摘  要:
In this paper, four pairs of primers were designed for the arginine biosynthetic argCJBDFR gene clusters amplification from C.crenatum A.S 1.542 and C. crenatum A.S.M2, respectively. The mutation genes:argJ, argB and argF from C.crenatum A.S.M2 were compared with those from C.crenatum A.S 1.542 on bioinformatics, and were analyzed for the possible contribution to enhance the arginine production. These results will offer useful information and instruction to improve strains by gene engineering.
