Granular carrier for immobilizing microbial cells and apparatus for producing the granular carrier

摘要

A microorganism cells-immobilizing granular carrier and its manufacturing system.PPSaid microorganism cells- immobilizing granular carrier, which has a specific gravity of 1.00 to 1. 20, and which has a contact angle of 2° to 30° 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.
