Mathematical Modeling Overview
A complex mathematical model of E. lemming from both literature inspired and self developed submodels was created that covers the processes displayed in Figure 1.
In a first step, existing models for the individual processes of E. lemming have been identified by literature research, implemented, corrected and adapted to our needs. Where we could not rely on established models, we started modeling on our own and calibrating the model with regard to available literature knowledge.
- Light Switch: both implementation approaches have been modeled:
- PhyB/PIF3: a deterministic molecular model based on the light-sensitive dimerizing Arabidopsis proteins PhyB and PIF3.
- Archeal Light Receptor: a deterministic molecular model based on the archeal light receptor.
- Chemotaxis Pathway: two deterministic molecular models of the chemotaxis pathway.
- Bacterial Movement: a self developed stochastic model of E. coli movement on basis of the CheYp bias.
Secondly we combined the submodels stepwise to more comprehensive models that we could use to address different important questions to:
- Light switch - Chemotaxis: this model was used to reduce wet laboratory experiments by identify molecular targets by experimental design.
- Light switch - Chemotaxis - Movement: complete model of E. lemming as a simulative test bench for the controller design and as a brick of the comprehensive simulation of information processing.
