ABSTRACT:
L-Arginine is produced by culturing a microorganism which has L-arginine producing ability and has been modified so that expression of lysE gene should be enhanced, such a microorganism further modified so that an arginine repressor should not function normally, or such a microorganism further modified so that intracellular activity of an enzyme in L-arginine biosynthetic pathway should be enhanced in a medium to produce and accumulate L-arginine in the medium and collecting the L-arginine from the medium.
