Dictyostelium discoideum was immobilized by cultivation on inorganic porous matrices consisting of broken pumice or a ceramic catalyst carrier (CeramTec) to produce human soluble Fas ligand (hFasL). These supports were actively colonized by D. discoideum reaching cell (number) densities 10-20 times higher locally than those observed in suspension culture under similar conditions. In repeated batch or continuous operation, hFasL productivities of up to 15-25 μg h −1 l −1 pore volume were attained. The immobilized cell densities and hFasL productivities could be kept constant for a long period of time by repeated renewal or continuous feeding of complex or synthetic medium.

A biofilm model with substrate inhibition is proposed for the activated sludge growing discs of rotating biological contactor (RBC); this model is different from the steady-state biofilm model based on the Monod assumption. Both deep and shallow types of biofilms are examined and discussed. The biofilm models based on both Monod and substrate inhibition (Haldane) assumptions are compared. In addition, the relationships between substrate utilization rate, biofilm thickness, and liquid phase substrate concentration are discussed. The influence order of the factors that affect the biofilm thickness is studied and discussed by combining the Taguchi method and grey relational analysis. In this work, a Taguchi orthogonal table is used to construct the series that is needed for grey relational analysis to determine the influence priority of the four parameters S(B), kX(f), K(s), and K(i).
