Transformed Saccharomyces cerevisiae having improved productivity of bio-ethanol and use thereof

摘要

The present invention is a recombinant vector, the recombinant vector containing the NABH558 gene represented by AGAG1 gene sequence and SEQ ID NO: 3 shown in AGAH71 gene sequence, SEQ ID NO: 2 as shown in SEQ ID NO: 1, for building a single enzyme saccharification and fermentation systems Bioethanol through a single enzyme saccharification and fermentation system using the transformed Saccharomyces cerevisiae strain and the transformed Saccharomyces cerevisiae strain with improved bioethanol production capability including It provides a method of manufacturing. In the case of producing ethanol from agarose through the recombinant Saccharomyces cerevisiae strain of the present invention, pretreatment of biomass (substrate) is not required, and the saccharification and fermentation processes are unified to achieve unity of the process. By presenting the possibility of simplification, it can be applied to various fields of producing ethanol from biomass.
