PURPOSE:To raise substrate permeation of immobilized carrier, by blending cells of microorganism with polyvinyl alcohol, further adding calcium silicate powder to the blend to give a mixture, bringing boric acid into contact with the mixture and gelatinizing. CONSTITUTION:Cells of microorganism are blended with powder consisting essentially of an aqueous solution of polyvinyl alcohol (PVA) and calcium silicate, the mixture is brought into contact with an aqueous solution of boric acid and gelatinized to form a microorganism cell immobilized carrier. When the immobilized carrier is enlarged and shown, a great number of holes h are formed in the carrier C and blended with the cells B. PVA preferably has >=95mol.% saponification degree, >=about 1,000 polymerization degree and about 5-30wt.% concentration. The calcium silicate powder has preferably <=about 0.5mm particle diameter. In this method, since a great number of the holes h are formed in the gel, the microorganism cell immobilized carrier having high substrate permeation is obtained.
