Abstract
Enzymes are adsorbed on an adsorbent powder in an aqueous medium and a water-miscible monomer is added thereto, and said monomer is polymerized to form a porous gel lump through which a substrate solution can freely pass. The thus formed enzyme composition has long-lasting activity and thus the enzymes can be easily separated from the reaction system and can be used repeatedly.
