细菌素的分子生物学研究进展

摘要

Bacteriocins are a heterogeneous group of ribosomally synthesized antibacterial peptides or protein from some bacteria species. They are expected to become alternatives of food additives and antibiotics for their broad-spectrum antimicrobial activity, This paper reviews the bacteriocins molecular structure and function, genotyping, biosynthesis and their gene regulation, mode of antibacterial action and bacteria species of bacteriocin producing.%细菌素作为细菌合成的蛋白质(多肽)类抑菌物质,其广谱的抗菌活性,有望成为食品添加剂以及抗生素的替代品.主要对细菌素的分类及其作用机制、细菌素的生物合成及其调控,以及细菌素产生菌加以阐述.
