Fig 2. Antimicrobial assay towards planktonic E. faecalis on agar plates.

CAP was performed for different treatment periods. Surviving colonies were counted 24 h later. All results are depicted as medians, 1^st and 3^rd quartiles from six independent experiments in duplicates on a log₁₀-scaled ordinate. Bars show the reductions of CFU in a log₁₀ scale in comparison to untreated controls. Solid and dashed lines exhibit 3 log₁₀ steps (99.9%) or 5 log₁₀ steps reduction (99.999%) of CFU, respectively. (n = 6; untreated controls exhibited 7.3 x 10¹⁰ CFU in median).
