文摘

A new method for introducing enzymes into cellulosic matrixes which can be formed into membranes,films, or beads has been developed using a cellulose-in-ionic-liquid dissolution and regeneration process.Initial results on the formation of thin cellulose films incorporating dispersed laccase indicate that activeenzyme-encapsulated films can be prepared using this methodology and that precoating the enzyme with asecond, hydrophobic ionic liquid prior to dispersion in the cellulose/ionic liquid solution can provide anincrease in enzyme activity relative to that of untreated films, presumably by providing a stabilizingmicroenvironment for the enzyme.
