OVER EXPRESSION OF RIBONUCLEOTIDE REDUCTASE INHIBITOR IN YEAST FOR INCREASED ETHANOL PRODUCTION

摘要

Described are compositions and methods relating to modified yeast that over-express the ribonucleotide reductase inhibitor, HUG1. The yeast produces an increased amount of alcohol compared to parental cells. Such yeast is particularly useful for large-scale ethanol production from starch substrates where acetate in an undesirable end product.
