摘要： Provided are a Corynebacterium glutamicum variant with improved L-lysine producing ability and a method of producing L-lysine using the same. The variant increases or enhances the expression of a gene encoding aspartate aminotransferase, thereby improving a production yield of L-lysine, as compared to a parent strain.

摘要： The present invention relates to a Corynebacterium glutamicum variant having an improved L-lysine production ability, and a method for producing L-lysine by using same. The Corynebacterium glutamicum variant increases or enhances the expression of a gene encoding diaminopimelate decarboxylase, and thus can have a L-lysine production yield superior to that of a parental strain.

摘要： The present disclosure relates to a Corynebacterium glutamicum mutant strain having enhanced L-lysine productivity and a method of producing L-lysine using the same. The mutant strain may produce L-lysine in an improved yield due to increased or enhanced expression of the gene encoding pyruvate carboxylase, compared to a parent strain thereof.

摘要： Provided are a Corynebacterium glutamicum variant with improved L-lysine producing ability and a method of producing L-lysine using the same. The variant increases or enhances the expression of a gene encoding transketolase, thereby improving a production yield of L-lysine, as compared to a parent strain.
