Bacteria use quorum sensing (QS) to regulate the formation of functional products and coordinate their activities in response to the inhabitant’s density. Microbial systems generate, release, and sense the motioning organic compounds autoinducers which are vital in the QS process. Its quantity rises with the increasing population of bacterial colonies. As soon as its concentration attains a critical level, it triggers various physicochemical activities like biofilm formation, virulence factor production, bioluminescence, etc. in an organized manner. Recently, the mechanism of QS has been extensively studied due to its technological and medical applications including combating microbial pathogenicity, biofilm-related infections, and environmental problems. In this connection, quorum quenching (QQ) has evolved to control QS processes by obstructing their key steps like signal generation, accumulation, and detection. Unlike killing bacteria using antibiotics, the QQ process controls the communication process without harming bacterial colony averts antibacterial resistance. The study of QS and QQ has huge implications for biotechnology, medicine, and environmental management.
