The carrier bodies are sheet-like structures with a small thickness in comparison with the carrier body surface. The carrier bodies are kept spaced apart by means of spacing bars (28), defining flow paths (36) between the carrier bodies. In a process for producing porous carrier bodies for microorganisms, plastics particles (70) are introduced into a moulding space (52) and bonded together therein by application of heat. With this process, an endless extrudate (46) of carrier body material may be produced, from which the individual carrier bodies may be cut off. Alternatively, the process may be carried out by means of a series of pairs of mould halves passing through a mould filling station and a heat supply station.
