Two polyamide 6,6 substrates with different constructions, namely a model substrate and a fabric, were hydrolyzed using native cutinase and L182A cutinase mutant (from Fusarium solani pisi) and a protease (subtilisin from Bacillus sp.). The catalytic efficiency of these enzymes, measured in terms of hydrolysis products release, was measured for both substrates and the protease released five times more amines to the bath treatment. The L182A cutinase mutant showed higher activity when compared with the native enzyme.All enzymes have shown activity additive effects with higher levels of mechanical agitation for polyamide fabrics. The results achieved are of paramount importance on the design of a process of enzymatic functionalization of polyamide.
