Super-yeast generates ethanol from energy crops and agricultural residues

A new type of baker's yeast (Saccharomyces cerevisiae) has been developed which can efficiently ferment pentose sugars, as found in agricultural waste and hardwoods. In a new study, researchers describe the creation of the new S. cerevisiae strain, TMB3130, which demonstrated significantly improved aerobic growth rate and final biomass concentration on sugar media composed of two pentoses, xylose and arabinose.
