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
