ABSTRACT:
A porous inorganic oxide carrier body for immobilizing living cells is prepared from inorganic oxide particles such as clay particles. The particles have an average particle size of from 0.01 to 20 microns, and the carrier body has a total pore volume of 0.05 to 1.0 cc/g and an average pore diameter of 50 to 700 .ANG., and has substantially no pore volume in the range of 800 .ANG. or greater. The carrier is prepared by forming a mixture containing the particles, a liquid medium and optional ingredients including zeolite and activated carbon, and forming the mixture into a shaped carrier body which may be optionally dried and calcined. Typical shapes of the carrier include spheres, cylinders, rings, honeycombs and shaped monoliths. Bacteria and other microorganisms immobilized on the carrier are useful for treatment of contaminated waste streams or contaminated vapors, or for other uses for which microorganisms are used such as the synthesis of chemicals.
