Bacteriocin Synthesis of Lactic Acid Bacteria under Quorum Sensing

Abstract:

Bacteriocin is a kind of antibacterial peptide synthesized by ribosomes during the metabolism process, which is widely used in the food industry as a natural and non-toxic antibacterial agent. Quorum sensing is an act of regulating the genes expression by response to the concentration of autoinducers among the bacterial cells. The quorum sensing of lactic acid bacteria has been proved to play a key role in the bacteriocin synthesis.The current research progress of bacteriocin of lactic acid bacteria, including the systematic classification of the bacteriocin, the transduction mechanism of quorum sensing signals and the regulation of LAB bacteriocin synthesis, was reviewed in this article, aiming to give reference and inspiration to the development and application of bacteriocin.
