本文研究了从处理纺织废水的好氧生物反应器中分离出的混合微生物对联苯胺偶氮染料Direct Black-38的脱色、生物降解和脱毒作用。研究表明，直接黑-38可以生物转化为联苯胺和4-氨基联苯，然后这些有毒中间体完全脱色和生物降解。从细胞毒性研究得出结论，染料的解毒发生在有毒中间体被培养物降解之后。
The present study deals with the decolorisation, biodegradation and detoxification of Direct Black-38, a benzidine based azo dye, by a mixed microbial culture isolated from an aerobic bioreactor treating textile wastewater. The studies revealed a biotransformation of Direct Black-38 into benzidine and 4-aminobiphenyl followed by complete decolorisation and biodegradation of these toxic intermediates. From cytotoxicity studies, it was concluded that detoxification of the dye took place after degradation of the toxic intermediates by the culture.
