摘要

Quorum sensing (QS) regulates bacterial behaviors such as biofilm formation, virulence, and metabolite production through signaling molecules like acyl-homoserine lactones (AHLs), peptides, and AI-2. These signals are pivotal in bacterial communication, influencing pathogenicity and industrial applications. This review explores the molecular architecture of QS signals and their role in metabolite production, emphasizing structural modifications that disrupt bacterial communication to control virulence and enhance industrial processes. Key findings highlight the development of synthetic QS analogs, engineered inhibitors, and microbial consortia as innovative tools in biotechnology and medicine. The review underscores the potential of molecular engineering in managing microbial behaviors and optimizing applications like biofuel production, bioplastics, and anti-virulence therapies. Additionally, cross-species signaling mechanisms, particularly involving AI-2, reveal new opportunities for regulating interspecies cooperation and competition. This synthesis aims to bridge molecular insights with practical applications, showcasing how QS-based technologies can drive advancements in microbial biotechnology and therapeutic strategies.
