MOYENS POUR REDUIRE L'ACCUMULATION D'ACETOINE DANS DES MILIEUX DE FERMENTATION ALCOOLIQUE

摘要

The invention relates to yeasts expressing the gene BDH1 coding for Bdh1p, characterized in that they catalyze, in an alcoholic fermentation medium, the reduction of acetoin into 2,3-butanediol by a rate at least twice higher than that of the initial stem. The invention can particularly be used for the fermentation of fruit juice and for producing 2,3-butanediol.
