Abstract: The biofilm structure of Listeria monocytogenes endows this bacterium with high antimicrobial resistance, making it difficult to effectively remove its biofilm during food processing. Quorum sensing (QS) is closely related to physiological characteristics of bacteria, such as biofilm formation, virulence invasiveness and stress response. In this article, the characteristics of L. monocytogenes biofilm are summarized. Emphasis is put on the formation mechanism from the perspective of quorum sensing (autoinducer-2 system and autoinducing peptide system). The currently available approaches for controlling L. monocytogenes biofilm are reviewed as well as studies on plant extracts as quorum sensing inhibitors. The aim of this review is to provide new ideas for the prevention and control of biofilm formation of L. monocytogenes.

Key words: Listeria monocytogenes, biofilm, quorum sensing, auto-inducing factors, plant extracts
