Membrane biofouling is widely acknowledged as the most frequent adverse event in wastewater treatment systems resulting in significant loss of treatment efficiency and economy. Different strategies including physical cleaning and use of antimicrobial chemicals or antibiotics have been tried for reducing membrane biofouling. Such traditional practices are aimed to eradicate biofilms or kill the bacteria involved, but the greater efficacy in membrane performance would be achieved by inhibiting biofouling without interfering with bacterial growth. As a result, the search for environmental friendly non-antibiotic antifouling strategies has received much greater attention among scientific community. The use of quorum quenching natural compounds and enzymes will be a potential approach for control of membrane biofouling. This approach has previously proven useful in diseases and membrane biofouling control by triggering the expression of desired phenotypes. In view of this, the present review is provided to give the updated information on quorum quenching compounds and elucidate the significance of quorum sensing inhibition in control of membrane biofouling.
膜生物污染被广泛认为是废水处理系统中最常见的不良事件，会导致处理效率和经济性的显著损失。人们尝试了包括物理清洗以及使用抗菌化学品或抗生素在内的不同策略来减少膜生物污染。此类传统做法旨在根除生物膜或杀死相关细菌，但通过在不干扰细菌生长的情况下抑制生物污染，可在膜性能方面取得更高的成效。因此，寻找环境友好型非抗生素防污策略在科学界受到了更多关注。使用群体感应淬灭天然化合物和酶将是控制膜生物污染的一种潜在方法。这种方法先前已被证明在疾病防治和膜生物污染控制方面通过触发所需表型的表达而有用。有鉴于此，本综述旨在提供关于群体感应淬灭化合物的最新信息，并阐明群体感应抑制在控制膜生物污染中的重要性。
