the polymerization process. During the enzymatic polymerization,
the produced amylose included the PVL graft chains in the
intermolecular guest copolymers. Therefore, the formed inclusion
complexes acted as the cross-linking points for the formation of the
hydrogel. Furthermore, the enzymatic disruption (Fig. 8.10a) and
reproduction of the hydrogels (Fig. 8.10b) were achieved by the
combination of the
-amylase-catalyzed hydrolysis of the amylose
component and the formation of amylose by the phosphorylase-
catalyzed polymerization. Therefore, it should be noted that the
present hydrogel exhibits the enzymatically recyclable behavior by
means of the two enzyme-catalyzed reactions.
