Abstract: Endo-$3-glucanase (endo-pl.4-glucano-glucanase EC, isolated from Trichoderma reesei, was immobilized in calcium alginate beads, retaining 75% of its original activity. The polyanionic moiety surrounding the immobilized enzyme displaced the pH-activity profile to alkaline regions with respect to that of the free enzyme. The enzyme was inhibited by carboxymethylcellulose, but this inhibition appeared to be decreased by immobilization. The enzyme immobilized in alginate beads showed a Km value (1.02% w/…
