ABSTRACT In this study, the impact of exogenous N-acyl-homoserine lactones (AHLs) on greenhouse gas (GHG) emissions in anaerobic/anoxic/oxic (A/A/O) systems was analyzed by manipulating type and dosage AHLs. The mechanism behind AHLs’ effects GHG explored through changes microbial community structure. Findings revealed that N-octanoyl-homoserine lactone (C8-HSL) high-dose N-dodecanoyl-homoserine (C12-HSL) increased emissions, while low-dose C12-HSL decreased them. Moreover, C8-HSL promoted...
