Abstract

A study was made of the time of formation and the rate of propagation of bacterial population waves as dependent on substrate concentration. Experimentally and theoretically it is shown that the time of bacterial wave formation grows with increasing concentration of the nutritive component. At the same time, the wave propagation rate drops at relatively high concentrations of the nutritive component. In numerical experiments with a mathematical model, comparative analysis has been made of the dynamics of the behavior of bacterial waves at different chemotactic responses.
