ABSTRACT:
An L-amino acid-producing strain ofEscherichia coliis bred by modifying anEscherichia coliK12 strain or a derivative thereof so as to become resistant to L-valine and have an ability to produce one or more L-amino acids selected from the group consisting of L-tryptophan, L-phenylalanine, L-lysine, L-tyrosine, L-glutamic acid, L-histidine, L-cysteine, and L-proline.
