Isoamyl alcohol and isoamyl acetate high-producing yeast strains, screening methods thereof, and methods of using these strains

摘要

PPROBLEM TO BE SOLVED: To provide a method for screening a yeast strain highly producing isoamyl alcohol and/or isoamyl acetate; to provide a method for readily and efficiently producing the isoamyl alcohol and/or the isoamyl acetate; and to provide the yeast strain highly producing the isoamyl alcohol and/or the isoamyl acetate. PSOLUTION: The yeast capable of proliferating under 10-100 MPa pressure is selected by culturing the yeast under the pressure, or the yeast capable of proliferating at 4-17C is selected by culturing the yeast at the temperature. The obtained strain capable of highly producing the isoamyl alcohol and/or the isoamyl acetate is cultured to produce the isoamyl alcohol and/or the isoamyl acetate by the yeast strain.
