Fig. 2: 4S biofilm recovery after perturbation.

Evolution of the biomass (as reported by µOD) of the 4S biofilm grown in the square channel (1 mm²) at 1 mL/h for 38 h at 30 °C, and then partially destroyed by the injection of a 200-µL bubble of air (red arrow). The bold curve shows the average of three distinct positions in the channel (light gray curves).
