The present invention relates to a brewery yeast having controlled hydrogen sulfide-producing capability, a process for producing alcoholic beverages with controlled hydrogen sulfide amount. More particularly, the present invention relates to a yeast whose hydrogen sulfide-producing capability that increases the product flavor is controlled by enhancing the expression level of MET17 gene encoding brewery yeast O-acetylhomoserinesulfhydorelace Met17p, particularly non-ScMET17 gene specific to lager brewing yeast, and to a method for producing alcoholic beverages with said yeast.
L'invention concerne une levure de bière présentant une capacité de production de sulfure d'hydrogène commandée, un procédé de production de boissons alcooliques possédant une quantité de sulfure d'hydrogène commandée. Plus précisément, l'invention concerne une levure dont la capacité de production de sulfure d'hydrogène accroissant le goût du produit est commandée par accroissement du niveau d'expression du gène MET17 codant Met17p d'O-acétylhomosérinesulfhydorélace de la levure de bière, notamment le gène non-ScMET17 spécifique de la levure de bière lager et un procédé de production de boissons alcooliques mettant en oeuvre cette levure.
