Abstract
Microorganisms are immobilized by adding microorganism cells to an aqueous solution of a mixture of a polymerizable starch and a polymerizable monomer, and, thereafter, polymerizing the polymerizable starch and polymerizable monomer, to prepare a polymer gel with microorganism cells enclosed therein. The polymerizable starch is prepared by introducing an acrylamidomethyl group into starch. The polymer gel has high mechanical strength and can be used repeatedly over long periods of the time while maintaining at high levels the reactivity of the microorganism enclosed therein.
