FIGURE 2.

Growth kinetic experiment. (a) Schematic diagram illustrating a bacterial growth experiment performed in drug‐free media separately for PB and PF populations. We used an absorbance microplate reader to measure the optical density (OD₆₃₀) at different time‐points during the 24‐h experiment. (b) Growth curves of PB (green) and PF (black) strains, with replicate experiments represented as shaded curves. The duration of the exponential phase, σ, was estimated by identifying the start of exponential phase and the time elapsed before reaching carrying capacity. Parameter ρ refers to the maximum growth rate of the PB population, while the selective advantage of the PF strain is represented with r.
