  • Patent number: 8628944
    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).
