Decolorization of a variety of dyes by Aspergillus flavus A5p1

Bioprocess and Biosystems Engineering, 2018
Aspergillus flavus: fungal strain A5p1 is reported here to decolorize a variety of dyes under broad environmental conditions. For the 15 dyes tested, the decolorization efficiencies ranged from 61.7 to 100.0% at an initial concentration of 100 mg/L. Direct Blue 71 (DB71), Direct Blue 86 (DB86), and Reactive Blue 19 (RB19) were selected as models for ...

Decolorization and Degradation of Textile Dyes with Biosulfidogenic Hydrogenases

Biotechnology Progress, 2007
Successful decolorization of azo dyes (Orange II, Amido Black 10, Reactive Black 5, and Reactive Red 120) and industrial textile dye influents and effluents with sulfate-reducing bacteria from within a biosulfidogenic reactor was achieved with decolorizations ranging from 96% to 49% over 144 h.

Decolorization of Azo Dyes by Yeasts

2010
Azo dyes are synthetically produced organic molecules and represent the largest group of commercial dyes. Industrial use for coloring purposes generates huge volumes of dyed effluents, which are of environmental concern. Color removal has been achieved by using microorganisms such as filamentous fungi, especially white rot fungi, and bacterial species.

Decolorization and Degradation of Dyes with Mediated Fenton Reaction

Water Environment Research, 2004
A mediated Fenton system has been evaluated for decolorization of several types of dyes. The result shows that the Fenton system with a dihydroxybenzoic acid (DHBA) chelator‐mediator effectively reduced the color of a diluted solution of Carta Yellow RW liquid, Carta Yellow G liquid, and Cartasol Red 2GF liquid dye to a colorless level after 90 minutes

Decolorization of textile dyeing wastewater byPhanerochaete chrysosporium

Folia Microbiologica, 2003
The potential use of fungal pellets for decolorization of the textile dyeing wastewater was evaluated. The live pellets of the fungus Phanerochaete chrysosporium were found to remove more than 95% of the color of this wastewater within 1 d. The dye-removal capacity was a function of time and was proportional to the agitation rate; the optimum ...

Decolorization of textile dyes by Alishewanella sp. KMK6

Applied Microbiology and Biotechnology, 2011
Alishewanella sp. strain KMK6 was isolated from textile dye-contaminated soil. The strain was able to decolorize and degrade different azo dyes and displayed high dye degradation ability and tolerance. The bacterium could completely degrade 2.5 g l(-1) dye, Reactive Blue 59 within 6 h.

Decolorization of anthraquinone dye by Shewanella decolorationis S12

Applied Microbiology and Biotechnology, 2006
A new species of genus Shewanella, Shewanella decolorationis S12, from activated sludge of a textile-printing wastewater treatment plant, can decolorize Reactive Brilliant Blue K-GR, one kind of anthraquinone dye, with flocculation first. Although S.

Copper–ligand complex for the decolorization of synthetic dyes

Chemosphere, 2004
The reaction system containing Cu(II), hydrogen peroxide and D-arabinono-1,4-lactone was found to be effective in the decolorization and reduction of toxicity of azo, thiazine-, triphenylmethane- and anthraquinone-based synthetic dyes. More than 85% decolorization was obtained with 100ppm Acridine Orange, Azure B, Chicago Sky Blue 6B, Crystal Violet ...

Decolorization of textile indigo dye by ligninolytic fungi

Journal of Biotechnology, 2001
The indigo dye is extensively used by textile industries and is considered a recalcitrant substance, which causes environmental concern. Chemical products used on textile processing, which affect the environment through effluents, can be voluminous, colored and varied.

Decolorization of dyes and textile wastewater by potassium permanganate

Chemosphere, 2005
Decolorization of 10 types of dye solutions by potassium permanganate was studied. Effects of reaction conditions on the decolorization efficiency were examined in batch experiments. The pH value had a significant effect on the decolorization efficiency. When pH value 4.0, the dye solutions were almost not decolorized.
