ABSTRACT:
Carrageenan-immobilized enzymes are prepared that are stable and retain high activity toward substrates when used in substantially water-immiscible organic solvents. The carrageenan-immobilized enzymes are preferably prepared by introducing droplets of an enzyme/carrageenan solution into a chilled alcohol saturated with a potassium salt and hardening the droplets in the alcohol. The alcohol is selected from n-butanol, benzyl alcohol, crotyl alcohol, n-propanol, isopropanol and sec-butanol. Reactions catalyzed by a .kappa.-carrageenan-immobilized esterase include steroselective transesterifications and hydrolysis reactions.
