Beschreibung
Zusammenfassung:	The invention is intended to metabolize acetic acid in a medium at the time of culture, such as ethanol fermentation by yeast, and to reduce acetic acid concentration.　Specifically, the invention relates to a recombinant yeast resulting from introduction of the acetaldehyde dehydrogenase gene (EC 1.2.1.10) and regulation of an enzyme involved with trehalose accumulation. La présente invention vise à métaboliser l'acide acétique dans un milieu au moment de la culture, comme la fermentation de l'éthanol par la levure, et à réduire la concentration d'acide acétique. Spécifiquement, l'invention concerne une levure recombinante résultant de l'introduction du gène de l'acétaldéhyde déshydrogénase (EC 1.2.1.10) et de la régulation d'une enzyme impliquée dans l'accumulation de tréhalose.
