The Invention
UW-Madison researchers have developed a novel xylose fermenting S. cerevisiae yeast capable of converting xylose into ethanol. The researchers did an extensive analysis of xylose fermentation activity in a variety of yeast species and found that xylose reductase from Scheffersomyces xylosifermentans acted in a cofactor independent manner which means that this gene can produce ethanol from xylose under anaerobic conditions. Adding this gene into S. cerevisiae converted the yeast from one that produces xylitol under anaerobic conditions into one that produces ethanol under anaerobic conditions.
