    Abstract: Microorganisms or animal cells are cultured in a fluidized or fixed bed bioreactor on porous inorganic sintered support spheres containing inwardly continuous and outwardly open pores. The spheres have a density and diameter such that shear forces created under fluidized bed conditions shear off microorganisms or animal cells grown out of the pores and on the surface of the spheres. Culturing may be carried out in a fixed bed continuous reactor and the bed subjected to intermittent fluidized bed conditions to shear microorganisms or animal cells off the sphere surfaces. The spheres may be coated with a thin plastic layer to increase resistance to abrasion. Also, the spheres may be provided with a surface layer of inorganic and/or organic material for improving immobilization of microorganisms or animal cells. The spheres can be used in degradation of municipal sewage and industrial wastes and for bioengineering production of nutritionally essential and pharmacological substances and other fermentation products.

    Abstract: A process for manufacturing open porous sintered bodies with large open pore volume and defined pore diameters and which at least predominantly consist of glass-ceramics. They are obtained by sintering a mixture of sinterable powder and an inorganic soluble salt with defined grade of grain, the melting point of which is above the densification temperature of the sinterable powder. For the formation of a molded body the mixture of sinterable powder and inorganic salt is submitted to a molding process. The molded body is sintered in a sintering process and the soluble salt being contained in the molded body is lixiviated. As a main constituent the sinterable powder contains a pulverized crystallizable glass powder. The sintering process is performed in such a way that the crystal phases being produced during the crystallization of the crystallizable glass, and therefore the material properties, too, are controlled by the guidance of the sintering process as well as by the ion exchange taking place between the sinterable powder and the inorganic salt and which is controlled by their composition. Afterwards, the sintered body is transformed to the final glass-ceramic texture.
