Anaerobic biodecolorization mechanism of methyl orange by Shewanella oneidensis MR-1

Applied Microbiology and Biotechnology, 2011
In this work, we investigated the anaerobic decolorization of methyl orange (MO), a typical azo dye, by Shewanella oneidensis MR-1, which can use various organic and inorganic substances as its electron acceptor in natural and engineered environments. S.

Biodecolorization and partial mineralization of Reactive Black 5 by a strain of Rhodopseudomonas palustris

Journal of Environmental Sciences, 2008
A strain of photosynthetic bacterium, Rhodopseudomonas palustris W1, isolated from a lab-scale anaerobic moving bed biofilm reactor (MBBR) treating textile effluent was demonstrated to decolorize Reactive Black 5 (RB5) efficiently under anaerobic condition. By a series of batch tests, the suitable conditions for RB5 decolorization were obtained, namely,

Enhanced Biodecolorization of Synthetic Textile Dyes by NTG Mutagenesis

National Academy Science Letters, 2019
Decolorization potential of different dyes, namely Procion Red Yellow, Acid Yellow-9, Direct Orange-102 and Crystal Violet, by two NTG-induced mutants as well as a wild type of Pseudomonas fluorescens was studied. The mutant M1 possessed significantly better potential as compared to the wild type in the case of all the studied dyes.

Biodecolorization of Synthetic Dyeing Wastewater by Immobilized Halotolerant Cells

Key Engineering Materials, 2017
The high concentration of salt in textile dye wastewater is one of the limiting factors for evaluating an effective biodecolorization system. Thirty-nine strains of salt-tolerant bacteria were screened for their ability to decolorize azo dyes (cationic blue 41) in the presence of 10% NaCl (w/v).

Biodecolorization of the Azo Dye Reactive Red 2 by a Halotolerant Enrichment Culture

Water Environment Research, 2007
The decolorization of the azo dye Reactive Red 2 (RR2) under anoxic conditions was investigated using a mesophilic (35°C) halotolerant enrichment culture capable of growth at 100 g/L sodium chloride (NaCl). Batch decolorization assays were conducted with the unacclimated halotolerant culture, and dye decolorization kinetics were determined as a ...

Bioadsorption and enzymatic biodecolorization of effluents from ethanol production plants

Biocatalysis and Agricultural Biotechnology, 2020
Abstract Distillery effluent must be handled in compliance with the demands and obligations of Environmental Quality Standards (EQS). As Iranian bioethanol plants often face the problem of high color content, therefore, an efficient decolorization process is required to determine the quality of effluent so as to meet demanded standards.

Extractive biodecolorization of triphenylmethane dyes in cloud point system by Aeromonas hydrophila DN322p

Applied Microbiology and Biotechnology, 2012
The biological treatment of triphenylmethane dyes is an important issue. Most microbes have limited practical application because they cannot completely detoxicate these dyes. In this study, the extractive biodecolorization of triphenylmethane dyes by Aeromonas hydrophila DN322p was carried out by introducing the cloud point system.

Increasing manganese peroxidase production and biodecolorization of triphenylmethane dyes by novel fungal consortium

Bioresource Technology, 2011
A fungal consortium-SR consisting of Trametes sp. SQ01 and Chaetomium sp. R01 was developed for decolorizing three kinds of triphenylmethane dyes, which were decolorized by individual fungi with low efficiencies. The fungal consortium-SR produced 1.3 U ml(-1) of manganese peroxidase, 5.5 times higher than that produced by the monoculture of Trametes sp.

Biodecolorization and Biodegradation of Sulfur Black by the Strain Aspergillus sp. DS-28

Processes
The textile industry significantly contributes to environmental pollution through its use of synthetic dyes, especially sulfur black, known for its toxicity and resistance to degradation. This research focuses on a fungal strain, Aspergillus sp. strain DS-28, isolated from activated sludge, which exhibits an exceptional ability to biodegrade sulfur ...

The Potential Application of Light-Emitting Diode on Biodecolorization of Azo Dye

Advanced Materials Research, 2013
In the previous study, the decolorization of azo dye was significantly enhanced by the light irradiation. The aim of this study is to investigate the effect of methyl orange decolorization under light-emitting diode (LED). The effect of media, pHs, and nitrogens on methyl orange decolorization by freely suspended cells are examined.
