Abstract
A water-soluble non-colloidal penicillinacylase preparation containing penicillinacylase covalently bound to a water-soluble carrier is produced by reacting penicillinacylase with an activated derivative of a water soluble polysaccharide in aqueous solution. The water-soluble penicillinacylase preparation efficiently hydrolyzes penicillin and permits recovery of 6-aminopenicillanic acid efficiently in extremely high purity.
