Review evaluates quorum sensing mechanisms and strategies for improving anaerobic treatment of saline wastewater.
Anaerobic treatment of industrial wastewater offers a sustainable and cost-effective approach to reducing environmental contamination while recovering biogas. High-salinity wastewater poses ecological risks and remains difficult to treat due to salt-induced sludge disintegration, volatile fatty acid accumulation, and reduced methane production. Quorum sensing is emerging as a key regulator of microbial activity and system stability under salt stress. This review summarizes salinity-stress inhibition mechanisms, evaluates quorum sensing-based mitigation strategies, and proposes a stage- and performance-based framework for quorum sensing application to advance resilient and efficient anaerobic treatment systems.
