ETHANOL PRODUCTION BY MUTANT YEAST

摘要

The invention relates to methods of producing ethanol and yeast cells that may be used according to the method. Said method comprising growing respiratory deficient yeast cells (such as K1 DELTA pet191ab described herein) which have at least one nuclear gene, or product thereof, required for respiration which is non-functional and/or inhibited in a growth medium. The method may be used in the production of fuel ethanol or for the production of alcoholic drinks.
