Effect of LuxS/AI-2 Quorum Sensing System in Bacteriocin Synthesis of Lactic Acid Bacteria
Bacteriocins of lactic acid bacteria have the advantages of broad antibacterial spectrum,high stability and high safety,making them highly favored as new biological preservatives.However,the amount of bacteriocins used in industrial application currently is limited,and low synthesis amount is an important reason for their limited application.Domestic and foreign studies show that co-culture with specific microorganisms is an effective method to improve the synthesis amount of bacteriocins of lactic acid bacteria,and the process is regulated by LuxS/AI-2 quorum sensing system.In this paper,the composition of LuxS/AI-2 quorum sensing system and the effect of LuxS/AI-2 quorum sensing system in the bacteriocin synthesis of lactic acid bacteria are discussed,which has provided a certain theoretical basis for the improvement of the bacteriocin synthesis amount of lactic acid bacteria and the realization of industrial application.
