MODULATING UREA DEGRADATION IN WINE YEAST.

摘要

The invention provides yeast strains transformed to reduce nitrogen catabolite repression of a gene encoding a urea degrading enzymatic activity expressed by the yeast strain under fermenting conditions. Strains ofSaccharomyces cerevisiae are for example provided having enhanced DUR1,2 urea carboxylase-allophanate hydrolase activity under wine fermenting conditions.
