ABSTRACT:
Biocatalyst such as enzymes or cells are immobilized in hollow porous microspheres for use as bioreactors in biochemical processes. The microspheres are of substantially uniform diameter of 200 to 10,000 microns and of substantially uniform wall thickness of 1 to 1000 microns. Walls of the microspheres are formed of sintered together particles such as inorganic particles. The walls have interconnecting voids that are continuous and extend from outer wall surface to the inner wall surface. The biocatalyst is introduced into the microspheres through macropores in the walls, and then immobilized. Immobilization may be performed by introducing a gel forming material with the biocatalyst and forming a semipermeable gel in situ within the microspheres.
