Abstract Provided is a method for producing ethanol with high efficiency through the ethanol fermentation from xylose using a saccharified biomass that contains various fermentation-inhibiting substances. A method for producing ethanol from a biomass according to the present invention comprises the steps of mixing xylose-utilizing yeast that has been so transformed as to over-express a gene for an acetic acid response transcription factor with a saccharified biomass and then culturing the yeast. La présente invention concerne un procédé de production d'éthanol à haut rendement par le biais de la fermentation de l'éthanol à partir de xylose à l'aide d'une biomasse saccharifiée qui contient diverses substances inhibant la fermentation. Le procédé de production d'éthanol à partir d'une biomasse selon la présente invention comprend les étapes consistant à mélanger une levure utilisant le xylose qui a été transformée de façon à sur-exprimer un gène d'un facteur de transcription de réponse de l'acide acétique avec une biomasse saccharifiée puis à cultiver la levure.
