Abstract

The catalytic activity of carrier bound enzymes is maintained and the channelling and compacting of the bound enzyme is substantially reduced by entrapping the carrier bound enzyme in a self-supporting reliculated cellular material.

Claims

2. An article according to claim 1 wherein said carrier is a carbonyl polymer.

3. An article according to claim 1 wherein said carrier is an aldehyde polymer.

4. An article according to claim 1 wherein said carrier is an acrolein polymer.

5. An article according to claim 1 wherein said cellular material is a polyurethane resin foam.

6. An article according to claim 1 wherein said enzyme is glucose isomerase.

7. An article according to claim 1 wherein said cellular material is a polyurethane resin foam and said enzyme is invertase.

8. An article according to claim 1 wherein said enzyme is invertase and said carrier is polyacrolein.

9. An article according to claim 1 wherein said enzyme is invertase, said carrier is polyacrolein and said cellular material is a polyurethane resin foam.

10. An article according to claim 1 wherein a second reticulated cellular material is positioned about the bound enzyme containing cellular material.
