Abstract

Provided is a highly efficient ethanol-fermentative yeast having high efficiency in ethanol production without introducing a foreign gene. The highly efficient ethanol-fermentative yeast is a fermentative yeast that effectively produces ethanol from pentose and hexose and is deposited to NITE Patent Microorganisms Depositary under the accession number NITE BP-01962.

First claim

1 . A highly efficient ethanol-fermentative yeast, the fermentative yeast effectively producing ethanol from pentose and hexose,
wherein the fermentative yeast is deposited to NITE Patent Microorganisms Depositary under the accession number NITE BP-01962.

2 . The highly efficient ethanol-fermentative yeast according to claim 1 , having ethanol fermentation performance improved by performing habituation of strain N of Meyerozyma guilliermondii in culture in a medium in which a mutagen is added to an enzymatically saccharified liquid derived from rice straw treated with ammonia and selecting yeast growing in the medium.
