Abstract

To chemically bind either impure or purified enzymes to polyurethane to produce insolubilized bound enzymes which are still enzymically active and which may be more stable than the original enzyme, and which can be reused without appreciable activity loss and whose physical characteristics can be varied depending on the application for which they are intended.
