Based on a continuum approach to the biofilm problem and on mass balance equations, the competition of several microbial species for space and substrates is described. For the case of steady state and of autotrophic and heterotrophic organisms with given biological kinetics and a common nutrient (oxygen), the effect of relative substrate concentrations on biofilm performance and composition is discussed. The approach allows for a detailed analysis and for an adequate reproduction of experimental observations.
