PURPOSE:To obtain a stable immobilized mold of bacterium keeping optimum activity simply, by polymerizing aqueous suspension containing a bacterium mold in the presence of a specific resin, a crosslinking agent, a radical polymerization initiator and a pH buffer agent at low temperature. CONSTITUTION:10-30wt% polyethylene glycol monomethacrylate having an average number m of ethylene oxide addition of >=4 as an unsaturated polyester resin, 0.3-1.5wt% N,N'-methylenebisacrylamide as a crosslinking agent, >=0.1wt% K2S2O3 as a radial polymerization initiator and >=0.2wt% dimethylaminopropionitrile as a polymerization promotor are blended with a pH buffer agent and aqueous suspension containing a bacterium mold and polymerization reaction is carried out at pH6-8 at <=40 deg.C. Then, the inclusion gel is immobilized to give an immobilized bacterium mold.
