Abstract

An immobilized glucose isomerase-producing microorganism is reacted with D-glucose to produce D-fructose. Immobilization is carried out by polymerizing at least one acryloyl monomer in an aqueous suspension containing a glucose isomerase-producing microorganism. The acryloyl monomers employed include acryloylamide, N,N'-lower alkylene-bis-acryloylamide, bis(acryloylamidomethyl)ether and N,N'-di-acryloyl-ethyleneurea.
