ABSTRACT:
A granular fixed molded article of an enzyme or microorganism strain is prepared by adding dropwise a liquid composition, composed of (a) a hydrophilic photocurable resin having at least two ethylenically unsaturated bonds per molecule, (b) a photopolymerization initiator, (c) a water-soluble high-molecular-weight polysaccharide having the ability to become a gel upon contact with at least one polyvalent metal ion and (d) an enzyme or microorganism strain, to an aqueous medium containing a polyvalent metal ion to gel the composition in a granular form, and then irradiating actinic light on the resulting granular gel to cure the photocurable resin in the granular gel.
