The present study was conducted to evaluate the potential applicability of biological trickling filter system for the treatment of simulated textile wastewater containing reactive azo dyes with bacterial consortium under non-sterile conditions. The percentage decolorization for the treatment of wastewater containing structurally different dyes was found to be higher than 95% in all trials. The ...
The residual dyes from different sources (e.g., textile industries, paper and pulp industries, dye and dye intermediates industries, pharmaceutical industries, tannery, and Kraft bleaching industries, etc.) are considered a wide variety of organic pollutants introduced into the natural water resources or wastewater treatment systems. One of the main sources with severe pollution problems worldw...
Azo dyes are widely prevalent environmental contaminants that are recalcitrant to biodegradation processes and have detrimental biological effects. Hence, exploring the novel microbial agents and to develop ecofriendly cost-effective process is pertinent for treatment of textile effluents. A fungal consortium comprising three strains Penicillium oxalicum SAR-3, Aspergillus niger SAR-6 and Asper...
A review of the literature on the mutagenicity of textile dye products is presented in this article. This review discusses genetic hazards associated with the production and use of textile dyes throughout the world. Mutagenicity of azo and non azo dyes has been considered due to extensive recent data on the carcinogenicity and mutagenicity of this group of dyes. In addition, a section on Salmon...
BACKGROUND Fungal manganese peroxidases (MnPs) have great potential as bio-remediating agents and can be used continuously in the immobilized form like many other enzymes. RESULTS In the present study, purified manganese peroxidase (MnP) enzyme isolated from Ganoderma lucidum IBL-05 was immobilized onto polyvinyl alcohol-alginate beads and investigated its potential for the decolorization and...

The textile industry is one of the industries that generate a high volume of waste water. Approximately 10, 000 different dyes and pigments are manufactured worldwide with a total annual market of more than 7×10 metric tones per year (Ahluwalia and Goyal, 2007). In India textile is one of the oldest establishments with nearly 1569 large cotton textiles industries, which gives employment to near...
Coloured wastewaters are a consequence of batch processes in both dye-manufacturing and dye-consuming industries. Dyes are widely used in a number of industries, such as textile and leather dyeing, food, cosmetics, paper printing, gasoline, with the textile in‐ dustry as the largest consumer. Dyeing as a fundamental operation during textile fibre processing causes the production of more or less...
Bacillus subtilis C3, a commercial textile dye-decolorizing and -degrading bacterium, was isolated from the common effluent treatment plant (CEPT) of the Jetpur textile dyeing and printing industrial sector situated in the district of Rajkot, Gujarat, India. Here, we present the annotated 4.18-Mb draft genome sequence of B. subtilis C3, providing information about the metabolic pathways involve...
Textile wastewater is characterized by strong color, saturation of unfixed dyes and their residues, and organic and inorganic chemicals, such as bleaches, detergents, optical brighteners, fixing, sequestering and finishing agents, carriers, surfactants, equalizers, It is characterized by consumption of high amount of water and production of large volumes of wastewater from various processes, su...
