Antimicrobial action of nisin against Salmonella typhimurium lipopolysaccharide mutants
Article Abstract:
The antimicrobial effect of nisin on lipopolysaccharide (LPS) mutants of Salmonella typhimurium was examined. Parental strains were found insensitive to the antibiotic, although LPS mutants exhibited nisin sensitivity. The results indicate that the core oligosaccharide in the LPS of the outer membrane plays a role in the resistance of S. typhimurium to nisin. The findings also suggest that the spectrum of nisin may be extended to gram-negative bacteria by altering the outer cell membrane by mutations or by chemical treatment with chelating agents.
