Document Type and Number:
Japanese Patent JP3242927
Kind Code:
B2
Abstract:
A microorganism cells-immobilizing granular carrier and its manufacturing system. Said microorganism cells-immobilizing granular carrier, which has a specific gravity of 1.00 to 1.20, and which has a contact angle of 2 DEG to 30 DEG formed between the carrier surface and n-paraffin, and which has a surface suitable for the attachment of a microorganism, is obtained by dripping a liquid composition containing a hydrophilic photo-curable resin having (a) at least two ethylenically-unsaturated bonds in one molecule, (b) photopolymerization initiator, and (c) water-soluble macromolecular polysaccharide capable of gelatinizing through contact with alkaline metal ions or polyvalent metal ions, into an aqueous medium containing alkaline metal ions or polyvalent metal ions to gelatinize the composition; and irradiating the composition with ultraviolet radiation so as to harden said composition.
