Abstract
The present invention provides a method for producing an L-amino acid such as a branched-chain L-amino acid by fermentation using a bacterium of the family Enterobacteriaceae, particularly a bacterium belonging to the genus Escherichia, which has been modified to attenuate expression of the gshA gene.
Claims11
A method for producing an L-amino acid comprising:
- (i) cultivating an L-amino acid-producing bacterium of the family Enterobacteriaceae in a culture medium to produce the L-amino acid in the culture medium, the bacterium, or both;
- and
- (ii) collecting said L-amino acid from the culture medium, the bacterium, or both, wherein said bacterium has been modified to attenuate expression of a gshA gene, and wherein said L-amino acid is a branched-chain L-amino acid.
