Recently, the enzymatic approach has attracted much interest in the decolorization/degradation of textile and other industrially important dyes from wastewater as an alternative strategy to conventional chemical, physical and biological treatments, which pose serious limitations. Enzymatic treatment is very useful due to the action of enzymes on pollutants even when they are present in very dilute solutions and recalcitrant to the action of various microbes participating in the degradation of dyes. The potential of the enzymes (peroxidases, manganese peroxidases, lignin peroxidases, laccases, microperoxidase-11, polyphenol oxidases, and azoreductases) has been exploited in the decolorization and degradation of dyes. Some of the recalcitrant dyes were not degraded/decolorized in the presence of such enzymes. The addition of certain redox mediators enhanced the range of substrates and efficiency of degradation of the recalcitrant compounds. Several redox mediators have been reported in the literature, but very few of them are frequently used (e.g., 1-hydroxybenzotriazole, veratryl alcohol, violuric acid, 2-methoxy-phenothiazone). Soluble enzymes cannot be exploited at the large scale due to limitations such as stability and reusability. Therefore, the use of immobilized enzymes has significant advantages over soluble enzymes. In the near future, technology based on the enzymatic treatment of dyes present in the industrial effluents/wastewater will play a vital role. Treatment of wastewater on a large scale will also be possible by using reactors containing immobilized enzymes.

氧化还原酶在纺织品和其他合成染料从污水中脱色和脱毒中的潜在应用：综述。

近年来，酶法已引起人们对废水中纺织品和其他工业上重要染料的脱色/降解的关注，这是对传统化学，物理和生物处理方法的一种替代策略，这构成了严重的局限性。由于酶对污染物的作用，即使它们存在于非常稀的溶液中，并且对参与染料降解的各种微生物的作用都具有顽固性，酶处理还是非常有用的。已在染料的脱色和降解中利用了酶的潜力（过氧化物酶，锰过氧化物酶，木质素过氧化物酶，漆酶，微过氧化物酶-11，多酚氧化酶和偶氮还原酶）。在这些酶的存在下，一些顽固的染料没有被降解/脱色。某些氧化还原介体的加入增加了底物的范围和难降解化合物的降解效率。文献中已经报道了几种氧化还原介体，但是很少使用它们（例如1-羟基苯并三唑，藜芦醇，紫尿酸，2-甲氧基菲硫oth）。由于诸如稳定性和可重复使用性的局限性，不能大规模地利用可溶性酶。因此，使用固定化酶比可溶性酶具有明显的优势。在不久的将来，基于酶处理工业废水/废水中存在的染料的技术将发挥至关重要的作用。通过使用包含固定化酶的反应器，也可以大规模处理废水。
