比较了木质素过氧化物酶和辣根过氧化物酶对硫酸盐废水的脱色效果。游离木质素过氧化物酶和辣根过氧化物酶从硫酸盐废液中去除颜色。将III型木质素过氧化物酶、冻干真菌培养物和辣根过氧化物酶固定在CNBr-Sepharose 4 B上，48 h内脱色率分别提高了2.9倍、4.5倍和2.6倍。木质素过氧化物酶I型是有效的，只有在固定化形式的脱色。一般来说，固定化形式的所有研究系统表现出的平均值约30%的聚合物消耗和非常少的解聚。木质素过氧化物酶和冻干真菌培养物被证明具有相当大的处理硫酸盐废水的潜力。
Color removal from Kraft effluent by lignin peroxidase and horseradish peroxidase was compared. Free lignin peroxidase and horseradish peroxidase removed color from kraft effluent. Immobilization of lignin peroxidase type III, lyophilized fungal culture and horseradish peroxidase on CNBr-Sepharose 4B improved the decolorization by factor of 2.9, 4.5 and 2.6, respectively in 48 h. Lignin peroxidase type I was effective only in the immobilized form in decolorization. In general, the immobilized form all the studied systems exhibited an average value around of 30% polymer consumption and very little of depolymerization. Lignin peroxidases and lyophilized fungal culture were shown to have considerable potential for treating Kraft effluents.
