Decolourisation and Detoxification of Reactive Azo Dyes by Saccharothrix Aerocolonigenes TE5

摘要

Reactive azo dyes primarily present in the effluent of textile industries are recalcitrant molecules and are highly toxic enough to impart severe adverse effects on vital organs of human or animal system and are difficult to degrade by biological means. The present study is structured to study the decolourization and detoxification potential of Saccharothrix aerocolonigenes strain TE5 isolated from the soil contaminated with textile effluents. The percent of decolourization was calculated under static and shaking conditions by employing UV-VIS Spectroscopy. The effect of pH, temperature, carbon and nitrogen sources on the rate of decolourization was determined. The toxicity of the degraded products was assessed by germination assay.
