Immobilization of trypsin on chitosan gels: Use of different activation protocols and comparison with other supports

Trypsin was immobilized on chitosan gels coagulated with 0.1 or 1 M NaOH and activated with glutaraldehyde or glycidol. The derivatives were characterized by their recovered activity, thermal (40, 55 and 70 °C) and alkaline (pH 11) stabilities, amount of enzyme immobilized on gels for several enzyme...
