Abstract
The present invention provides a method for producing a basic L-amino acid, for example, L-ornithine L-citrulline, L-arginine, L-histidine, and L-lysine by fermentation using a bacterium belonging to the family Enterobacteriaceae which has been modified to overexpress a gene encoding a protein having L-methionine/branched chain amino acid exporter activity.
