Inhibition on S. mutans MT8148 grown by the S-PRG eluate. (A,B) Bacterial growth by adding varying concentration of the eluate followed by 18 h incubation. Growth was determined by OD₅₅₀ values in BHI broth (A) and recovered bacterial numbers on MSB plates (B). (C) Bacterial growth by adding 1 × 10⁷ CFU/ml of S. mutans at multiple time points, which was determined by OD₅₅₀ values in BHI broth. (D) Bacterial survival by adding 1 × 10⁷ CFU/ml of S. mutans at multiple time points, which was determined by adding serial dilutions of the bacterial suspensions to MSB plates.
