(57) [Abstract] [Purpose] As a granular hydrogel carrier composed of a high-molecular polymer obtained by wet coagulation for immobilizing a biocatalyst for a bioreactor, further increasing the adhesion of microorganisms and its adhesion stability. To obtain a granular hydrous gel carrier which can further enhance the [Structure] A granular hydrogel comprising a high-molecular polymer obtained by wet coagulation, characterized in that the surface of its surface skin-like coating is roughened. The surface skin-like coating has a large number of scratches exceeding the film thickness of the coating, or the surface skin-like coating is peeled off at least partially, and the internal sponge layer below the skin-like coating is Those exposed on the surface are more preferable. The manufacturing method is a method in which a granular hydrous gel made of a high-molecular polymer obtained by wet coagulation is mixed with an abrasive by dry or wet stirring. |
