Figure 1. Electrophoretic mobility vs. pH profiles of Streptococcus mutans (A), Lactobacillus casei (B), Lactobacillus salivarius (C), Lactobacillus fermentum (D), and HAP (E) in 0.01 mol L^–1 KNO₃. [Ca ²⁺] = 0 (O), 5 x 10^–4 ( ${diamondsuit}$ ), 1 x 10^–3 ( ${blacktriangleup}$ ), and 1 x 10^–2 ( ${blacktriangledown}$ ) mol/L. Also shown in (A) and (C), measurements in the presence of natural saliva: [Ca²⁺] = 1 x 10^–2 mol L^–1 ( ${square}$ ); [Ca²⁺] = 0 ( ${diamond}$ ). Vertical bars indicate SD of triplicate experiments.
