Study casts doubt on climate benefit of biofuels from corn residue
Using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline, according to a study published today in the journal Nature Climate Change.
Team uses cellulosic biofuels byproduct to increase ethanol yield
Scientists report in Nature Communications that they have engineered yeast to consume acetic acid, a previously unwanted byproduct of the process of converting plant leaves, stems and other tissues into b ...
Scientists overcome major obstacles to cellulosic biofuel production
A newly engineered yeast strain can simultaneously consume two types of sugar from plants to produce ethanol, researchers report. The sugars are glucose, a six-carbon sugar that is relatively easy to ferment; ...
Microbes to Take Over Ethanol Production?
Tiny super-plant can clean up animal waste, be used for ethanol production
Researchers at North Carolina State University have found that a tiny aquatic plant can be used to clean up animal waste at industrial hog farms and potentially be part of the answer for the global energy ...
Yeast uses CO2 to boost bioethanol production
Introducing four genes from bacteria and spinach has enabled researchers at the Delft University of Technology to improve the production of bioethanol with yeast by using carbon dioxide. Their findings were ...
New yeast strain could lower costs for cellulosic ethanol production
There's a lot that can be done with a corn cob after the kernels have been removed. Farmers leave the cobs on the field to boost soil quality. Enterprising cooks use the cobs to make jelly. In China, the ...
Photovoltaics beat biofuels at converting sun's energy to miles driven
In 2005, President George W. Bush and American corn farmers saw corn ethanol as a promising fossil fuel substitute that would reduce both American dependence on foreign oil and greenhouse gas emissions. Accordingly, the 2005 ...
US 'extreme drought' zones triple in size
The drought in America's breadbasket is intensifying at an unprecedented rate, experts warned, driving concern food prices could soar if crops in the world's key producer are decimated.
Researchers upgrade ethanol to a better fuel
(Phys.org) -- At Cornell, researchers are turning beer into biofuel.
New study explores proteins in Yellowstone bacteria for biofuel inspiration
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.
Air pollution results from sugarcane ethanol production
(PhysOrg.com) -- The burning of sugarcane fields prior to harvest for ethanol production can create air pollution that detracts from the biofuel's overall sustainability, according to research published recently ...
Study questions cost-effectiveness of biofuels and their ability to cut fossil fuel use
A new study by economists at Oregon State University questions the cost-effectiveness of biofuels and says they would barely reduce fossil fuel use and would likely increase greenhouse gas emissions.
Second-generation ethanol processing cost prohibitive: study
Costs for second-generation ethanol processing, which will ease the stress on corn and sugarcane, are unlikely to be competitive until 2020, according to a unique Queen's University study.
