FIG. 3.

Effects of phage PM2 infection on TPP⁺ (A), PCB⁻ (B), and K⁺ (C) ion uptake by different Pseudoalteromonas strains. The experiments were carried out at 28°C in 50 mM Tris-HCl (pH 8.0)-450 mM NaCl-10 mM CaCl₂ with a cell concentration of 2 × 10⁹ CFU/ml. ER72M2 (curve 1) cells were infected with an MOI of 10, and BAL-31 (curve 2) and A28 (curve 3) cells were infected with an MOI of 50. A second infection of ER72M2 cells (curve 1) was carried out using an MOI of 50. GD and PMB were added at final concentrations of 5 and 100 μg/ml, respectively.
