"POROUS INORGANIC CARRIERS BEARING A GROWTH OF MICRO-ORGANISMS - PROCEDURE FOR IMMOBILISING MICRO-ORGANISMS AND CARRIER BODIES SUITABLE FOR THIS PURPOSE" ABSTRACT OF THE DISCLOSURE For the immobilisation of micro-organisms and animal cells, in particular for anaerobic processes, such as the purification of waste water or for the biotechnological production of nutrition- essential and pharmocological substances, porous sintered bodies are employed as inorganic carrier bodies. In particular sintered glass in the form of Raschig rings with a double-pore structure, are employed, which are characterized by porosity-determining through-going macropores that permit a free exchange of fluid and gas from the interior of the carrier to the surroundings, and by open microporus within the macropore walls, the diameter of the micropores being of the same order of magnitude as the size of the micro-organisms or cells. These carrier bodies have an open pore volume of 35% to 85%, 20% to 80% being accounted for by the macropores having a diameter of 20 to 500 µm , and 15% - 5% by micropores having a diameter of 1 - 10 µm. These bodies are obtained by sintering a powder mixture comprising fine-grain material and a coarse-grain substance melting at a higher-than-sintering temperature and separable from the sintered product, allowing the latter to cool and separating (dissolving) out the soluble component.
