METHOD FOR IMPARTING ACETIC ACID TOLERANCE, METHOD FOR PRODUCING ACETIC ACID-TOLERANT YEAST AND METHOD FOR PRODUCING ETHANOL BY USING ACETIC ACID-TOLERANT YEAST

摘要

PROBLEM TO BE SOLVED: To improve acetic acid tolerance of yeast having ethanol fermentative ability.SOLUTION: The YOL046C gene and/or a gene functionally equivalent to the YOL046C gene are introduced into yeast having ethanol fermentative ability, or the expression level of the gene in the yeast is improved.
