磺化偶氮染料活性橙16是活性染料中常用的代表，但一些常规处理方法难以降解。为了开发更有效和更具成本效益的处理方法来降解这种顽固染料，白腐真菌灵芝的能力。本研究对我们实验室分离出的用于活性橙 16 脱色和解毒的 En3 进行了研究。灵芝属En3对高浓度活性橙16和浸没培养中含有活性橙16的模拟纺织废水具有很强的脱色能力。该真菌对活性橙16及其模拟染料废水的脱色导致植物毒性降低。灵芝属En3对高浓度活性橙16具有很强的适应性和耐受性。与之前的一些研究相比，灵芝属物种。 En3对Reactive Orange 16的脱色速度和程度均优于之前报道的一些真菌菌株。我们还发现，灵芝菌可以有效地对真实的纺织废水进行脱色。沉水培养中的 En3。灵芝菌生产的粗酶。 En3还可以在体外条件下有效地对活性橙16和模拟纺织废水进行脱色。 (C) 2013 Elsevier B.V. 保留所有权利。
The sulfonated azo dye Reactive Orange 16 is the commonly used representative of reactive dyes, but is hard to be degraded by some conventional treatment methods. In order to develop more efficient and more cost-effective treatment methods for degrading this recalcitrant dye, the capability of the white-rot fungus Ganoderma sp. En3 isolated by our laboratory to decolorize and detoxify Reactive Orange 16 was investigated in this study. Ganoderma sp. En3 had a strong ability to decolorize high concentrations of Reactive Orange 16 and simulated textile wastewater containing Reactive Orange 16 in submerged cultures. Decolorization of Reactive Orange 16 and its simulated dye effluents by this fungus resulted in the decrease of phytotoxicity. Ganoderma sp. En3 had strong adaptability and tolerance to high concentrations of Reactive Orange 16. Compared with some previous research, Ganoderma sp. En3 was superior to some other fungal strains reported previously in the rate and extent of decolorizing Reactive Orange 16. It was also found that the real textile wastewater could be efficiently decolorized by Ganoderma sp. En3 in submerged cultures. The crude enzyme produced by Ganoderma sp. En3 could also efficiently decolorize Reactive Orange 16 and simulated textile wastewater under in vitro conditions. (C) 2013 Elsevier B.V. All rights reserved.
