  • Patent number: 9399784
    Abstract: The present invention relates to microorganisms of corynebacterium which can utilize xylose and to a method for producing L-lysine using same. More particularly, the present invention relates to microorganisms of corynebacterium which are modified, in which genes encoding xylose isomerase and xylulokinase which are xylose synthases are introduced to express the xylose synthase. The present invention also relates to a method for producing L-lysine, comprising a step of culturing the modified microorganisms of corynebacterium using xylose as a carbon source, and recovering L-lysine from the culture.
