Absorbance at 595 nm of crystal violet-stained biofilms. Biomass of biofilms (of all 40 isolates and ATCC 15692) as measured by absorbance at 595 nm of crystal violet-stained biofilms after treatment with: (A) 10⁷ PFU/mL phage treatments or growth media control for 24 h, (B) 10⁸ PFU/mL phage treatments or growth media control for 24 h, (C) 10⁷ PFU/mL phage treatments or growth media control for 48 h, (D) 10⁸ PFU/mL phage treatments or growth media control for 48 h. Boxplot whiskers represent range (minimum to maximum values). (NB: nutrient broth; ^**p < 0.01; ^***p < 0.001).
