Small letters on the same column show the difference between the storage periods; uppercased letters in the same row show the difference between enzyme concentrations for each enzyme. The difference between storage periods and enzyme concentrations is at level of 0.01 (𝑃<0.01) and *0.05 (𝑃<0.05) importance.
