Decolorization and biodegradation of reactive sulfonated azo dyes by a newly isolated Brevibacterium sp. strain VN-15
TLDR
Tyrosinase activity was observed during the biotreatment process suggesting the role of this enzyme in the decolorization and degradation process, but no-activity was observed for laccase and peroxidase.
Biodegradation and detoxification of textile azo dyes by bacterial consortium under sequential microaerophilic/aerobic processes
TLDR
As biodegradation under sequential microaerophilic/aerobic process completely detoxified all the selected textile azo dyes, further efforts should be made to implement such methods for large scale dye wastewater treatment technologies.
Decolorization and partial mineralization of a polyazo dye by Bacillus firmus immobilized within tubular polymeric gel
TLDR
Repeated-batch experiments indicate the immobilized cells could decolorize C.I. Direct red 80 and reduce medium COD in five successive batch runs with enhanced activity obtained after each consecutive run, thus suggesting its stability and potential for repeated use in wastewater treatment.
Effectual decolorization and detoxification of triphenylmethane dye malachite green (MG) by Pseudomonas aeruginosa NCIM 2074 and its enzyme system
TLDR
The cytotoxicity and phytotoxicity study revealed the transformation of MG into non-toxic product by P. aeruginosa NCIM 2074, which was benzophenone characterized using GC-mass spectroscopy.
Sequential Microaerophilic-Oxic Phase Mineralization of Azo Dyes by a Monoculture of Pseudomonas Aeruginosa Strain AWF Isolated from Textile Wastewater
TLDR
Data from this study provide evidence of dye mineralization and detoxification by a monoculture of P. aeruginosa in successive microaerophilic/oxic stages.

Decolorization and partial degradation of selected azo dyes by methanogenic sludge
TLDR
Because anaerobic sludge contains sulfate-reducing bacteria and therefore may generate sulfide, azo dyes were tested for chemical decolorization by sulfide to compare rates of chemical and biologic reduction.
Biodegradation of azo dyes in a sequential anaerobic–aerobic system
Abstract A sequential anaerobic–aerobic treatment process based on mixed culture of bacteria isolated from textile dye effluent-contaminated soil was used to degrade sulfonated azo dyes Orange G
Degradation of azo dye Mordant Yellow 10 in a sequential anaerobic and bioaugmented aerobic bioreactor
TLDR
The sequential anaerobic and aerobic bioreactor was able to completely remove the sulfonated azo dye MY10 at a maximum loading rate of 210 mg MY10 (l reactor d) -1 after the appropriate microorganisms for aerobic degradation of SA were bioaugmented into the aerobicBioreactor.
Detoxification and partial mineralization of the azo dye mordant orange 1 in a continuous upflow anaerobic sludge-blanket reactor
TLDR
In batch toxicity assays, azo dye compounds were found to be many times more toxic than their cleavage products towards methanogenic activity in anaerobic granular sludge, confirming the mineralization of 5-aminosalicylic acid to methane.
Biodegradation of 4-aminobenzenesulphonate by a newly isolated bacterial strain PNS-1
A bacterial strain PNS-1, isolated from activated sludge derived from a domestic wastewater treatment unit, could utilize 4-aminobenzenesulphonate (4-ABS) as a sole organic carbon and energy source
The role of (auto)catalysis in the mechanism of an anaerobic azo reduction
TLDR
Experiments indicated that chemical reduction by sulphide is partially responsible for the anaerobic conversions of AO7, and it was made clear that 1-amino-2-naphthol was the dye9s constituent aromatic amines that accelerated the reduction process, possibly by mediating the transfer of reducing equivalents.
Fate and biodegradability of sulfonated aromatic amines
TLDR
The poor biodegradability of sulfonated aromatic amines indicated under the laboratory conditions of this study suggests that these compounds may not be adequately removed during biological wastewater treatment.
Complete biodegradation of the azo dye azodisalicylate under anaerobic conditions.
TLDR
The results suggest that it is possible to design azo dyes that are fully mineralized in the environment; thereby, avoiding ac cumulation of notorious toxic intermediates.
