摘要:
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.
