Biofuels pioneer Mascoma LLC and the U.S. 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.

BESC is led by Oak Ridge National Laboratory.

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.

Researchers studying more effective ways to convert woody plant matter into biofuels at Oak Ridge National Laboratory have identified fundamental forces that change plant structures during pretreatment processes used in the production of bioenergy.

The research team, which published its results in Green Chemistry, set out to decipher the inner workings of plant cell walls during pretreatment, the most expensive stage of biofuel production. Pretreatment subjects plant material to extremely high temperature and pressure to break apart the protective gel of lignin and hemicellulose that surrounds sugary cellulose fibers. [Read more…]
