Chemotactic bacteria rely on chemical concentration gradients to bias their motion toward attractants or away from repellents. Our work on chemotaxis (transcript) aims for a qualitative description of such motion (coauthors: Steven Presse, Hossein Jashnsaz).

 

The .gif below shows one iteration of the model for a uniformly distributed population of bacteria near a chemo-attractant source.bandingmovie1
