英文摘要	Quorum-sensing inhibitor (QSI) is one of the most promising and environmentally friendly agents for marine antifouling. In this study, the activities of three kinds of QSIs 3,4-dibromo-2(5)H-furanone, 4-nitropyridine-N-oxide and indole were evaluated on the growth of two marine diatoms Cylinthrotheca sp. and Nitzschia closterium. At the same time, the effects of QSIs on the formation of the diatom-biofilm were also discussed. All the results showed that QSIs significantly inhibited the growth, and the effects depended on the dose and diatom species. The extracellular polymeric substance contents in the diatom-biofilm were significantly reduced by QSIs. However, the contents of polysaccharide in culture mediums were increased, which might result in the destruction of diatom cells. Combined with the results of crystal violet staining-biofilm and images of scanning electron microscopy, it was further demonstrated that QSIs inhibited the biofilm formation of Cylindrotheca sp., and the inhibitory effect of 4-nitropyridine-N-oxide was superior to that of 3,4-dibromo-2(5)H-furanone and indole.
