ABSTRACT
A L-arginine-producing mutant UN100-12(SG~(r),AE~(r)) was derived from Corynebacterium glutamicum ATCC138761 by combination treatment with ultraviolet(UV) and N-methyl-N-nitro-N-nitrosoguanidine(NTG). It could accumulate 16.6g/L L-arginine in the medium containing glucose as carbon source and ammonium sulfate as nitrogen source, when it was culrured at 30℃ for 4 days. And also this mutant has good stability of descendiblity of L-arginine.
