More ethanol-tolerant yeast for more biofuel production

Yeast is an important component in the ethanol production process; however, high concentrations of ethanol are toxic to yeast. In order to improve the ethanol production process, researchers from the Massachusetts Institute of Technology are working to boost yeast tolerance to ethanol. “Toxicity is probably the single most important problem in cost-effective biofuels production,” said George Stephanopoulos, the Willard Henry Dow Profes...
