Commercial yeasts upgraded with an enzyme for biofuel production
Date: 3.3.2009
**Waste sugar** xylose fermented to **ethanol** through introduction of a single step.
Eckhard Boles, co-founder of the Swiss biofuel company Butalco GmbH and a professor at Goethe-University in Frankfurt, Germany, has discovered a **new enzyme** which teaches yeast cells to ferment xylose into ethanol. **Xylose** is an unused waste sugar in the cellulosic ethanol production process. The researchers have recently filed a patent application for their process.
