The work is aimed on the look-up of “green” energy sources. Changes in the mechanism and the selectivity of binding components from the enzyme mixture preparation of Natural Black Horseradish immobilized on the kaolin and aerosil are proved by the sum of physical and chemical methods [1]. The differences in the binding mechanisms of metal-containing sites of enzyme molecules based on the implementation of the spatial separation of enzyme fragments containing Fe, Ni, Cu and Zn metal ions are shown. The implementation of this division improves in 4 times the oxidation activity and stability of the immobilized preparation and creates conditions for the formation of regions capable for specific adsorption of charge. The spatially separated binding of enzyme fragments to inorganic carrier exhibits the stabilizing effect on the formation of the areas capable for charging and accumulating red-ox transformations. Electrochemical methods (CVA and EIS) have shown the possibility for the formation of structures responsible for the accumulation of energy like supercapacitor in the immobilized enzyme systems (see Fig. 1). It should be noted that currents, obtained on native enzyme preparation in many times surpass thos e obtained on purified peroxidase enzyme. Thus, the observable synergetic effect appears in the pr eparation comprised of two enzymes and two co-enzymes. |
