Abstract
Official abstract text for this publication.
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
Opening claim text (preview).
The invention claimed is: 1. A highly efficient ethanol-fermentative yeast, the fermentative yeast effectively producing ethanol from pentose and hexose, wherein the fermentative yeast has xylose utilization and ethanol fermentation performance improved, in comparison with a wild strain of Meyerozyma guilliermondii , by performing habituation of the wild strain 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, the mutagen including any one of an ethylating agent, a base analog and a nitroso compound, and selecting yeasts growing in the medium and wherein the fermentative yeast is deposited to National Institute of Technology and Evaluation (NITE) Patent Microorganisms Depositary under the accession number NITE BP-01962. 2. An ethanol-fermentative yeast deposited to National Institute of Technology and Evaluation (NITE) Patent Microorganisms Depositary under accession number NITE ABP-01962.
