Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce the concentration of acetic acid by metabolizing acetic acid in the medium upon xylose assimilation in yeast having a xylose-metabolizing capacity and ethanol fermentation.SOLUTION: A production method for ethanol comprises a step for performing ethanol fermentation by culturing, in a medium containing xylose, recombined yeast into which a xylose isomerase gene and an acetaldehyde dehydrogenase gene have been introduced.
