title: Immobilization of penicillin G acylase onto ion exchange and hydrophobic resins.
abstract: Penicillin G acylase was immobilized on numerous cation exchange resins and hydrophobic adsorbents. Amberlite XAD-7 was the matrix of choice among the matrices studied for the immobilization of enzyme. Binding of 96.8% and expression of 82.6% of the penicillin G acylase was achieved on XAD-7. Penicillin G acylase immobilised on XAD-7 was used for 80 cycles for the production of 6-PA in a stirred tank reactor.
