Genes Related to Xylose Fermentation and Methods of Using Same for Enhanced Biofuel Production

摘要

The present invention provides isolated gene sequences involved in xylose fermentation and related recombinant yeast which are useful in methods of enhanced biofuel production, particularly ethanol production. Methods of bioengineering recombinant yeast useful for biofuel production are also provided.

主权项

1. An isolated nucleic acid having: (a) the nucleotide sequence of SEQ ID NO:2 or SEQ ID NO:3; or (b) a nucleotide sequence which hybridizes under stringent conditions to SEQ ID NO:2 or SEQ ID NO:3, or to a fully complementary nucleotide sequence thereof, wherein over-expression in yeast of said isolated nucleic acid provides increased xylose fermentation in the yeast relative to a control yeast lacking over-expression of the isolated nucleic acid.
