ABSTRACT:
L-Arginine is produced by culturing a coryneform bacterium in which an arginine repressor involved in L-arginine biosynthesis is deleted by disrupting a gene coding for the repressor, and which has L-arginine producing ability in a medium to produce and accumulate L-arginine in the medium, and collecting the L-arginine from the medium.
