Abstract
An immobilized aminoacylase is prepared by bonding aminoacylase to a water-insoluble porous anion exchanger such as a porous phenolic resin, porous styrene resin, porous silica or porous glass having anion exchange groups and treating the bonded amino-acylase with a crosslinking agent such as an aliphatic dialdehyde. The porous anion exchanger preferably has a pore size of about 150.degree. to 3,000 A.degree., pore volume of about 0.3 to 1.0 m.sup.1 /g, specific surface area of about 10 to 150 m.sup.2 /g and particle size of above 0.1 to 1.2 mm. Preferred anion exchangers are trimethylammonium-introduced styrene resin and trimethylammonium-introduced silica.
