Patent ID: 8389249

Claim:
A method for producing an L-amino acid, comprising: A) culturing a bacterium belonging to the Enterobacteriaceae family in a medium comprising a fatty acid or a hydrolysate of an oil-and-fat, to produce and accumulate L-amino acid in the medium or the bacterium; and B) collecting the L-amino acid from the medium or from the bacterium, wherein said bacterium has an enhanced ability to use a fatty acid, and has an L-amino acid-producing ability, wherein said ability to use a fatty acid is enhanced by the method selected from the group consisting of: a) increasing expression of a gene selected from the group consisting of fadI, fadJ, fadL, fadE, fadD, fadB, fadA, and combinations thereof, b) attenuating expression of fadR gene or disrupting the gene, and c) increasing expression of cyoABCDE operon, and wherein said fadI, fadJ, fadL, fade, fadD, fadB, fadA and fadR genes, and cyoABCDE operon are from Escherichia coli .
