ABSTRACT:
A microorganism is provided which has an ability to produce an L-amino acid such as L-lysine, L-tryptophan, L-phenylalanine, L-valine, L-leucine, L-isoleucine and L-serine, and has been modified to increase the activity of pyruvate synthase or pyruvate:NADP+oxidoreductase. This microorganism is cultured in a medium containing ethanol or an aliphatic acid as the carbon source to produce and accumulate the L-amino acid in the medium or cells, and the L-amino acid is collected from the medium or the cells.
