Population Dynamics


Due to our project being based around taking a section of our bacterial population, and making them sporulate, but not germinate again, we need to make sure that we do not kill off our entire population. Thus we need to be able to tune our system, so that we can have a large enough percentage of metal sequestering spores to make a positive environmental impact, but also a small enough percentage, so that the population will continue to live and grow.

Novelty in this sub-project

The novel part of this sub-project is to model the dynamics of a bacterial population, on the cellular level, as well as integrating this agent based model with biochemical models. Furthermore our simulation is able to run on distributed systems, making use of a large number of computers at once.


See Population Modelling

This section of the project is a model, which describes a high level working of our complete system. It also includes detail from other models, as it uses these in its descision making processes. The model is being developed in the Java programming language.

Other Presentations and Diagrams

For the population simulation we will be looking at a simplified model of a bacteria's life cycle.

A simplified normal life cycle may be:

Whereas our modified life cycle would have an additional state, where some spores cannot germinate. Notice that cells can enter the Metal Spore stage, but not exit it:
