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 α-ketoglutarate synthase activity. The L-amino acids are collected from the medium or the cells.
