Azo dye decolorization by a halotolerant exoelectrogenic decolorizer isolated from marine sediment
Chemosphere, 2016Based on both capabilities of extracellular electron transfer and high salt tolerance, marine exoelectrogenic bacteria have the potential to serve as halotolerant/halophilic exoelectrogenic decolorizers (HEDs) for textile wastewater treatment. However, research in this area is still rare.

Decolorization of textile dyeing wastewater byPhanerochaete chrysosporium
Folia Microbiologica, 2003The 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 ...

Laccase-catalyzed decolorization of synthetic dyes
Water Research, 1999Commercial dyes are not uniformly susceptible to microbial attack in conventional aerobic treatment because of their unique and stable chemical structures. Three synthetic dyes with typical chromophores (anthraquinone, azo and indigo) were decolorized by a white-rot fungus Trametes versicolor.

Microbial fuel cells for dye decolorization
Environmental Chemistry Letters, 2017Microbial fuel cells are used for energy production, zero carbon dioxide emission and wastewater remediation. Textile industrial effluents contain organic and inorganic compounds that can fuel microbial fuel cells. Here, we review microorganisms that are used as biocatalyst for dye decolorization with energy production.

Bioprocess and Biosystems Engineering
Dyes in wastewater have adverse effects on the environment and human health. Dye-decolorizing peroxidase (DyP) is a promising biocatalyst to dyes degradation, but the decolorization rates varied greatly which influencing factors and mechanisms remain to be fully disclosed.

Decolorization of dye wastewaters by biosorbents: A review
Journal of Environmental Management, 2010Dye wastewater is one of the most difficult to treat. There has been exhaustive research on biosorption of dye wastewater. It is evolving as an attractive option to supplement conventional treatment processes. This paper examines various biosorbents such as fungi, bacteria, algae, chitosan and peat, which are capable of decolorizing dye wastewaters ...

Decolorization of Azo Dyes by Yeasts
2010Azo 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.

Microbial Decolorization of Reactive Dye Solutions
CLEAN – Soil, Air, Water, 2015The most widely used dyes for coloration of cotton textiles are from reactive class. However, the large amount of unfixed dye causes color in the wastewater, which is environmentally unacceptable. Decolorization of various commercially important reactive dyes in aqueous solutions was attempted by microbial treatment using the bacteria Proteus vulgaris ...

Decolorizing dye wastewater with Fenton's reagent
Water Research, 1992Abstract Five types of simulated dye wastewater, separately prepared with disperse, reactive, direct, acid and basic dyes, were decolorized with a hydrogen peroxide-ferrous ion system, known as Fenton's reagent. The results are that the best pH value for decolorization is below 3.5, the average percent removal of chemical oxygen demand (COD) is about

Endophytic Fungi: Role in Dye Decolorization
2019Endophytic fungi inhabit plant tissues, in either a symbiotic or mutualistic relationship, without harming the host plant. They are known for the production of secondary metabolites, which shield the host from invading pathogens. Endophytic fungi produce extracellular enzymes like laccases that have a potential role to play in dye decolorization.
