摘要: 乳酸菌生物膜是乳酸菌为了应对不良环境而聚集形成的一种状态,在许多情况下乳酸菌都是以生物膜的形式存在,因此有必要加深对乳酸菌生物膜的了解和研究。本文综述了乳酸菌生物膜的形成,碳源、金属离子、pH值、抗生素、有害菌和非生物表面对乳酸菌生物膜的影响,以及多种基因对乳酸菌生物膜的调控作用,并介绍了乳酸菌生物膜在食品抑菌和发酵中的应用情况,以期为乳酸菌生物膜今后的形成调控研究和在食品工业中的应用提供参考。

Abstract: The biofilm represents a state in which lactic acid bacteria gather in order to cope with adverse environment. In many cases, lactic acid bacteria exist in the form of biofilm. Hence, it is necessary to deeply understand and study lactic acid bacteria biofilm. This article reviews the formation of lactic acid bacteria biofilms, the effects of carbon sources, metal ions, pH, antibiotics, harmful bacteria, and abiotic surfaces on lactic acid bacteria biofilms and the various genes regulating lactic acid bacteria biofilms, and it summarizes the application of lactic acid bacteria biofilm in food preservation and fermentation, hoping to provide a reference for studies on the formation and regulation of lactic acid bacteria biofilm and its application in the food industry in the future.

Key words: lactic acid bacteria; biofilm; regulation mechanism; application
