The time of formation and rate of bacterial population waves as a function of substrate concentration has been investigated. It was shown both theoretically and in experiment that the time of wave formation increases with substrate concentration. At the same time, the rate of wave propagation decreases at relatively high substrate concentrations. A comparative analysis of the dynamics of bacterial population waves in different chemotaxis responses was carried out in in silico experiments with the Keller-Segel model.
