Simple models of microbial dynamics and evolution (part 2)
I will continue my series of talks on microbial evolution. I will finish off the case of a single species in a chemostat and move on to the case of two bacterial species competing for food. I will begin with a simple, Lotka-Volterra type of competition and then I will discuss a more realistic case of two species in the chemostat. I will show how this can be used to experimentally determine fitness advantage - a driving force of biological evolution - of one bacterial species over another one with very high precision. Finally (if time permits) I will consider multiple species.
