Abstract
Immobilized enzyme granules prepared by mixing inert filler particles into an aqueous solution or dispersion of a water soluble binder, followed by granulating the mixture so as to form carrier granules. Enzyme is immobilized on the hydrophilic surfaces of the carrier granules. If not already insoluble in the medium for the intended enzymatic reaction, the binder in the granules is rendered insoluble, e.g., water insoluble. Proteins are preferred binder materials, and glutaraldehyde is the preferred reagent for bonding enzyme to the carrier granules and for water insolubilizing the binder.
