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.
本研究涉及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培养物对直接黑 - 38（一种基于联苯胺的偶氮染料）的脱色、生物降解和解毒作用。研究表明，直接黑 - 38 生物转化为联苯胺和 4 - 氨基联苯，随后这些有毒中间体被完全脱色和生物降解。从细胞毒性研究得出结论，该培养物在降解有毒中间体后实现了染料的解毒。
