Abstract
An immobilized aminoacylase preparation is obtained by adsorbing tannin on a water-insoluble, hydrophilic carrier to give a water-insoluble tannin preparation, adsorbing aminoacylase on the tannin preparation to give a water-insoluble tannin-aminoacylase preparation, and then binding ferric or ferrous ion thereto. The immobilized preparation obtained above sustains a high rate of enzymatic activity for a long period of time when used in an enzymatic reaction thereof with N-acyl-DL-amino acids.
