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.
