Patent ID: 7867735

Claim:
A method for producing L-glutamic acid comprising: A) culturing a coryneform bacterium in a medium, and B) collecting L-glutamic acid from the medium, wherein said coryneform bacterium is modified so that the expression of the fasR gene is enhanced as compared to a parent strain by increasing the copy number of the gene or modifying an expression control sequence of the gene, wherein said bacterium is able to produce L-glutamic acid in a medium containing 50 μg/l or more biotin without adding a biotin activity suppressing agent selected from the group consisting of a surfactant and penicillin, and wherein the fasR gene is selected from the group consisting of: a) a DNA comprising nucleotides 506 to 976 in SEQ ID NO: 3 or nucleotides 1 to 474 in SEQ ID NO: 5, b) a DNA which is able to hybridize with nucleotides 506 to 976 in SEQ ID NO: 3, or nucleotides 1 to 474 in SEQ ID NO: 5, under stringent conditions comprising washing at 0.1×SSC, 0.1% SDS at 60° C.
