Figure 3.

Experimental and simulated total (X) and persistent (p) populations in an antibiotic‐free batch culture with the different switching models. The initial substrate concentration used is 4.0 g l⁻¹. The experimental data plotted is the mean of the three experiments performed with 4.0 g l⁻¹ glucose. The switching model selected barely affects the dynamic of the total population. The switching models principally differ by the behaviour of the persistent population in the first five hours of the batch culture.
