An L-amino acid is produced by culturing a bacterium of the Enterobacteriaceae family which has an L-amino acid-producing ability in a medium containing fatty acids as the carbon source, particularly fatty acids which have been subjected to emulsification or homogenization, to thereby produce and accumulate the L-amino acid in a culture medium; and collecting the L-amino acid from the culture medium.

Method for producing an L-amino acid

A microorganism is cultured in a medium, and is able to produce one or two or more kinds of L-amino acids including L-glutamic acid, L-glutamine, L-proline, L-ornithine, L-citrulline and L-arginine, and is modified to increase &#x3b1;-ketoglutarate synthase activity. The L-amino acids are collected from the medium or the cells.
