FIG 1.
Representative dispersion responses of biofilms by P. aeruginosa PAO1 and the polysaccharide-overproducing strains PAO1::PBAD-pel and PAO1::PBAD-psl after exposure to glutamate (A) or nitric oxide (B). Sodium nitroprusside served as a source of nitric oxide. Biofilms were grown for 5 days in 5-fold-diluted VBMM in tube reactors. The absorbance of biofilm tube reactor effluents after the induction of dispersion is shown. Dispersion assays were performed at least three times, with each biological replicate consisting of four technical replicates, but only representative dispersion profiles are shown.
