摘要
PROBLEM TO BE SOLVED: To provide a breeding method of sake yeast having lower succinic acid productivity used for producing sake which is easy to drink and has a refreshing after taste.SOLUTION: A breeding method comprises using a sake yeast having cycloheximide sensitivity as a parent strain, and selecting a strain which has lower acidity and lower succinic acid productivity, and has the same malate productivity or more as compared with the parent strain from strains cultured in a selective medium containing L-azetidine-2-carboxylic acid, without mutation treatment. The sake yeast is at least one selected from Kyokai yeast No.9, Kyokai yeast No.901, and Kyokai yeast No.701.
