PRODUCTION OF L-ALANINE USING IMMOBILISED MICROORGANISMS

摘要

of the Invention Disclosed herein is a hydrophilic polyether polyurethane foam wherein at least 50 mole % of the alkylene oxide units in the polyether segments of the polyurethane are ethylene oxide, said foam having an aspartate decarboxylase-producing microorganism immobilized therein. Also disclosed is a method for preparing the foam and utilizing the foam to prepare L-alanine from L-aspartic acid.
