Abstract

PURPOSE: To prepare an enzyme-containing membrane capable of maintaining high enzymatic activity level even after the use for a long period, by covering an enzyme- containing porous substrate with a dense surface layer having micropores and an inner layer having relatively rough porous structure.
CONSTITUTION: A porous substrate containing enzyme, e.g. sheet, tube, rod, etc. made of non-woven or woven cloth of natural or synthetic fiber, is coated with a polymer solution obtained by dissolving a polymer such as saponified ethylene- vinyl acetate copolymer, cellulose acetate, etc. in a water-miscible organic solvent such as dimethyl sulfoxide, phenols, lower alcohol, etc. The coated substrate is brought into contact with a coagulating liquid composed mainly of water to coagulate the polymer. The enzyme-containing porous substrate can be coated by this process with an anisotropic polymer film composed of a microporous dense surface layer and an inner layer having relatively rough porous structure.
