Pyoverdine inhibition. (a) Relative fluorescence of pyoverdine secreted by Pseudomonas aeruginosa with and without sub-MIC doses of the peptide mix and standard drug, gentamicin. Each bar represents mean ± SD of fluorescence intensities of 3 independent experiments. (b) Percentage inhibition of pyoverdine secretion in Pseudomonas aeruginosa in the presence of sub-MIC doses of the peptide mix and gentamicin. Percentage inhibitions were computed with respect to the fluorescence of the control group. Each bar represents mean ± SD of triplicate experiments.
