Decolorization of dyes from textile wastewater by Trametes versicolor.

Treatment of a Textile Effluent from Dyeing with Cochineal Extracts Using Trametes versicolor Fungus

Trametes versicolor (Tv) fungus can degrade synthetic dyes that contain azo groups, anthraquinone, triphenylmethane polymers, and heterocyclic groups. However, no references have been found related to the degradation of natural dyes, such as the carminic acid that is contained in the cochineal extract. Experiments to determine the decolorization of the effluent used in the cotton dyeing process...

Role of Laccase and Low Molecular Weight Metabolites from Trametes versicolor in Dye Decolorization

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...

Trametes hirsuta Dyes with a Laccase from Decolorization and Detoxification of Textile

Valorization and Biodecolorization of Dye Adsorbed on Lignocellulosics Using White Rot Fungi

Biosorption of dyes by lignocelluloses may be an effective method for removing dyes from textile effluents. However, the resulting dyeadsorbed lignocellulosic materials may constitute another pollution problem. An integrated method can solve this problem. Here, various lignocelluloses were tested for their Astrazon Black and Astrazon Blue dyes removal activities. The dye adsorbed after 30 min c...

Decolorization of Ionic Dyes from Synthesized Textile Wastewater by Nanofiltration Using Response Surface Methodology

Decolorization of aqueous solutions containing ionic dyes (Reactive Blue 19 and Acid Black 172) by a TFC commercial polyamide nanofilter (NF) in a spiral wound configuration was studied. The effect of operating parameters including feed concentration (60-180 mg/l), pressure (0.5-1.1 MPa) and pH (6-10) on dye removal efficiency was evaluated. The response surface method (RSM) was utilized for th...
