Summary of the percent reduction of P. aeruginosa (PAO1) biofilm biomass following 24 h challenge using sterile 72 h KS8 supernatant during biofilm formation and on mature, pre-established 24 h P. aeruginosa (PAO1) biofilms (biofilm removal assay). Differences in mean absorbance compared to the untreated control of each time-point were 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.
