Pattern Formation in Cell Cultures

Dirk Hartmann
IWR, University of Heidelberg
Germany
Colonies of Bacillus subtilis that grow on the surface of thin agar plates show various complex spatio-temporal patterns depending on environmental conditions (Wakita et al. 1994). Based on experimental observations, a new model has been constructed in the context of reaction-diffusion equations (Hartmann 2004). The model has been studied numerically as well as analytically.

Some extensions of the model for growing cell cultures, as well as limitations of existing models for growing cell cultures will be discussed.

Bio-mechanical approach for mathematical modeling of biofilms

Igor Doktorski
IWR, University of Heidelberg
Germany
Biofilms are home for the most part of existing microorganisms in the world. A recent development in the bio-catalisys is using biofilms to immobilize the catalizing bacteria. Therefore a predective model is needed.

A short overview over existing models will be given. And then a new idea of coupling mechanical properties of the single cell with the biochemistry in one continuous model will be proposed.
