enzyme immobilized on CNBr-Ag is completely inactive after 16 h incubation at 50°C. Enzymes immobilized on cyanogen bromide or glyoxyl agarose maintain 100% of their initial activity after 16 h at 50°C. Enzyme immobilized on monoaminoethyl-N-aminoethyl-glutaraldehyde or monoaminoethyl-N-aminoethyl-agarose loses more than 50% of its initial activity after 16 h at 50°C
