PREPARATION OF IMMOBILIZED ENZYME, IMMOBILIZED MICROORGANISM AND GROUP OF IMMOBILIZED MICROORGANISM

摘要

PURPOSE:To produce an immobilized product resistant to the attack of microorganisms, having high gel strength, and formable to an arbitrary form, at a low cost, by gelatinizing a mixture of an aqueous solution of polyvinyl alcohol and an enzyme or microorganism, etc. in a saturated aqueous solution of boric acid. CONSTITUTION:One or more kinds of enzymes, microorganisms or microbial groups are mixed with an aqueous solution of polyvinyl alcohol, and the mixture is gelatinized in saturated aqueous solution of boric acid to obtain the enzymes, etc. included and immobilized in the monodeol lattice of polyvinyl alcohol-H3 BO3. The polyvinyl alcohol is preferably a partially saponified polyvinyl alcohol having a polymerization degree of 1,000-2,000 and a saponification degree of 87-89%, or a completely saponified polyvinyl alcohol having a saponification degree of =98%.
