Napiergrass: A Possible Biofuel Crop For The Sunny Southeast
2012-09-28 12:52:47

A grass fed to cattle throughout much of the tropics may become a biofuel crop that helps the nation meet its future energy needs, according to a U.S. Department of Agriculture (USDA) scientist. Napiergrass (Pennisetum purpureum) is fairly drought-tolerant, grows well on marginal lands, and filters nutrients out of runoff in riparian areas, according to William Anderson, a geneticist in the Agricultural Research Service (ARS) Crop Genetics and Breeding Research Unit in Tifton, Ga. ARS is...

Sorghum Candidate For Southern Bioenergy Crop
2012-09-17 12:43:34

Sweet sorghum is primarily grown in the United States as a source of sugar for syrup and molasses. But the sturdy grass has other attributes that could make it uniquely suited to production as a bioenergy crop, U.S. Department of Agriculture (USDA) studies suggest. Sorghum is an ideal candidate because of its drought tolerance, adaptability to diverse growing conditions, low nitrogen fertilizer requirements, and high biomass (plant material) content, according to molecular biologist Scott...

A Microbe Which Can Handle Ionic Liquids
2012-05-15 05:23:38

New find from Joint BioEnergy Institute could help reduce biofuel production costs In the search for technology by which economically competitive biofuels can be produced from cellulosic biomass, the combination of sugar-fermenting microbes and ionic liquid solvents looks to be a winner save for one major problem: the ionic liquids used to make cellulosic biomass more digestible for microbes can also be toxic to them. A solution to this conundrum, however, may be in the offing....

Studies of bacteria first found in Yellowstone's hot springs are furthering efforts at the Department of Energy's BioEnergy Science Center toward commercially viable ethanol production from crops such as switchgrass. The current production of ethanol relies on the use of expensive enzymes that break down complex plant materials to yield sugars that are fermented into ethanol. One suggested cheaper alternative is consolidated bioprocessing, a streamlined process that uses microorganisms to...

Computer Model Optimizes Biofuel Operations
2012-01-18 05:00:56

Research into biofuel crops such as switchgrass and Miscanthus has focused mainly on how to grow these crops and convert them into fuels. But many steps lead from the farm to the biorefinery, and each could help or hinder the growth of this new industry. A new computer model developed at the University of Illinois can simplify this transition, researchers say. The model can run millions of simulations, optimizing operations to bring down costs, reduce greenhouse gas emissions or achieve...

Innovations in RNA manipulation could lead to advances in many products Researchers at the U.S. Department of Energy's (DOE's) Joint BioEnergy Institute (JBEI) announced today a major breakthrough in engineering systems of RNA molecules through computer-assisted design, which could lead to important improvements across a range of industries, including the development of cheaper advanced biofuels. Scientists will use these new "RNA machines", to adjust genetic expression in the cells of...

Maximizing greenhouse gas savings Scientists examined current knowledge about the potential contributions of bioenergy production from switchgrass to limit greenhouse gas emissions. Their findings, published in GCB Bioenergy, conclude that the use of switchgrass bioenergy can contribute to reducing greenhouse gas emissions but encourage further research to address the significant sources of uncertainty, such as what type of land is converted to switchgrass. According to the leading...

Joint BioEnergy Institute (JBEI) Researchers Reach Milestone on the Road to Biofuels A milestone has been reached on the road to developing advanced biofuels that can replace gasoline, diesel and jet fuels with a domestically-produced clean, green, renewable alternative. Researchers with the U.S. Department of Energy (DOE)´s Joint BioEnergy Institute (JBEI) have engineered the first strains of  Escherichia coli bacteria that can digest switchgrass biomass and synthesize its...

Scientists at the U.S. Department of Agriculture (USDA) are leading the way in learning more about "biochar," the charred biomass created from wood, other plant material, and manure. The studies by Agricultural Research Service (ARS) scientists at laboratories across the country support the USDA priorities of promoting international food security and responding to global climate change. ARS is USDA's chief intramural scientific research agency. Soil scientist Jeff Novak at the ARS...

Adding a pretreatment step would allow producers to get more ethanol from switchgrass harvested in the fall, according to a Purdue University study. Michael Ladisch, a distinguished professor of agricultural and biological engineering, and Youngmi Kim, a research scientist, compared switchgrass based on growing location, harvest time and whether it was given a pretreatment step. They found that location wasn't important, but the other two factors could significantly increase the amount of...
