Biomass and population size during one week. A) Biomass dynamics as optical density (OD), and B) population size as colony forming units (CFUml-1) during one week’s growth, when Serratia marcescens and Novosphingobium capsulatum where grown either separately or together in batch cultures. For the two-species community, the biomass is combined for both species.
