Abstract

Quorum sensing-regulated microbial behaviors often negatively impact wastewater treatment, leading to issues such as biofouling in membrane bioreactors, filamentous bulking, and resistance gene transfer. Quorum quenching, which counteracts quorum sensing, offers a promising strategy to mitigate these problems. This review aims to highlight overlooked perspectives for its application in microbial aggregates during wastewater treatment. First, the review examines the quorum sensing network present in microbial aggregates and the regulatory role of different quorum sensing systems in bacterial function and behavior during wastewater treatment. The discussions cover hierarchical, parallel, and competitive quorum sensing systems to clarify the interactions among these pathways. A precise quorum quenching strategy is proposed to enhance efficiency based on the type of quorum sensing regulation. Additionally, a bridge is established between the physiological characteristics of quorum quenching bacteria and process parameters to achieve process control over bacterial function and behavior during wastewater treatment.

在废水处理过程中，微生物聚集体群体猝灭的潜在作用。

群体感应调节的微生物行为通常会对废水处理产生负面影响，导致膜生物反应器中的生物污染、丝状膨胀和抗性基因转移等问题。抵消群体感应的群体淬灭为缓解这些问题提供了一种很有前途的策略。本文综述了其在废水处理中微生物聚集体中的应用前景。首先，本文研究了微生物聚集体中存在的群体感应网络，以及不同群体感应系统在废水处理过程中对细菌功能和行为的调节作用。讨论涵盖层次，平行和竞争群体感应系统，以澄清这些途径之间的相互作用。根据群体感应调节的类型，提出了一种精确的群体淬灭策略来提高效率。此外，在群体猝灭菌的生理特性和工艺参数之间建立了一座桥梁，以实现对废水处理过程中细菌功能和行为的过程控制。
