Bacterial decolourization of azo dyes

Decolourization and Biodegradation of Reactive Azo Dyes by Mixed Culture

Synthetic dyes, azo dye in particular, are widely found in the effluents from textile industries. The persistence and toxicity of these compounds cause adverse impact in the receiving streams. A mixture of isolated cultures, from domestic sewage treatment plant was found to decolourize reactive azo dyes, Red RB, Blue M2B and Yellow, efficiently in the absence of added external nitrogen source. ...

Decolourization of azo dyes in textile wastewater by microbial processes

Decolourization of Azo Dyes and Dye Industry Effluents by Lignin Degrading Fungus Trametes versicolor

Lignin degrading white rot fungus, Trametes versicolor isolated from the logs of Acacia nilotica L.Del.sp. indica in the Western Ghats region of Tamil Nadu, India. The fungus was used for the decolourization of azo dyes such as orange G, congo red and amido Black 10 B and also for colour removal from the dye industry effluents. Batch studies were conducted in a defined medium with pH-4.5. The r...

Kinetic of Azo Dyes Decolourization by Enterobacteriaceae Species in the Intact Cell Assay System

The method “Intact cell assay” was adopted to assess the influencing factors on the process of decolourization ability of the enterobacteriaceaea specie isolates under predisposed environment. Taken into account several ingredient are added individually as well in combinations in the assay reaction. Values of dye decolourized in μg ml with Multi vitanmins solution (MVS) with glucose 42.53; MVS ...

Decolourization of azo dyes by a newly isolated Klebsiella sp. strain Y3, and effects of various factors on biodegradation

In this study, we isolated and characterized a new strain of Klebsiella sp. Y3, which was capable of decolourizing azo dyes under anaerobic conditions. The effects of physico-chemical parameters on the Methyl Red degradation by the strain were determined. The results indicated that strain Y3 exhibited a good decolourization ability in the range of pH from 4 to 9, temperature from 30 °C to 42 °C...
