(A) Scanning Electron Microscopy Biofilm Imaging (×8000, 15 kV) for LRG treated with A-SF, B-SF, and respective controls: (a) LRG; (b) 1% Arg; (c) 2% Arg; (d) 0.2% NaF; (e) 1% Arg + 0.2% NaF; and (f) 2% Arg + 0.2% NaF. (B) Bacterial weight (in gms) determined for LRG treated with A-SF, B-SF, and respective controls. (C) Biofilm F content (in µg/g) determined for LRG treated with A-SF, B-SF, and respective controls. (D) Biofilm amine content (in µg/g) determined for LRG treated with A-SF, B-SF, and respective controls. (E) Lactic acid generated in the spent media after 24 h treatment of LRG with A-SF, B-SF, and respective controls. Different lowercase (a–e) English alphabets indicate significant differences between treatment groups at p < 0.05.
