[Papain immobilization on a fibrous polymer of polyvinyl alcohol]

The paper discusses papain immobilization on modified polyvinyl alcohol fibers by the ion fixation technique. The effect of the chemical structure of polyvinyl alcohol fibers on the basic properties of the bound enzyme has been examined. The level of activity and tolerance to pH changes of the resultant immobilized enzymes have been shown to depend on the papain arrangement in the polymer molecule.
