Research progress in quorum sensing and quorum quenching in the interaction between microalgae and bacteria

Abstract:

Quorum sensing is a communication mechanism between microbial populations. By recognizing signal molecules, microorganisms can exchange information within and outside the population and regulate their physiological behaviors. Quorum quenching can block quorum sensing by interrupting the synthesis, secretion, and recognition of quorum-sensing signal molecules. In the interaction process between microalgae and bacteria, quorum sensing and quorum quenching jointly regulates the physiological changes in microalgae and bacteria for their balanced coexistence. This paper introduces the occurrence process and detection of quorum sensing and elaborates on the role of quorum sensing in the interaction between microalgae and bacteria. Furthermore, this paper expounds the occurrence mechanism of quorum quenching and the performance and ecological benefits of quorum quenching in the interaction between microalgae and bacteria. Finally, prospects are put forward for studying the mechanism of the interaction between microalgae and bacteria and the role of the interaction in marine ecosystems.
