Title : Method for producing ethanol from xylose
Patent No. US 8628944 B2
Issued Date: Jan. 1, 2014
Inventor : Jin-Ho Seo and Yong-Cheol Park

Abstract
Disclosed is a method for producing ethanol from xylose using a recombinant Saccharomyces cerevisiae strain transformed to express a xylose reductase that uses NADH as a cofactor and a xylitol dehydrogenase that uses NAD+ as a cofactor, which are coupled with each other. The method provides an increase in ethanol yield and production efficiency, as compared to a control group, and enables production of ethanol at higher yield and high production efficiency by further eliminating acetaldehyde dehydrogenase which mediates production of acetic acid (by-product).
