German yeast catalyst improves yield

By | April 15, 2010
German-based biofuels producer Butalco will use a new yeast catalyst technology to produce cellulosic ethanol. The yeast advancements ferment C5 waste sugars making the production of ethanol cheaper and more efficient, increasing production yields up to 30 percent, according to the company. Starting this summer, Butalco will test the process under industrial level conditions at a Hohenheim University pilot facility. "Together with the new commercially viable enzymes launched by Danisco and Novozymes, our yeast technology will enable cellulosic ethanol [to be] a competitive alternative to gasoline," said Eckhard Boles, co-founder of Butalco. The Hohenheim plant is the only facility in Germany that allows genetically modified yeasts, Boles noted.
