Enzymatic hydrolysis of chitosan films in water and physiological solution

详细

It was shown that the processes of enzymatic hydrolysis of chitosan in aqueous acetic acid and on the surface of chitosan films in a solution of hyaluronidase in acetic acid are described by uniform kinetic constants. Kinetic parameters of enzymatic hydrolysis of the chitosan film samples in water and in physiological solution (Ringer–Locke’s solution) were determined. It was found that the introduction of medicinal agents and low-molecular-weight electrolytes to a chitosan-based film material reduces the rate of enzymatic hydrolysis of the films, which may indicate a possible increase in their service life when used on the wound surface.
