Abstract Vertical Rotating Immobilized Cell Reactor was designed and built for glucose conversion into ethanol. Immobilized biomass units with Z.mobilis cells attached into polyurethane foam discs were fixed along a rotating shaft inside the bioreactor. The effect of rotation speed on the concentration of immobilized biomass was studied. Stability of the bioreactor over long-term operation was dependent on the concentration of the immobilized biomass. With fermentation carried out at 6 rpm a constant active immobilized cell concentration of only 34.5 g/l was maintained and used to convert up to 140 g glucose/l into more than 70 g ethanol/l with a volumetric ethanol productivity of 63 g/l/h.
