Dyes are the most important group of synthetic colorants. They are generally considered as xenobiotic compounds which are very recalcitrant to biodegradation. Some dyes and some of their N-substituted aromatic bio-transformation products are toxic and/or carcinogenic and therefore these dyes are considered to be environmental pollutants and health hazards. In comparison with chemical treatment of dye containing tannery effluent, biological treatment is considered to be the most economical and efficient. In this work, attempts were made to degrade these dyes aerobically and anaerobically. The...
