HYDRODYNAMICS OF BACTERIAL MOTION

In this paper we present a hydrodynamic approach to describe the motio n of migrating bacteria as a special class of self-propelled systems. Analytical and numerical calculations has been performed to study the behavior of our model in the turbulent-like regime and to show that a phase transition occurs as a function of noise strength. Our results c an explain previous experimental observations as well as results of nu merical simulations.
