<p>PURPOSE:To obtain the title carrier retaining a large amount of cells, having excellent degassing and liquid contact efficiency by heating porous ceramic granules to a temperature to soften the surface of thermoplastic polymer granules and fusing the porous ceramic granules to the thermoplastic polymer granules by blending while stirring. CONSTITUTION:Porous ceramic granules having a chemical composition of 59.6% SiO2, 34.8% Al2O3, 2.0% Fe2O3, 2.1% K2O, 0.8% TiO2, etc., and 10-50% based on volume of the porous ceramic granules of thermoplastic polymer granules (e.g. styrene polymer granules) are prepared. The porous ceramics are put in a heat-resistant container, heated to a temperature to soften the surface of the thermoplastic polymer granules in an electric furnace, taken out, the porous ceramic granules 1 are fused to the circumference of the thermoplastic polymer granules 2 by blending while stirring to give the objective microorganism immobilizing carrier retaining a large amount of cells, having excellent degassing and liquid contact efficiency and improved fluidity.</p> |
