CARRIERS FROM TRIACRYLATE FOR PENICILLIN ACYLASE IMMOBILIZATION

The properties of carriers made of acrylonitrile (AN) or butyl acrylat e (BA) and crosslinked by trimethylolpropane trimethacrylate monomer ( TMPMA) or trimethylolpropane triacrylate monomer (TMPA) are discussed. The extent of aminolysis of triacrylate copolymers depends on the com onomer composition. The carriers crosslinked with TMPMA have greater p orosity and larger mean pore size than carriers that were crosslinked by TMPA. The enzyme activity on carriers that were obtained by ester g roup aminolysis in BA copolymers is higher than on carriers made of AN . It is found that TMPMA/BA carriers are the best for immobilization o f peniccilin acylase. (C) 1996 Elsevier Science Ltd.
