Anaerobic treatment system was used for determination of colour removal under batch conditions. Azo-dye (Reactive Black 5, RB 5) with glucose as a carbon source was used as a synthetic wastewater. The decolourization process follows first order kinetics with respect to RB 5 azo-dye concentration in batch conditions. Decolourization rate constant (k1) value for dye concentration of 150 mgL was 0...

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 ...

White rot fungus Marasmius sp. BBKAV79 (GenBank accession number-KP455496, KP455497) exhibited decolourization and degradation of Navy blue HER dye (concentration 50 mg l-l) within 24 h under shaking condition. In the present study, various investigated parameters like initial dye concentration, pH, temperature, carbon and nitrogen sources were optimized to develop a faster decolourization proc...

Efficacy of a white rot fungus G. lucidum for reduction of colour of paper mill effluent under various growth conditions was evaluated. G. lucidum cultured in IBME medium supported maximum colour reduction on 18th day of fungal growth. The optimization of growth parameters further improved colour reduction. The 18 day old culture at 4 g/l inoculum concentration resulted in maximum decolourizati...

The aim of the study was to investigate decolourization Methylene Blue (MB) in aqueous solution using advanced oxidation processes (AOPs) and biosorption comparatively. Photocatalytic MB studied TiO2 as catalyst. photocatalytic by direct UV irradiation alone, only TiO2/UV investigated. It found that process increased with decreasing pH, rate also presence when compared alone. Decolourization Fe...

Lignin degrading white rot fungi, Schizophyllum commune and Lenzites eximia were collected from the living tree of Tramarindus indica and burnt tree respectively from the Western Ghats region of Tamil Nadu, India. The fungi were used for the decolourization of azo dyes such as congored, methylorange, erichrome blackT and also for decolourization of the dye industry effluents. Removal of azo dye...

Presence of colour in water will make it unsuitable for human consumption. Textile industries have the major role in imparting colour in natural water bodies as their outlets are opened to them. These industries rely upon azo dyes as it impart brilliant colour to fabrics. But its presence in water bodies creates serious problems. Structure of an azo compound is a very important factor to be con...

Dyes are synthetic organic compounds widely used in various industries such as, textile, leather, plastic, food, pharmaceutical, and paints manufacturing industries. Coloured effluents are highly toxic to the aquatic life and mutagenic to humans. Wastewater containing dyes has become an important issue demanding serious attention. Among the synthetic dyes, azo dyes are the largest and most wide...

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. ...

The application of synthetic dyes in various industries improved the aesthetic properties of the products, but the discharge of dye-containing effluent into water bodies leads to serious environmental problems. Till date, colour removal from effluent is still a challenge due to the absence of economically attractive treatments. In this study, decolourization of a synthetic dye – Remazol brillia...
