群体感应和群体淬灭在藻菌互作中的功能研究进展

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

摘要:

群体感应是微生物群体之间的一种交流机制。根据信号分子的识别，微生物可以进行种群内以及种群间的信息交流，并调控自身的生理行为。而群体淬灭可以通过打断群体感应信号分子的合成、分泌与识别进程，从而阻断群体感应。在微藻和细菌的互作过程中，群体感应和群体淬灭的共同作用调控着微藻和细菌的生理变化，使得它们达成生态平衡而共存。本文综述了群体感应的发生过程与检测，并阐述群体感应在微藻和细菌互作中的作用。同时，论述了群体淬灭的发生机制，并探讨群体淬灭在微藻和细菌互作中的作用与生态效益。以期为更全面地了解藻菌关系的复杂联系、进一步揭示藻菌互作的分子机制及在海洋生态系统中的作用提供借鉴。

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.
