Bacteriocins produced by lactic acid bacteria are a heterogeneous group of activated peptide or proteinous material, most of which are provided with inhibition for bacteria in near relation,and the minority with wider bacteriostatic spectra. The bacteriocins mainly consist of small heat-stable petides, large heat-labile proteins and lantibiotics. Bacteriocins produced by pure lactic acid bacteria are a kind of preparation which is made from mixed powdery material of lactic acid bacteria and its metabolizability products ,they can be produced and used for medicine and food additive after skimmed milk experiences sterilization ,vacuum condense ,lactic acid bacteria fermentation and dryness ,which belong to dairy products of curative effect. The classification, mechanism of restraining growth of bacteria and application in food and medicine of bacteriocin produced by lactic acid bacteria are comprehensively and systematically reviewed in this paper, and further research and prospect of its application are given.
