Abstract
Carrier material for the immobilization of microorganisms, particularly for use in connection with microbiological conversion and/or separation of constituents from gaseous or liquid media, is disclosed. The carrier material comprises a dimensionally stable macroporous skeleton comprised of relatively coarse-grain granular material such as sinterable thermoplastic granules, and relatively fine grain microporous material, such as activated charcoal, which are bonded together. The carrier material thus comprises both macropores having a pore size of from about 10 to 200 .mu.m and micropores having a pore size of up to about 0.1 .mu.m depending upon the identity of the five grain microporous material that is used. Additional finely divided materials, such as catalytic agents or density modifying agents, may also be disposed within the macroporous skeleton. The preparation and use of the carrier material is also disclosed.
