Odours containing some hydrophilic and hydrophobic compounds could be efficiently removed by the degradation of bacteria and fungi in an integrated bioreactor. Microorganisms from the integrated bioreactor were observed and identified. The amount, species and distribution characteristics of the microorganisms depended on the properties of the compounds being treated, the concentration and the microenvironment in the integrated bioreactor. Microscopic investigation of microorganism distribution of the packing material showed that much more biomass accumulated on the surface, in which fungi were dominant, compared with only a few bacteria inside the packing material. Symbiotic bacteria could grow on the fungi mycelium.
