Research Progress of Microbial Quorum Sensing in Waste water Biological Treatment
Quorum sensing(QS),known as the language of intercellular communication is a gene regulatory system that relies on colony density.It is found in many natural and wastewater treatment engineering systems and plays an important role in environmental remediation and wastewater biotreatment.At present,there is a lack of systematic summary of the research methods and related applications of QS regulating bacterial function.In this paper,the QS mechanism mediated by three types of typical signal molecules(N-Acyl homoserine 1 actones,autoinducing peptides and furanosyl borate diEnvironmental Science & Technologyer)of bacteria was summarized.The three techniques of adding or quenching signal molecules,genetic manipulation of genes,and omics techniques to study the function of the QS system were reviewed,and their advantages and disadvantages were compared and analyzed.The application of QS in activated sludge,biofilm and biological nitrogen removal in the field of industrial wastewater biological treatment was discussed.Finally,combined with the current application potential of QS cross-border communication in wastewater treatment and the limitations of known research contents,some studies on QS system-mediated bacterial-plant,bacterial-phage,bacterial-fungal cross-border communication mechanisms were discussed,in order to provide new ideas for using QS regulation strategies to enhance wastewater treatment efficiency in the future.
