Biofuels pioneer Mascoma LLC and the Department of Energy's BioEnergy Science Center have developed a revolutionary strain of yeast that could help significantly accelerate the development of biofuels from nonfood plant matter.

The approach could provide a pathway to eventual expansion of biofuels production beyond the current output limited to ethanol derived from corn.

C5 FUEL™, engineered by researchers at Mascoma and BESC, features fermentation and ethanol yields that set a new standard for conversion of biomass sugars from pretreated corn stover -- the non-edible portion of corn crops such as the stalk -- converting up to 97 percent of the plant sugars into fuel.
