  • METHOD FOR PRODUCTION OF SUBSTANCE IN CANDIDA UTILIS USING XYLOSE AS CARBON SOURCE
    Publication number: 20120045803
    Abstract: Disclosed is a yeast strain of Candida utilis, wherein the yeast strain has been transformed with at least one of three genes that are operatively linked to a promoter sequence and encode polypeptides having activities of xylose reductase, xylitol dehydrogenase, and xylulose kinase. The yeast strain is useful for producing a metabolic product from xylose with high efficiency.
