YEAST STRAIN HAVING HIGH PRODUCTIVITY OF BETA-PHENETYL ALCOHOL AND BETA-PHENETYL ACETATE, ITS BREEDING METHOD, AND PRODUCTION OF LIQUORS USING THE SAME YEAST

摘要

PURPOSE:To efficiently separate the title yeast useful for producing liquors having excellent sweet smell from a specific analog resistant strain by separating the analog resistant strain from a yeast belonging to Saccharomyces cerevisiae. CONSTITUTION:A yeast belonging to Saccharomyces cerevisiae is, as necessary, treated with a variant-inducing treatment and then an analog resistant variant which became proliferative even in a culture medium containing an analog of phenylalanine of a high concentration incapable of normally growing is separated from the yeast. Then a strain capable of producing beta-phenetyl alcohol and beta-phenetyl acetate at remarkable amounts is separated from the resist variant to provide the objective yeast [e.g. Saccharomyces cerevisiae Kyokai 7-FPAR 18 (FERM P-10868)].
