摘 要: | 生物污染是水处理膜分离应用面临的主要问题之一。生物膜的形成受细菌群体感应系统调控,群体感应抑制是控制膜生物污染的新兴技术。介绍了群体感应机制及其参与生物膜形成的有关研究。通过干扰和阻断细菌的信息交流通路,可阻止群体感应依赖型基因表达从而抑制细菌的特定群体行为。综述了基于细菌群体感应和群体淬灭的水处理膜生物污染控制研究,考察了各类群体感应抑制剂在膜法水处理系统中的应用,以及抑制剂固定化、膜材料改性等研究进展,展望了群体感应理论在膜生物污染控制中的研究方向。

Abstract: | Biofouling is a critical challenge in the membrane-based water treatment process. Biofilm formation is regulated by bacterial quorum sensing. Inhibition of quorum sensing is an emerging technology for membrane biofouling control. Mechanism of quorum sensing and research on biofilm formation involving quorum sensing was introduced in this work. By interfering with and blocking the circuits of cell-cell communication, expression of the target quorum-sensing-controlled gene can be prevented, and the specific group behavior of bacteria can be inhibited. Research on biofouling control of water treatment membranes based on quorum sensing and quorum quenching is reviewed. The application of quorum sensing inhibitors in membrane-based water treatment systems, and studies on the immobilization of inhibitors as well as membrane modification are overviewed. An outlook of future research on membrane biofouling control based on quorum sensing tactics is proposed. |
