Mean and standard deviations from four independent experiments are shown. Asterisks indicate significant differences using ANOVA with Tukey’s post-hoc test (***p < 0.001). There was no difference in cytotoxicity between Mock and predatory bacteria. PA14 indicates P. aeruginosa strain PA14, Mica = M. aeruginosavorus, HD100 and 109J indicate B. bacteriovorus strains. (A) 4 h, (B) 24 h.
