Abstract: The present specification relates to a transformed yeast strain capable of simultaneously utilizing xylose and glucose as carbon sources, a preparation method thereof and a biofuel production method using the same. The transformed yeast strain transforms a wild-type yeast strain incapable of using xylose as a carbon source and simultaneously convert glucose and xylose, thereby enabling high yield production of a biofuel. The economics and sustainability of the biofuel and biomaterial production processes can be highly enhanced by providing a strain which can easily be converted to a strain capable of producing a biofuel/material in a high yield through an additional modification.

Abstract: Disclosed herein are a yeast strain capable of utilizing xylose as a carbon source and a method for producing lipids using the same. The yeast strain is obtained by adaptively evolving a wild-type yeast strain which cannot utilize xylose as a carbon source so that it can produce high density lipids and then transforming the adaptively evolved strain to obtain the ability to metabolize xylose. Since the strain does not have the xylose metabolic pathway based on oxidoreductase, it can produce biodiesel and biomaterials based on lipid and lignocellulosic biomass at a high yield without a problem of cofactor imbalance and can greatly improve the economic feasibility and sustainability of the production processes of biodiesel and biomaterials.
