METHOD FOR PRODUCING ETHANOL FROM XYLOSE USING RECOMBINANT SACCHAROMYCES CEREVISIAE INVOLVING COUPLED USE OF NADH AND NAD+

摘要

Disclosed is a method for producing ethanol from xylose using recombinant Saccharomycescerevisiae. In accordance with the method, NADH as a cofactor of xylose reductase required for the ethanol production, and NAD+ as a cofactor of xylitol dehydrogenase are coupled with each other and utilized, and acetaldehyde dehydrogenase mediating production of acetic acid as a byproduct is removed, and ethanol can thus be produced at a high yield and high production ef ficiency.
