Catalase Immobilization

In order to extend the domain for applications of such enzyme textile membrane to hydrogen peroxide dismutation, immobilization of catalase has been achieved. Catalase is a hydrogen peroxidase oxidoreductase enzyme that catalyzes the dismutation of hydrogen peroxide according to the following reaction scheme:

The catalytic mechanism has been followed during a long working period by hydrogen peroxide measurements (see experimental section). Figure 19 shows the long-term stability of the catalase-modified textile.
