A carrier for immobilising biologically active materials, such as enzymes and microorganisms. The carrier is characterised in that it consists of a porous body of joined-together particles of a comminuted porous sintered glass fibre matrix. Preferably, the particles are held together at the points of contact with one another by a carbonised organic binder. The particles of sintered glass fibre matrix which, generally, have an average diameter of about 0.005-5 cm, preferably about 0.005-0.05 cm, preferably have a density of 20-2000 kg/cm<3> and have been obtained from fibres having a diameter of 0.3-100 mu m. The carbonised organic binder preferably is selected among polymeric binders, such as polyacrylates, polyvinyl acetates, and polyvinyl acetals. |
