Abstrakt: The Isoenzymes ofl -Ascorbic Acid Oxidase, isolated and separated according to [1] exhibit a maximum activity withl -Ascorbic Acid in the pH range 5,4–6,0 with temperature optima of 30, 39 and 40°C. Cu2+ inactivates the reaction. In this property the enzyme corresponds to other enzymes of different origin. The activating effect of NaCl with optimum activity near 0,6 mol concentration has not been described previously.
