Biofilms in Ecology and Evolution

Biofilms in Ecology and Evolution

Why do bacteria form biofilms? Bacteria that are bound in biofilms are highly resistant against antibiotics and other chemical insults of the environment, which is a clear evolutionary advantage of forming biofilms. However, we recently found the mechanisms underlying the most important selective advantage of making a biofilm: predation avoidance by bacteriophages. [Vidakovic, et al. 2017

We also recently discovered another reason for why bacteria may want to form biofilms: physical aspects of the biofilm life style strongly favor the evolution of simple social behaviors, such as the production of shared resources or "public goods". [Drescher, et al. 2014Nadell, et al. 2013].
