Effects of terrein on cellular c-di-GMP. (a and b) Cellular c-di-GMP levels in biofilm cells of PAO1 cultured with different terrein or furanone C-30 concentrations for 9 h. After the biofilms were dissociated from the wells by gentle sonication, cellular c-di-GMP was extracted from the biofilm cells, measured, and normalized to the total proteins. (c and d) Comparison of biofilm formation by the P. aeruginosa wspF mutant versus wild-type PA14 cells cultured with different terrein or furanone C-30 concentrations for 9 h. Three independent experiments were performed in triplicate, and the mean ± SD values are displayed in each bar. *P < 0.01; **P < 0.001; ***P < 0.0001 versus DMSO treatment.
