The L-amino acid-producing E. coli mutant strain and Corynebacterium glutamicum mutant strain according to the present disclosure exhibit an enhanced ability to produce L-amino acid, such as L-tryptophan, L-phenylalanine, L-tyrosine, L-glutamine, L-lysine, L-arginine, L-valine, L-leucine, L-isoleucine, L-threonine, L-histidine, L-serine, or L-citrulline, compared to parent strains thereof, and are capable of producing a high concentration of L-amino acid in high yield.

Abstract: The present disclosure relates to a mutant strain having enhanced L-glutamic acid productivity and a method of producing L-glutamic acid using the same. The mutant strain according to one embodiment of the present disclosure has reduced production of citramalate as a by-product due to weakening or inactivation of the activity of citramalate synthase and has excellent L-glutamic acid productivity. The strain having an additional mutation in the YggB protein may produce L-glutamic acid in an improved yield due to enhancement of glutamic acid release. Thus, when the mutant strain is used, it is possible to more effectively produce L-glutamic acid.
