarine environments. They are not a taxonomic group but share a common habitat.

(8/418) Properties of ethanol fermentation by Flammulina velutipes.
Basidiomycetes have the ability to degrade lignocellulosic biomass, and some basidiomycetes produce alcohol dehydrogenase. These characteristics may be useful in the direct production of ethanol from lignocellulose. Ethanol fermentation by basidiomycetes was investigated to examine the possibility of ethanol production by consolidated bioprocessing (CBP) using Flammulina velutipes. F. velutipes converted D-glucose to ethanol with a high efficiency (a theoretical ethanol recovery rate of 88%), but ethanol production from pentose was not observed. These properties of F. velutipes are similar to those of Saccharomyces cerevisiae, but the basidiomycete converted not only sucrose, but also maltose, cellobiose, cellotriose, and cellotetraose to ethanol, with almost the same efficiency as that for D-glucose. From these results, we concluded that F. velutipes possesses advantageous characteristics for use in CBP. (+info)
