Abstract

Dispersion and migration of bacteria under flow in confined structures is related to a large spectrum of practical interests, and lacks a fully satisfactory understanding. We introduce a simple bidimensional continuous model trying to describe the main characteristics of the movement of E. colialong a microchannel. Their convective transport, lateral wall absorption/desorption processes and migration along lateral walls are taken into account. The model reproduces the anomalous dispersion of bacteria when passing through a constriction.
