A study of gelled enzyme ultrafiltration reactors

Experiments were carried out in UF reactors with dynamically formed gelled enzyme artificial membranes. Unstirred batch systems and UF reactors with continuous recirculation of the substrate on the membrane were investigated. A significant increase in enzyme stability was tested in both systems. The enzymes used were acid phosphatase, urease, and β-glucosidase. The agreement between the experimental results and the predictions of a simple analytical model for the two classes of UF heterogeneous enzymatic reactors is generally satisfactory.
