Biofilm prevention assay. 24 h biofilm biomass (mean absorbance of biomass at 590 nm) of P. aeruginosa PAO1 (green) following 24 h exposure to 100 μL of sterile 3-day supernatants of marine isolates ABP4, LL53, LL67, KS6, KS8, JUN4, ISO1, ISO2, ISO4. CM = Conditioned media. Differences in mean absorbance were compared to the untreated control at each time-point and considered significant when p < 0.05 (* p < 0.05, ** p < 0.01, *** p < 0.001) according to the non-parametric Kruskal Wallis test with Dunn’s Multiple Comparison Test.
