1. The process of preparing cellulose fibers of high permeability containing englobed enzymatic material adapted to exert catalytic activity in enzymatic reactions, which consists of the steps of dissolving nitrocellulose in a solvent which is insoluble in water, preparing an aqueous solution of said enzymatic material, emulsifying said solutions, spinning said emulsion into a coagulating bath to produce nitrocellulose fibers containing englobed enzymatic material, and then treating said fibers with a reducing agent under operating conditions which do not damage the enzymatic material so that nitro groups are removed from said nitrocellulose.
