We introduce a single-cell based simulation model of biofilm growth. Each microbial cell is modelled as an autonomous agent whose behavior is controlled by thermodynamic parameters, mechanical properties, physiological rules and environmental conditions. In the two-dimensional version presented...

Brownian forces have a nonnegligible effect on the motion of small microorganisms (sizes of the order of the μ or smaller). Starting from the model for the motion of Brownian objects with internal energy depots recently proposed by Schweitzer et al. (Phys. Rev. Lett. 80 (1998) 5044) (SET), we...
