摘要:
The present invention relates to a gene encoding a catalase and use thereof, in particular, a brewery yeast having high sulfite-producing capability, alcoholic beverages produced with said yeast, and a method for producing said beverages. More particularly, the present invention relates to a yeast, whose capability of producing sulfite, that contribute to stability of flavor in products, is enhanced by amplifying expression level of CTT1 gene encoding a catalase Ctt1p, especially non-ScCTT1 gene or ScCTT1 gene specific to a lager brewing yeast, and to a method for producing alcoholic beverages with said yeast.
摘要:
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 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.
摘要:
It is intended to provide a method of identifying a gene of a yeast for brewing which participates in the flavor of an alcoholic drink and control the expression of this gene to thereby enable the production of an alcoholic drink having a desirable flavor. To achieve the above object, a method of identifying a yeast for brewing by using a gene analysis means comprising a DNA array optionally together with two-dimensional electrophoresis, a DNA array having the thus identified gene attached thereto, and a method of selecting a yeast for brewing with the use of this DNA array are provided.
摘要:
The present invention relates to ammonia transporter genes and use thereof. The invention relates in particular to a brewer's yeast which shows enhanced ammonia assimilation, alcoholic beverages produced using such yeast, and a method of producing such alcoholic beverages. More specifically, the invention relates to the MEP1 gene which codes for the ammonia transporter Mep1 in brewer's yeast, particularly to a yeast which can control the ammonia assimilation ability by controlling the level of expression of the nonScMEP1 gene or ScMEP1 gene characteristic to beer yeast and to a method of producing alcoholic beverages using such yeast.
摘要:
The present invention relates to a gene encoding a protein having a trehalose synthesis-promoting activity and use thereof, in particular, a yeast for practical use with superior resistance property to dryness and/or low-temperature storage, alcoholic beverages produced with said yeast, and a method for producing said beverages. More particularly, the present invention relates to a yeast, whose resistance property to dryness and/or resistance property to low-temperature storage is enhanced by amplifying expression level of TSL1 gene encoding a protein Tsl1p having a trehalose synthesis-promoting activity in brewer's yeast, especially non-ScTSL1 gene specific to a lager brewing yeast and to a method for producing alcoholic beverages with said yeast, etc.
摘要:
The present invention relates to a glycerol channel gene and its uses, specifically, a brewery yeast producing alcoholic beverages with excellent body and mellowness, alcoholic beverages produced using the yeast, a process for producing the alcoholic beverages. More particularly, the present invention relates to a yeast whose capability of producing glycerol, which contribute to body and mellowness of products, was controlled by controlling expression level of FPS1 gene encoding brewery yeast glycerol channel Fps1p, particularly non-ScFPS1 gene specific to lager brewing yeast, and to a method for producing alcoholic beverages with the yeast.
摘要:
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.
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.
