CHITIN-GRAFT-POLY(2-METHYL-2-OXAZOLINE) ENHANCED SOLUBILITY AND ACTIVITY OF CATALASE IN ORGANIC-SOLVENT

Catalase from bovine liver was lyophilized from an aqueous solution co ntaining chitin-graft-poly(2-methyl-2-oxazoline) (3), which was synthe sized by the reaction of 52% deacetylated chitin (1) with living poly( 2-methyl-2-oxazoline) (2). The rate of consumption of H2O2 in chlorofo rm catalyzed by the lyophilized catalase with 3 was enhanced more than 10 times that by catalase without 3. The dispersibility and solubilit y of lyophilized catalase with 3 in chloroform were improved in compar ison with catalase itself. (C) 1998 Elsevier Science B.V. All rights r eserved.
