Mutant strain having enhanced l-glutamic acid producing ability, and l-glutamic acid preparation method using same

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.
