  • MUTANT OF CORYNEBACTERIUM GLUTAMICUM WITH ENHANCED L-CITRULLINE PRODUCTIVITY AND METHOD FOR PREPARING L-CITRULLINE USING THE SAME
    Publication number: 20240150801
    Abstract: The present invention relates to a Corynebacterium glutamicum mutant strain having increased L-citrulline productivity, and a method of producing L-citrulline using the same. The Corynebacterium glutamicum mutant strain is capable of producing L-citrulline in high yield and high concentration while inhibiting the production of by-products, because the activity of the protein that is expressed by the NCgl2657 gene therein has been weakened or inactivated.

  • MICROORGANISM OF CORYNEBACTERIUM GENUS HAVING ENHANCED L-ARGININE OR L-CITRULLINE PRODUCTIVITY AND A METHOD FOR PRODUCING L-ARGININE OR L-CITRULLINE USING THE SAME
    Publication number: 20240026283
    Abstract: The present disclosure relates to a Corynebacterium sp. mutant strain having increased L-arginine or L-citrulline productivity and a method of producing L-arginine or L-citrulline using the same. The Corynebacterium sp. mutant strain has enhanced activity of acetylornithine aminotransferase involved in the L-arginine biosynthesis pathway, and thus is capable of producing L-arginine or L-citrulline productivity in an increased yield compared to a parent strain.

    Publication number: 20240026282
    Abstract: The present disclosure relates to a Corynebacterium sp. mutant strain having increased L-arginine or L-citrulline productivity and a method of producing L-arginine or L-citrulline using the same. The Corynebacterium sp. mutant strain has enhanced activity of acetylglutamate kinase involved in the L-arginine biosynthesis pathway, and thus is capable of producing L-arginine or L-citrulline in an increased yield compared to a parent strain.
