The studies regarding decolorization of dyes by laccase may not only inform about the possible application of this enzyme for environmental purposes, but also may provide important information about its reaction mechanism and the influence of several factors that could be involved. In this paper, decolorization of crystal violet and phenol red was carried out with different fractions of extrace...

Decolorization of azo dye Red 3BN by two bacterial species Bacillus cereus and B. megaterium has been analyzed using mineral effluent, consisting of known concentration of the dye in ZZ medium. Physico chemical parameters like carbon source, nitrogen source, temperature, pH and inoculum volume are optimized for the decolorization process by changing one parameter at a time. Optimal condition fo...

The problem of environmental pollution becomes more worrisome day by day, primarily due to the large amounts of wastewater contaminated with various harmful organic compounds, discharged untreated or partially clean into the environment. Feasibility of use of horseradish peroxidase (Amoracia rusticana) in the synthetic dyes decolorization was approved by many researchers. Among a number of supp...

A bacterial strain SVM1 with remarkable ability to decolorization textile dye Reactive Red ME4BL was isolated from the activated sludge soil collected from a common effluent treatment plant (CETP) in Perunduari, Erode district Tamil Nadu. Different parameters such as temperature and pH were optimized for decolorization of Red ME4BL by using isolated bacteria. The most promising bacterial isolat...

Different technologies may be used for decolorization of wastewater containing dyes. Among them, biological processes are the most promising because they seem to be environmentally safe. The aim of this study was to determine the efficiency of decolorization of two dyes belonging to different classes (azo and triphenylmethane dyes) by immobilized biomass of strains of fungi (Pleurotus ostreatus...

Studies were carried out on the decolorization of textile azo dyes by newly isolated halophilic and halotolerant bacteria. Among the 27 strains of halophilic and halotolerant bacteria isolated from effluents of textile industries, three showed remarkable ability in decolorizing the widely utilized azo dyes. Phenotypic characterization and phylogenetic analysis based on 16S rDNA sequence compari...

A potential bacterial strain GSM2, capable of degrading an azo dye Reactive Violet 5 as a sole source of carbon, was isolated from textile mill effluent from Solapur, India. The 16S rDNA sequence and phenotypic characteristics indicated an isolated organism as Paracoccus sp. GSM2. This strain exhibited complete decolorization of Reactive Violet 5 (100 mg/L) within 16 h, while maximally it could...

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...

Dyes are one of the most widely used chemical substances in day-to-day life, including different industries. Dye manufacturers, as well users, experiencing great difficulty complying with stringent regulations on wastewater containing dyes and derivatives. Most industries still use age-old technology machinery thus find it difficult to cope change scenario current environmental disposable limit...
