ОКИСЛЕНИЕ АРОМАТИЧЕСКИХ АМИНОВ ИММОБИЛИЗОВАННЫМИ ОКСИДОРЕДУКТАЗАМИ

Creation and research of physical and chemical properties and kinetic parameters of effective catalysts of o-dianisidine oxidation on the basis of the Horseradish peroxidase immobilized on various firm carriers was a research objective. As a result of work multilayered heterogeneous catalysts on the basis of the Horseradish peroxidase immobilized on the ion-exchangers KU 2-8 and Sepabeads EC-HA403 were synthesized, the component structure of catalysts is optimized, kinetic parameters of the synthesized catalysts are determined, is revealed that the most effective of the synthesized catalysts is the system " KU 2-8- hitosan-glutaric dialdehyde-peroxidase". Besides, it is revealed that residual activity of the immobilized peroxidase is lower than activity of native enzyme, however catalysts are stable in consecutive experiments, and the immobilization does enzyme more convenient for application in technological processes.
