Biodegradation of textile azo-dyes byPhanerochaete chrysosporium.
Of 18 commercially used textile dyes, eight were degraded by the white rot fungus,Phanerochaete chrysosporium, by 40 to 73% based on decrease of colour. Both the lignin-degrading enzyme system ofP. chrysosporium and adsorption to its cell mass were involved in the degradation of the diazo dye, Reactofix Gold Yellow. Degradation was best achieved by adding the dye to the medium and then inoculat...
متن کاملBiodegradation of azo and heterocyclic dyes by Phanerochaete chrysosporium.
Biodegradation of Orange II, Tropaeolin O, Congo Red, and Azure B in cultures of the white rot fungus, Phanerochaete chrysosporium, was demonstrated by decolarization of the culture medium, the extent of which was determined by monitoring the decrease in absorbance at or near the wavelength maximum for each dye. Metabolite formation was also monitored. Decolorization of these dyes was most exte...
متن کاملDecolourization 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. ...
متن کاملBiodegradation of bioaccessible textile azo dyes by Phanerochaete chrysosporium.
Azo dyes are important chemical pollutants of industrial origin. Textile azo dyes with bioaccessible groups for lignin degrading fungi, such as 2-methoxyphenol (guaiacol) and 2,6-dimethoxyphenol (syringol), were synthesised using different aminobenzoic and aminosulphonic acids as diazo components. The inocula of the best biodegradation assays were obtained from a pre-growth medium (PAM), contai...
متن کاملAerobic Biodegradation Characteristic of Different Water-Soluble Azo Dyes
This study investigated the biodegradation performance and characteristics of Sudan I and Acid Orange 7 (AO7) to improve the biological dye removal efficiency in wastewater and optimize the treatment process. The dyes with different water-solubility and similar molecular structure were biologically treated under aerobic condition in parallel continuous-flow mixed stirred reactors. The biophase ...
