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.

Abstract: Disclosed herein are a transformed Synechococcus elongatus strain having improved capability of producing acetone and a method for producing acetone and a method for removing carbon dioxide using the same. In an aspect, the transformed Synechococcus elongatus strain of the present disclosure can produce acetone with high selectivity using carbon dioxide as a carbon source. The present disclosure is economical because the Synechococcus elongatus strain can economically produce high value-added acetone using carbon dioxide existing in the atmosphere as a carbon source without requiring an additional catalytic reaction. Also, the present disclosure is environment-friendly because carbon dioxide in the atmosphere can be removed or reduced using the microorganism.
