Kinetic study of catalase adsorption on disperse carbonaceous matrices
The effect of the main factors known to govern the kinetic regularities of enzyme adsorption, such as enzyme solution concentration, temperature, pH, specific surface of the adsorbent, etc., were studied. Two kinds of disperse carbonaceous materials-activated carbon NORIT and carbon black PM-100, were used as matrices for enzyme immobilization. For both immobilization matrices studied, the amount of the adsorbed enzyme was found to reach saturation at catalase (CAT) enzyme concentrations exceeding 20 mg·mL−1 (∼100 μM). The pH of the solution affected the adsorption capacities of the selected immobilization matrices; larger amounts of CAT adsorbed were estimated in neutral and alkaline solutions than under acidic conditions for enzyme immobilization. UV-spectrophotometry was employed as a basic analytical approach in this study.
