PROCESS FOR PRODUCING L-GLUTAMIC ACID

摘要

A process for producing L-glutamic acid, comprising culturing coryneform bacteria capable of L-glutamic acid production in a culture medium so as to attain formation and accumulation of L-glutamic acid in a culturing product and collecting L-glutamic acid from the culturing product, wherein use is made of coryneform bacteria modified so as to increase the activity of the following protein: (A) protein having an amino acid sequence of SEQ ID No. 2, or (B) protein composed of an amino acid sequence of SEQ ID No. 2 having undergone substitution, deletion, insertion or addition of one or some amino acids, which protein when introduced in coryneform bacteria, exhibits the activity of enhancing the potency for L-glutamic acid production.
