Summary: The research found that biogenic sulfide achieved decolorization of azo dye by directly cleaving azo bonds, with the decolorization efficiency increased up to 3-fold by adding an external carbon source or elevating the initial azo dye concentration. Biogenic sulfide plays a vital role in azo dye decolorization, offering a new possibility for treating dye-laden wastewater.

Summary: Azo dye pollution is a global issue with current treatment methods falling short of emission standards. Microbial electrochemical systems show promise for decolorization, with electrode modification offering a method to enhance performance. Modification with polyaniline and graphene led to the highest decolorization efficiency, attributed to altered metabolic pathways facilitating extracellular electron transfer.

Summary: This study investigated the biodegradation of the azo dye AB113 and identified the key pathways and enzymes involved in its degradation. The results showed that the benzoate and naphthalene degradation pathways played a crucial role in AB113 degradation, and enzymes such as NADH quinone oxidoreductase, N-acetyltransferase, aromatic ring-hydroxylating dioxygenase, and CYP450 were found to be important for AB113 degradation.

Summary: A halo-thermophilic bacterial consortium capable of decolorizing azo dye under high salinity and temperature conditions was enriched in this study, with Bacillus identified as the dominant genus playing a key role in the decolorization process. The consortium demonstrated effectiveness in decolorization of metanil yellow G across a wide range of pH values, temperatures, dye concentrations, and salinities. Additionally, various enzymes such as laccase, manganese peroxidase, lignin peroxidase, and azoreductase were found to be involved in the decolorization process, with a proposed pathway for decolorization based on GC-MS and FTIR results.

Summary: Salinity has adverse effects on the performance of anaerobic MBR in treating azo dye wastewater, resulting in decreased decolorization efficiency and COD removal efficiency. It also leads to increased production of SMP and EPS, which contributes to membrane fouling. The lack of halophilic bacteria is the main reason for the decreased decolorization efficiency in saline environments.

Summary: Mycoremediation of textile effluents, such as synthetic dyes, is an effective and eco-friendly method. Dyes discharged from industries like textile, food processing, chemical, leather, dyestuff, dyeing, and pharmaceutical can negatively impact the natural ecosystem. Lentinus squarrosulus AF5, a strain of fungus, has been identified as a potential decomposer of these dyes. Proteomic analysis revealed differential protein expression in the strain when exposed to the dyes, indicating the important role of extracellular peroxidases in the decolorization process. UV-Visible, FTIR spectroscopic, HPLC, and LC-QTOF-MS analyses confirmed the degradation of the dyes by Lentinus squarrosulus AF5.

Summary: The batik industry generates colorful wastewater which is polluted by azo dyes. This study found that ozonation can effectively remove color from batik wastewater and degrade azo dyes. The toxicity of the dyes to microbial respiration was revealed through biodegradation tests, demonstrating the detoxification achieved by ozonation. Additionally, three-dimensional fluorescence spectroscopy analysis showed the accumulation of ozonolysis products.

Summary: This study reports the degradation activity of a bacterial consortium developed in the azo dye medium for multiple azo dye degradation, with most effective degradation observed under static condition. Analysis of the bacterial community revealed the presence of Proteobacteria, Bacteroidetes, and Firmicutes as dominant phyla. Genes predicted from metagenomic sequences were mapped onto the KEGG pathway to construct the Congo Red degradation pathway.

Summary: In this study, nitrogen-doped graphene (NG) was found to significantly accelerate the decolorization of methyl orange (MO) azo dye by sulfide. The stagnant time of MO decolorization was remarkably reduced in the presence of NGs, particularly those with graphitic nitrogen. Doping nitrogen improved the electron conductivity and enhanced the interactions between sulfide and carbon atoms bonded to graphitic nitrogen, leading to the formation of reactive intermediate polysulfides.
