Process could improve economics of ethanol production
(PhysOrg.com) -- Iowa State University's Hans van Leeuwen has moved his research team's award-winning idea for improving ethanol production from a laboratory to a pilot plant.
Wine yeasts reveal prehistoric microbial world
However, one of the most well-known characteristics of yeast is the ability of Saccharomyces cerevisiae, baker's yeast, to ferment sugar to 2-carbon components, in particular ethanol, without completely oxidising it to car ...
Surging food prices fuel ethanol critics
A surge in global food prices has prompted fresh criticism of US subsidies for ethanol, which diverts massive amounts of corn from global food supplies for energy.
Penn State ag economist says rising food prices not the farmers' fault
Wholesale food prices rose last month by the most in 36 years, and experts can't say how high they'll ultimately go. As the effects appear everywhere from the supermarket to fast food restaurants, an economist ...
Bioenergy crops could lower surface temperatures: research
(PhysOrg.com) -- Converting large swaths of farmland to perennial grasses for biofuels could lower regional surface temperatures, according to a recent Stanford study.
Enzymes from garden compost could favour bioethanol production
Today, bioethanol is primarily made from glucose. If xylose -- which is found in straw, willow and other fast-growing plant species -- could also be used efficiently, then ethanol production could increase significantly. ...
Alcohol consumption after age 75 associated with lower risk of developing dementia
3202 German individuals (75+) attending general practitioners , who were free of dementia were studied at baseline, were followed up 1.5 years and 3 years later by means of structured clinical interviews including detailed ...
BESC scores a first with isobutanol directly from cellulose
In the quest for inexpensive biofuels, cellulose proved no match for a bioprocessing strategy and genetically engineered microbe developed by researchers at the Department of Energy's BioEnergy Science Center.
Researchers demonstrate use of proteins as raw material for biofuels, biorefining
Two types of raw materials are currently used for biorefining and biofuel production: carbohydrates and lipids. Biofuels like ethanol are derived from carbohydrate raw materials such as sugars and lignocellulose, while biodiesels ...
Sugarcane bioethanol: Environmental implications
An article in the current issue of Global Change Biology Bioenergy assessed the net greenhouse gas savings of bioethanol from sugarcane as compared to the use of fossil fuels.
Turning bacteria into butanol biofuel factories
(PhysOrg.com) -- While ethanol is today's major biofuel, researchers aim to produce fuels more like gasoline. Butanol is the primary candidate, now produced primarily by Clostridium bacteria. UC Berkeley chemist ...
Overfertilizing corn undermines ethanol
Rice University scientists and their colleagues have found that when growing corn crops for ethanol, more means less.
The green machine: Algae clean wastewater, convert to biodiesel
Let algae do the dirty work. Researchers at Rochester Institute of Technology are developing biodiesel from microalgae grown in wastewater. The project is doubly "green" because algae consume nitrates and phosphates and reduce ...
The evolution of ethanol: Promising new research goes beyond corn
Fueling up your car with ethanol produced from blue-green algae may sound far-fetched. But Bill Gibbons, a professor and researcher in SDSUs Department of Biology and Microbiology, says it is close to reality ...
