Document Type and Number:
WIPO Patent Application WO/2023/104005
Kind Code:
A1
Abstract:
Provided is an ester-producing yeast strain, wherein the yeast is a Pichia kudriavzevii C4.12 strain, of which the preservation number is CCTCC NO: M 2021124. Also provided are a microbial agent of the yeast and a preparation method therefor, a fermentation product of the yeast, and liquor prepared using the yeast or the microbial agent. The yeast strain has the characteristics of multi-environment tolerance, broad-spectrum substrate applicability and ester production, and can improve the sensory flavor of traditional brewed products, improve product quality, and enrich product taste.
