R91 prevents and eradicates biofilms. Biofilm formation in the presence and absence of R91 after (A) co-incubation of R91 and Staphylococcus aureus USA300 LAC for 24 h, (B) 24 h of R91 incubation after 24 h of initial biofilm formation. Biofilms were quantified using an A₅₉₀ after crystal violet staining. %biomass was quantified by comparing the OD of the treated samples to the OD of the untreated samples. Data are shown as the mean ± SD of at least three independent experiments. ∗∗p ≤ 0.01, ∗∗∗∗p ≤ 0.0001 using a one-way ANOVA with Dunnett’s multiple comparison.
