Quorum sensing (QS) is a system of cell-to-cell communication by means of intercellular signalling molecules to coordinate a set of targeted gene expression or repression in many Gram-negative bacteria; it plays important roles for bacteria in adaptation to adverse environmental conditions. In this study, we first demonstrated that Microcystis aeruginosa PCC-7820 could produce QS-related signal acylated homoserine lactones (AHLs) among the metabolite of axenic M. aeruginosa, based on bioassay and liquid chromatography - mass spectrometry (LC-MS) analysis. The concentration of the AHLs in the culture medium was cell density-dependent and reached a maximum of 18 nM at 1.03 × 10(7) cells mL(-1) , 30 days after inoculation. The regulation mechanism of QS in M. aeruginosa and its possible role in bloom formation are discussed. © 2012 Federation of European Microbiological Societies. Published by Blackwell Publishing Ltd.
