Abstract
Official abstract text for this publication.
An object of the present invention is to obtain a fermentative yeast having a highly efficient ethanol production without introducing a foreign gene. A further object is to obtain a fermentative yeast that is resistant to proliferation inhibitors such as organic acids, which prevent the proliferation of the fermentative yeast. A yeast having an improved ethanol production ability was generated by introducing transaldolase and alcohol dehydrogenase genes by self-cloning to Meyerozyma guilliermondii that can produce ethanol effectively from pentose and hexose obtained by breeding, and further breeding the resultant yeast.
First claim
Opening claim text (preview).
The invention claimed is: 1. A highly efficient ethanol-fermentative yeast, the ethanol-fermentative yeast effectively producing ethanol from pentose and hexose, wherein the ethanol-fermentative yeast is a fermentative yeast having xylose utilization ability in a corn stover sugar solution improved by breeding a yeast deposited to National Institute of Technology (NITE) Patent Microorganisms Depositary under the accession number NITE ABP-01976 in a corn stover sugar solution, and wherein the fermentative yeast is deposited to NITE Patent Microorganisms Depositary under the accession number NITE BP-01966. 2. An ethanol-fermentative yeast deposited to National Institute of Technology and Evaluation (NITE) Patent Microorganisms Depositary under accession number NITE ABP-01966.
