STRAIN FOR HIGHLY PRODUCING ISOAMYL ACETATE AND METHOD FOR BREEDING THE SAME, AND RICE WINES USING STRAIN FOR HIGHLY PRODUCING ISOAMYL ACETATE AND METHOD FOR PRODUCING THE SAME

摘要

PPROBLEM TO BE SOLVED: To obtain brewing yeast that highly produces isoamyl acetate and rice wines having a high E/A ratio and to provide a method for producing fragrant liquors by using the brewing yeast. PSOLUTION: Yeast highly producing isoamyl acetate in high frequency is obtained by selecting a variant exhibiting resistance to hygromycin B. Fragrant rice wine containing isoamyl acetate at a high concentration is stably produced by using the variant without requiring a cost, time and labor. PCOPYRIGHT: (C)2007,JPO&INPIT
