Commercial yeasts upgraded with an enzyme for biofuel production
Date:2/24/2009

This release is available in German.

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.

In industrial fermentation processes, the yeast Saccharomyces cerevisiae is commonly used for ethanol production. Current bioethanol production technologies can use only parts of the plants, namely the storage sugars, like glucose, sucrose or starch. However, this technology is in competition with food and feed production. Eckhard Boles, co-founder of the Swiss biofuel company Butalco GmbH and a professor at Goethe-University in Frankfurt, Germany, has therefore searched for ways of teaching the microorganisms to convert waste sugars, xylose and arabinose, into ethanol. Now, Boles and his colleagues have succeeded in genetically modifying industrial yeast strains, thus producing ethanol from xylose in a single step. Having already succeeded in transforming arabinose into ethanol by genetically modified yeast strains, Boles and his team have now found an efficient way to convert most of the plants energy into biofuel.

"Up to now scientists considered it as unpromising to equip yeast with a bacterial enzyme capable of converting xylose", Boles explains, "because all attempts had failed". But he and his team continued trying by exploring the enormous amounts of information in current genetic databases. Step by step they took 12 enzymes from different bacterial organisms and inserted the enzymes into yeast cells. Finally they discovered a new enzyme that even worked in yeast cells from a commercial ethanol plant. In contrast to current cellu
