Abstract

The disposal of untreated wastewater from textile industries poses significant environmental challenges resulting from the occurrence of toxic colorants and heavy metal contaminants. This experimental study investigates the biodegradation of methyl orange and Congo red dyes using bacterial mixed cultures isolated from textile effluents. Four bacterial strains, including Escherichia spp., Staphylococcus spp., Pseudomonas spp. and Enterobacter spp., were evaluated for their decolorization efficiency. Methods included sample collection, dye stock preparation, bacterial isolation and decolorization studies, with optimization for temperature, pH and bacterial consortia. Results showed Pseudomonas spp. exhibited highest decolorization efficiency for methyl orange (93.42%) and Escherichia coli showed the highest for Congo red (88.63%). Optimal conditions were room temperature and pH 7 for Pseudomonas spp. Bacterial consortia were more effective in degrading single dyes than mixed dyes. FTIR analysis confirmed dye breakdown post-treatment. This study demonstrates the potential of bacterial strains for bio remediating textile dye pollutants, offering an eco-friendly, cost-effective solution for industrial effluents.
