Abstract
The present invention provides an effective process for an enzymatic reaction which utilizes the enzyme membrane of the invention. The enzyme membrane consists of an enzyme strongly entrapped in a membrane base, said base being porous, fibrous, or roughened material which is permanently self-polarized or maintained polarized under an electric field. This enzyme membrane catalytically reacts with a substrate solution without loss of enzyme. The most preferred material for the membrane substrate is expanded porous polytetrafluoroethylene.
Claims16
A device for performing catalytic enzymatic reactions comprising:
- a. a reaction vessel equipped with a valved inlet port for supplying electrically charged colloidal enzyme solution, a valved inlet port for supplying reactant substrate solution, a valved drain port, and an outlet port for discharge of reacted product;
- and
- b. at least one carrier with enzyme entrapped thereon located inside said reaction vessel;
- and
- c. means for inducing a continuous electrical field across said reaction vessel such that, in operation, colloidal enzyme introduced into said reaction vessel migrates to and is held by said carrier under the potential of said electric field, which enzyme is held fixed by electrical forces during continuous enzymatic reaction of said reactant to reacted product with no substantial loss of enzyme.
