Abstract
A cross-linked enzyme membrane is prepared by directly adsorbing enzymes into the pores of a microporous non-fibrous filter membrane made of a silica modified vinylchloride polymer and then cross-linking the enzyme with a bi-functional coupling agent whereby enzyme molecules are cross-linked to each other without chemically bonding the enzyme molecules to the membrane. The cross-linked enzyme membrane is used to carry out enzymatic reactions by passing a solution of substrate for the enzyme through the membrane under a pressure differential.
