Inactivation of Immobilized Fungal Catalase by Hydrogen Peroxide,

摘要

The deactivation of immobilized fungal catalase derived from Aspergillus by peroxide was studied in a continuous,tubular packed bed reactor. Effects of temperature peroxide concentration,and residence time were observed. Comparison with immobilized beef liver catalase showed that fungal catalase is more stable toward peroxide attack. The model of Altomare,et al,which described beef liver deactivation was applied successfully to fungal catalase deactivation. Moreover certain theoretical predictions of the model concerning the effect of space velocity were experimentally confirmed.
