Abstract

The present invention relates to a cysteine synthase gene and use thereof, especially 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 YGR012W gene encoding brewery yeast cysteine synthase Ygr012wp, particularly non-ScYGR012W gene specific to lager brewing yeast, and to a method for producing alcoholic beverages with said yeast.

Description

technical field

[0001] The present invention relates to a cysteine ​​synthase gene and its use, and in particular to brewer's yeast for producing alcoholic beverages with excellent aroma, alcoholic beverages produced using the yeast, and methods for producing them. More specifically, the present invention relates to a yeast that improves product aroma and uses the yeast by increasing the expression level of the gene YGR012W encoding brewer's yeast cysteine ​​synthase Ygr012wp, especially the characteristic nonScYGR012W gene or ScYGR012W gene in brewer's yeast. The production method of alcoholic beverages, etc. Background technique

[0002] Brewer's yeast used in the manufacture of commercially available pilsner type pale beer has the property of producing hydrogen sulfide during the main fermentation process. This hydrogen sulfide is one of the causes of the unfavorable tender beer taste in terms of beer quality, and measures to reduce it below a threshold value include pro...
