Highlights Opportunity to Reduce America's Oil Dependence and Create Jobs in Rural America
U.S. Energy Secretary Steven Chu today (3/11/11) congratulated a team of researchers at the Department's BioEnergy Science Center who have achieved yet another advance in the drive toward next generation biofuels: using bacteria to convert plant matter directly into isobutanol, which can be burned in regular car engines with a heat value higher than ethanol and similar to gasoline. This research is part of a broad portfolio of work the Department is doing to reduce America's dependence on foreign oil and create new economic opportunities for rural America.
"Today's announcement is yet another sign of the rapid progress we are making in developing the next generation of biofuels that can help reduce our oil dependence," said Secretary Chu. "This is a perfect example of the promising opportunity we have to create a major new industry - one based on bio-material such as wheat and rice straw, corn stover, lumber wastes, and plants specifically developed for bio-fuel production that require far less fertilizer and other energy inputs. But we must continue with an aggressive research and development effort."
Secretary Chu added that: "America's oil dependence -- which leaves hardworking families at the mercy of global oil markets - won't be solved overnight. But the remarkable advance of science and biotechnology in the past decade puts us on the precipice of a revolution in biofuels. In fact, biotechnologies, and the biological sciences that provide the underlying foundation, are some of the most rapidly developing areas in science and technology today - and the United States is leading the way. In the coming years, we can expect dramatic breakthroughs that will allow us to produce the clean energy we need right here at home. We need to act aggressively to seize this opportunity and win the future."
BACKGROUND ON THE SCIENTIFIC ADVANCE ANNOUNCED TODAY
The work was conducted by researchers at the Department of Energy's BioEnergy Science Center (BESC), led by Oak Ridge National Laboratory. Using consolidated bioprocessing, a research team led by James Liao of the University of California at Los Angeles for the first time produced isobutanol directly from cellulose. The team's work, published online in Applied and Environmental Microbiology, represents across-the-board savings in processing costs and time, plus isobutanol is a higher grade of alcohol than ethanol.

"Plus, it may be possible to use isobutanol directly in current engines without modification."
