PROBLEM TO BE SOLVED: To provide a method for classifying yeast strains into strain groups which are different by important characteristics on fermented soybean paste and soy sauce brewing industry, according to the difference in the base sequence information of various yeast strains.SOLUTION: The invention provides a discrimination method of yeast strains in which a yeast strain group separated from fermented soybean paste/soy sauce (products) and unfinished products in brewing steps thereof and the like is classified into [1] Zygosaccharomyces rouxii strain and yeast strains except [2] Zygosaccharomyces rouxii using, as an indicator, the presence or absence of base sequence parts corresponding to the base sequence from position 1132454 to position 1133788 which comprises the base sequence parts having high similarity to a partial base sequence on plasmid pSR1 on chromosome C of Zygosaccharomyces rouxii CBS732 strain; and an inspection method of fermented soybean paste/soy sauce (products) and an unfinished product thereof using the discrimination method. |
