A model system, consisting of a mixed culture of microorganisms, was used to study the performance of a bench‐scale packed bed bubble column (PBC) bioreactor treating trimethylamine. Three mesophilic bacterial strains were selected, mixed and acclimatized to grow with trimethylamine as the sole carbon source; degradation kinetic constants were determined for a bacterial suspension system. Gas transfer to the liquid phase was modelled in order to characterize solute transport and availability into the biofilm. The overall performance of the system is discussed based on mass transfer considerations.
