  • Publication number: 20160177321
    Abstract: Disclosed herein is a process for producing a recombinant yeast cell, which includes providing a parent yeast cell that can produce ethanol by consuming a hexose and a pentose, and subjecting the parent yeast cell to a genetic modification treatment. The genetic modification treatment includes deleting, disrupting, or disabling the fps1 gene of the parent yeast cell, introducing a gene encoding xylitol dehydrogenase (XDH) into the genome of the parent yeast cell for over-production of XDH, and deleting, disrupting, or disabling the gpd1 and gpd2 genes of the parent yeast cell in a sequential order.
