MUTANT YEAST STRAIN WITH DECREASED GLYCEROL PRODUCTION

摘要

The present invention relates to the use of a mutant SSK1 gene encoding a truncated ssk1protein for the construction of a mutant yeast strain with decreased glycerol production, when compared to the wild type strain. It relates further to the use of such strains for high yield bioethanol production, especially in high osmotic media, or on cellulosic hydrolysates, where normal yeast strains do produce a significant amount of glycerol.
