The enzyme peroxidase is known for its capacity to remove phenolic compounds and aromatic amines from aqueous solutions and also to decolorize textile effluents. This study evaluates the potential of the enzyme horseradish peroxidase (HRP) in the decolorization of textile dyes and effluents. Some factors such as pH and the amount of H(2)O(2) and the enzyme were evaluated in order to determine the optimum conditions for the enzyme performance. For the dyes tested, the results indicated that the decolorization of the dye Remazol Turquoise Blue G 133% was approximately 59%, and 94% for the Lanaset Blue 2R; for the textile effluent, the decolorization was 52%. The tests for toxicity towards Daphnia magna showed that there was a reduction in toxicity after the enzymatic treatment. However, the toxicity of the textile effluent showed no change towards Artemia salina after the enzyme treatment. This study verifies the viability of the use of the enzyme horseradish peroxidase in the biodegradation of textile dyes.
过氧化物酶因其能够从水溶液中去除酚类化合物和芳香胺以及使纺织废水脱色而闻名。本研究评估了辣根过氧化物酶（HRP）对纺织染料和废水进行脱色的潜力。对pH值、过氧化氢和酶的用量等一些因素进行了评估，以确定酶发挥最佳性能的最佳条件。对于所测试的染料，结果表明，活性艳蓝G133%染料的脱色率约为59%，兰纳素蓝2R的脱色率为94%；对于纺织废水，脱色率为52%。对大型溞的毒性测试表明，酶处理后毒性有所降低。然而，酶处理后纺织废水对卤虫的毒性没有变化。本研究验证了使用辣根过氧化物酶对纺织染料进行生物降解的可行性。
