METHOD OF IMMOBILIZING LIVE MICROORGANISMS

摘要

A live microorganism is immobilized into a hydrogel by adding the live microorganism-into a 1-25 wt.% aqueous solution of a polyvinyL Alcohol having degree of hydrolysis not less than 95 mo1% and a viscosity-average polymerization degree of not less than 1,500, pouring, the resulting aqueous suspension into a desired shape of a vessel or mold, freeze-molding the aqueous suspension at a temperature lower than -6.degree.C, then vacuumdehydrating the resulting molded article without thawing it to a dehydration percentage not lower than 5 wt.%, and if required immersing the dehydrated article in water.
