Abstract

ABSTRACT The immobilization of enzymes is one of the key issues in both the field of enzymatic research and industrialization. In this article, we report a facile method for immobilizing Candida antarctica lipase B in an alginate carrier. In the presence of calcium cations, an enzyme–alginate suspension was crosslinked to form beads with a porous structure at room temperature, and the enzymes were well dispersed in the beads. The chiral resolution of α‐phenyl ethanol in the organic phase was tested by the enzyme–alginate beads. The effects of the reaction parameters, such as the enzyme concentration, temperature, and molar ratio of the substrate to the solvent, on the resolution behavior are discussed. Reuse cycle experiments for the chiral resolution of α‐phenyl ethanol demonstrated that the activity of the enzyme–alginate beads was maintained without marked deactivation up to five repeated cycles. © 2013 Wiley Periodicals, Inc.
