Summary: Wastewater produced by textile industries is difficult to treat due to its large volume, toxicity, and variable composition. In this comprehensive study, two native bacterial consortia were found to degrade pure textile effluent without pre-treatment or the addition of nutritional sources, reducing TOC, COD, and pH. One consortium was more efficient in decolorization and COD reduction, while the other showed better performance in reducing toxicity. Diversity analysis revealed no significant loss of diversity during degradation.

Summary: This study investigated the decolorization efficiency of selective reactive azo dyes by non-adapted Lysinibacillus sphaericus MTCC 9523 in optimized conditions, with visual color changes and spectroscopic analysis confirming decolorization. HPLC analysis showed differences in retention time between control and treated samples, supporting biodegradation, while GC-MS analysis revealed the chemical identities of metabolites and predicted the metabolic pathways of degradation for each dye. Overall, the use of adapted and non-adapted microbes is a promising, cost-effective and time-saving green strategy for the biodegradation of textile effluent containing azo dyes.

Summary: This study isolated and identified a bacterial strain with the potential to decolorize and degrade Reactive Black 5 (RB5). The strain, identified as Bacillus albus DD1, showed a 98% removal of RB5 within 38 hours under optimum conditions. Kinetic and thermodynamic analyses revealed that the decolorization reaction was a first order non-spontaneous reaction, and the degradation of RB5 occurred through the cleavage of the azo bond.

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: Textile industries produce wastewater with harmful azo dyes that are known to be carcinogenic and mutagenic. This study evaluates the potential use of enzyme immobilized biochar for removing azo dyes from real and simulated textile effluents. The results show that the enzyme immobilized system can achieve high removal efficiency for individual azo dyes in the simulated effluent and for one dye peak in the real effluent. The presence of metabolite in the real effluent indicates the degradation of the dye. Therefore, enzyme immobilized biochar system can be used for simultaneous adsorption and degradation of toxic azo dyes from real effluents.

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: The development of a novel oleaginous consortium, OYC-Y.BC.SH, using three yeast cultures has shown great potential for lipid production, textile dye/effluent removal, and lignin valorization. The consortium exhibited high lipid productivity, lipase activity, and decolorization efficiency, making it valuable for biodiesel production and bioremediation of textile effluents. Toxicological studies also support the use of OYC-Y.BC.SH for detoxification of industrial dyeing effluents.

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: The study found that Escherichia coli showed a high potential in degrading the dye, and certain physicochemical parameters significantly affected its degradation capability. The proposed mechanism of dye degradation by Escherichia coli was deduced from the analysis of the metabolites. These findings are of great importance for the treatment of textile effluents containing azo dyes.

Summary: This review focuses on the integrations of various advanced oxidation processes (AOPs) with biodegradation for the treatment of textile azo dyes, aiming to reduce the processing cost and improve the degree of mineralization. Results show that ozone treatment alone is the most efficient in decolorization, while all three AOPs independently offer varied and inadequate COD reduction. The integration of AOPs with biodegradation further reduces COD and TOC levels, and has the potential to significantly reduce treatment costs. The review suggests further research in sequencing chemical and biological routes for complete detoxification of textile azo dyes.
