This review summarizes the synthesis and regulation mechanisms of quorum sensing (QS) systems in Gram-negative and Gram-positive bacteria, focusing on key signalling molecules including acyl-homoserine lactones (AHLs), autoinducing peptides (AIPs), and autoinducer-2 (AI-2), as well as their applications in environmental remediation. The results demonstrate that QS-mediated regulation of bacterial collective behaviors primarily involves two critical processes: synthesis/release of signalling molecules and subsequent recognition-triggered behavioral responses. Notably, S-adenosylmethionine (SAM) serves as a common substrate for multiple QS signal biosynthesis pathways, potentially reflecting co-evolutionary adaptation between QS systems and bacterial coordination. Certain signalling molecules exhibit cross-kingdom functionality, not only adjusting conspecific bacterial behaviors but also mediating communication between phylogenetically unrelated bacteria and plants. Microbial communities leverage QS to synchronize population-level activities, optimize community architecture, and modulate synthesis of key degradation enzymes, thereby enhancing biofilm-mediated remediation efficiency. Finally, the development directions of QS-based microbial remediation technologies are discussed. The research results provide theoretical foundations and practical insights for studies on microbial remediation technologies.
