The membrane fraction of Gluconobacter oxydans IFO 3244, involving membrane-bound quinoprotein quinate dehydrogenase and 3-dehydroquinate dehydratase, was immobilized into Ca-alginate beads. The Ca-alginate-immobilized bacterial membrane catalyzed a sequential reaction of quinate oxidation to 3-dehydroquinate and its spontaneous conversion to 3-dehydroshikimate
