    摘要: Physically strong particles containing an immobilized enzyme are prepared for use in a fixed bed-column. The particles are prepared by adding a homopolymer of 1-amino ethylene or a copolymer of 1-amino ethylene and N-vinyl formamide to an aqueous medium containing an enzyme, adding a cross-linking agent to cross-link the enzyme and polymer and cause flocculation, and dewatering, sub-dividing and drying the resultant flocculant. Preferably, the enzyme is glucose isomerase and the cross-linking agent is glutaraldehyde, polyazetidine or diisocyanate.
