The present invention provides a method for producing an amino acid
selected from the group consisting of L-alanine, L-valine, L-leucine,
L-isoleucine, L-methionine, L-phenylalanine, L-proline, glycine,
L-serine, L-threonine, L-cysteine, L-tyrosine, L-asparagine, L-glutamine,
L-lysine, L-histidine, L-arginine, L-aspartic acid and L-glutamic acid
and useful as medicament, chemical agent, food material and feed additive
at high industrial efficiency, the method comprising culturing a
microorganism having an ability to produce the amino acid and having
resistance to an aminoquinoline derivative in a medium, producing and
accumulating the amino acid in the present invention in the culture, and
recovering the amino acid from the culture.
