The motility of B.Subtilis is hypothesised to be affected by various levels of EpsE expression. In order to model motility as a function of EpsE production, we have decided to use video microscopy techniques to analyse the motility of B.Subtilis. We hope to obtain a transfer function model relating EpsE expression to bacterial motility characteristics such as run velocity, run duration, tumbling angle and tumbling duration. This modelling process is shown on the right and has been divided into 3 main sections:
Several alternative models were created for the purpose of model fitting. The motility data obtained is then analysed and fitted to alternative models. Preferences will then be assigned to fitted models using probabilistic methods such as Bayesian Analysis.
