Effect of polyP3 on the growth of the bacteria at a high inoculum density. Each bacterial strain cultured to exponential phase was adjusted to approximately 10⁸ cells/ml in B-HK, then exposed to polyP3 at various concentrations. The bacterial growth was measured by reading optical density at 600 nm (OD₆₀₀) after the 24-hour incubation. Data are means ± SDs from two independent experiments performed in triplicate. One-way ANOVA with Tukey’s post-hoc tests p < 0.001, versus control (0% polyP3).
