November 17th, 2009 (PhysOrg.com) -- Making biofuels from plants brings opportunities and challenges, according to Dr. Tim Donohue, Director of the Great Lakes Bioenergy Research Center, one of three U.S. Department of Energy Bioenergy Research Centers. The opportunity lies in the availability. Donohue gave a talk at the Pacific Northwest National Laboratory's Frontiers in Biological Sciences Seminar Series. The series features academic government and industrial leaders who discuss novel ideas and scientific advances in biological sciences.
"We're trying to replace fossil fuels in the liquid transportation fuels sector, so we have to use a readily available feedstock. Cellulose is the most abundant organic material on the planet," said Donohue. It consists largely of sugar polymers (glucose plus others) that can be converted to other fuels by catalytic or microbial chemistries. And these sugars come from the non-edible parts of the plants, rather than from food sources.
