I thought of something some of my friends studied as a project a year
ago or something. As I understand it bacterial behaviour is functional:
If a is the case then do this; If b is the case then do that. I seem to
remember that the coli-bacteria has three conditions, that affect its
behaviour : heat, butyric acid and mating cycles. I think the behaviour
is something like (please don't hang me up on this - I am not a
biologist and this is second to hand information):

a) if it's warm then move around.
b) if there's butyric acid then eat; override rule a).
c) Unless in a mating cycle; override rules a) and b)

Just thought I'd share it.
