(A) Baseline and after 24 h pH of the spent media in the treatment of LRG with A-SF, B-SF, and respective controls. (B) The buffer capacity of added buffers (Arg/NaF) for the treatment of LRG with A-SF, B-SF, and respective controls at baseline immediately after treatment. (C) The buffer capacity of added buffers (Arg/NaF) for the treatment of LRG with A-SF, B-SF, and respective controls after 24 h of treatment. (D) The biofilm pH colorimetric indicator assay performed in a 96-well microplate for LRG treated with A-SF, B-SF, and respective controls after 24 h of LRG growth to biofilm against HEPES buffer pH standards treated with pH indicator as a reference for qualitative assessment. Different lowercase (a–f)/uppercase (A–F) English alphabets and numbers (1–5) indicate significant differences between treatment groups at p < 0.05.
