Abstract:

As food safety issues are increasingly valued by the international community,the application of bacteriocins that target food spoilage/pathogenic bacteria has received great attention. As a safe natural preservative,bacteriocin can effectively resist food-borne pathogens through different modes of action,like pore formation and inhibition of cell-wall/nucleic acid/protein synthesis. However,emergence and spread of mutant strains resistant to bacteriocins is hampering food safety. More and more people have begun to know the phenomenon of food pathogens resistances to bacteriocins,and this is conducive for people to have the deep study of bacteriocin drug-resistance. This article reviews the classification,synthesis,antibacterial mechanism,and production methods of bacteriocins,introduces the mechanism of bacterial resistance to bacteriocin and the methods of reducing bacteriocin resistance to drug,and further clarifies the potential application of bacteriocin as a natural preservative in food preservation.

Key words: bacteriocins, classification, antibacterial mechanism, drug resistance, food preservation
