Understanding the microbial communications opens a new horizon in the exploration of biological systems, including membrane bioreactors (MBRs). Microbial group behaviors (e.g., biofilm formation), induced by quorum sensing (QS) using signal molecules, cause severe MBR membrane biofouling. To tackle such phenomena, inactivation of signal molecules has been implemented as a new antibiofouling strategy, which is called quorum quenching (QQ). This chapter covers the mechanisms of QS and QQ as well as several different QQ approaches using enzymes, chemical compounds, and microorganisms (e.g., bacteria and fungi) in the MBRs. Various methods to develop and apply the biomedia encapsulating QQ microorganisms for MBR fouling mitigation have been reviewed. Recent information on microbial community and diversity, which can be affected by QS and QQ, was also collected and discussed.
