Abstract
The present invention relates to the production of biofuels and chemical feedstocks. The present invention provides recombinant yeast having enhanced xylose fermentation capabilities. Methods of using such recombinant yeast for improved biofuel and chemical feedstock production are also provided.
Claims24
A recombinant yeast that has been genetically engineered to exhibit reduced amounts of functional Isu1 polypeptide, wherein the genetically engineered recombinant yeast is capable of increased aerobic xylose fermentation relative to a wild-type yeast or another recombinant yeast not exhibiting reduced amounts of functional Isu1 polypeptide.
A recombinant yeast that has been genetically engineered to exhibit reduced amounts of functional Isu1 and Hog1 polypeptides, and at least one of functional Gre3, Ira1, and Ira2 polypeptides, wherein the genetically engineered recombinant yeast is capable of increased anaerobic xylose fermentation relative to a wild-type yeast or another recombinant yeast not exhibiting reduced amounts of functional Isu1 and Hog1 polypeptides, and at least one of functional Gre3, Ira1, and Ira2 polypeptides.
