Title: Silica immobilized enzyme catalyzed removal of chlorolignins from eucalyptus kraft effluent

Abstract: Immobilization of lignin peroxidases type I, II, III, lyophilized fungal culture from Chrysonilia sitophila (TFB-27441) and horseradish peroxidase (HRP) on activated silica were carried out. Immobilized HRP gave 37% decolorization, with 60% mineralization. The most efficient lignin peroxidase was Lip type III with 20% mineralization, 65% COD reduction and 12% decolorization. None of the enzymes which were immobilized exhibited loss of activities after being frozen for 2 months or after 5 d contact with a kraft effluent. Silica appeared as an important immobilizing support in the industrial use of oxidoreductases in environmental studies.
