Latest Patents

Junko Harada holds a patent for "Lipase immobilized on a chitosan carrier." This invention involves producing an enzyme immobilizing carrier by dissolving low-molecular weight chitosan in an aqueous acid solution. The solution is then dropped into a basic solution to create regenerated porous chitosan particles. The process includes reacting these particles with glycidyl ether of an aliphatic polyalcohol and further reacting the resulting chitosan with acid halide or acid anhydride of a higher fatty acid in a polar organic solvent. The enzyme, specifically lipase, is covalently immobilized on the carrier using a polyfunctional cross-linking agent.
