Plantaricins are antimicrobial substances composed of multiple amino acids,which have become a focus of research and attention due to their high stability,high safety,wide sources and good antibacterial effect. Plantaricins have a broad application prospect and development potential in the fields of food,livestock and poultry production,aquatic products and medicine. Unclear characteristics and low synthesis amount are one of the main reasons that limit the commercial production and application of plantaricins. In this paper,the source,antimicrobial spectra,antimicrobial mechanism,application and research of plantaricins are discussed,which has laid a certain theoretical basis for the excavation of new natural preservatives and the improvement of bacteriocin synthesis amount.
