Peptide Mix from Olivancillaria hiatula Interferes with Cell-to-Cell Communication in Pseudomonas aeruginosa

Figure 4

Antibiofilm activity of peptide mix. Micrographs of P. aeruginosa biofilm on glass slides: (a) untreated control showing dense biofilm in the absence of peptide, (b) biofilm inhibition in the presence of 1/2 MIC of peptide mix, and (c) disruption of preformed biofilm treated with 2.5 mg/mL of peptide mix. (d) Antibiofilm effect of peptide concentration on Pseudomonas aeruginosa. Each bar represents mean ± SD of triplicate experiments in a microtiter plate-based assay.
