ABSTRACT:
Insolubilized but active enzymes are prepared by mixing an aqueous solution of the enzyme with a modified phenolic polymer. The phenolic polymer is modified by introducing into the polymer chain either aldehyde groups or diazonium salt groups. The so-produced enzyme products retain a substantial part of the original enzyme activity.
