Green Tech America creates new yeast

By | June 03, 2009
Green Tech America Inc. has produced a new type of yeast that the company believes will help generate cellulosic ethanol more cost-effectively. Nancy Ho, founder and president of Green Tech and a research professor at Purdue University's School of Chemical Engineering in the Laboratory of Renewable Resources Engineering and the Energy Center, developed a yeast to help efficiently produce ethanol from cellulosic biomass feedstocks. The yeast ferments glucose and xylose; conventional yeasts only ferment glucose. Green Tech, which is based in the Purdue Research Park, has received and optioned for an exclusive license for improvements to the new yeast. The research has been funded by a number of entities, including the U.S. DOE.
