ABSTRACT:
An immobilized enzyme granular product suitable for use in expanded and fluidized bed operations is formed by gelatine coating a dense particulate material, e.g., a mineral oxide, and hardening the coating with glutaraldehyde, then treating the coated particles with a pasty mixture of an enzyme substance and polyethylene imine, and thereafter treating the mixture with glutaraldehyde, followed by granulating and drying. Sand and titanium dioxide are preferred particulate materials. Lactase, urease, and inulinase are preferred enzymes, preferably in the form of whole or homogenized microbial cells.
