title: [Phage resistance of Corynebacterium crenatum conferred by the restriction and modification system cglI].
abstract: In order to prevent phage contamination in amino acid fermentation, we introduced the restriction and modification system cglI gene complex into Corynebacterium crenatum and studied their phage-resistance. The cglI gene complex was amplified from Corynebacterium glutamicum by PCR and constructed into pJL23 vector. The recombinant strains were obtained by transformation of the recombinant plasmid pJL23-cglI into C. crenatum. Results showed that the recombinant strains possessed strong phage-resistance activity and broad phage-resistance spectrum, demonstrating the feasibility of using cglI gene complex for construction of phage-resistance recombinant C. crenatum strains and presenting a powerful way to solve the problem of phage contamination in amino acid fermentation industry.
