Abstract
The present invention provides an industrially efficient method for producing an L-amino acid useful as medicament, chemical agent, food material and feed additive, and the method comprising culturing in a medium a microorganism having an ability to produce the L-amino acid and having resistance to a DNA gyrase inhibitor or a microorganism having an ability to produce the L-amino acid and having both resistance to a DNA gyrase inhibitor and resistance to an aminoquinoline derivative, producing and accumulating the L-amino acid therein and recovering the L-amino acid therefrom.

A method for producing an L-amino acid, which comprises:
- (a) culturing in a medium a microorganism having an ability to produce an L-amino acid and having resistance to a DNA gyrase inhibitor;
- (b) producing and accumulating the L-amino acid in the culture;
- and
- (c) recovering the L-amino acid from the culture.
A microorganism having an ability to produce an L-amino acid and having resistance to a DNA gyrase inhibitor.
A microorganism selected from either Escherichia coli H-9342 (FERM BP-6675) or Escherichia coli H-9343 (FERM BP- 6676).
