    摘要: PROBLEM TO BE SOLVED: To provide a method for increasing the amino acid content of an alcoholic beverage (especially wine), or a method for increasing the γ- aminobutyric acid of such an alcoholic beverage. SOLUTION: This method for producing an alcoholic beverage, especially wine, comprises using a yeast mutant for alcoholic beverage production belonging to the genus Saccharomyces and having gap1, apf1 (shr3) and can1 as the mutations in a gene involved in amino acid intake, a yeast mutant for alcoholic beverage production belonging to the genus Saccharomyces and having gap1, put4 and uga4 as the mutations in a gene involved in amino acid intake, or a yeast mutant for alcoholic beverage production belonging to the genus Saccharomyces and having gap1, apf1 (shr3), can1, put4 and uga4 as the mutations in a gene involved in amino acid intake.

    摘要: PROBLEM TO BE SOLVED: To stably obtain a mutant yeast capable of suppressing the intake of amino acid by yeast and increasing the amino acid content by using a strain belonging to the genus Saccharomyces and having variations of gap1 and apf1(shr3) as the variation of gene participating in the intake of amino acid. SOLUTION: The objective yeast is Saccharomyces cerevisiae MA2504 (FERM 17407) belonging to the genus Saccharomyces and containing variations of gap1 and apf1(shr3) as the variation of gene participating in the intake of amino acid. The yeast is preferably Saccharomyces cerevisiae MA2601 (FERM P-17408) belonging to the genus Saccharomyces and containing variations of gap1 and can1 as the variation of gene participating in the intake of amino acid. Wine or a malt alcoholic drink is produced by using these mutant yeasts for the production of liquor.
