Water pollution caused by the textile industry is a significant environmental concern due to the discharge of synthetic dyes and chemicals that are resistant to degradation. This study aimed to treat textile dye effluent using specific microbial strains. Two bacterial strains (Bacillus and Pseudomonas) and two fungal strains (Aspergillus and Penicillium) were isolated and evaluated for their dye degradation efficiency. The bacterial strains achieved a maximum decolorization of 91-95% (Bacillus) and 89.25% (Pseudomonas), while the fungal strains demonstrated complete decolorization, reaching 100% efficiency. Optimization experiments revealed that the ideal conditions for bacterial dye degradation were pH 7, temperature 37 °C and glucose as the carbon source. In contrast, optimal fungal degradation occurred at pH 6, temperature 25 °C using glucose as the carbon source. These findings underscore the significant potential of microbial strains in the biodegradation of textile dyes and support their application as efficient, sustainable and eco-friendly alternatives to conventional wastewater treatment technologies. This study also highlights the feasibility of scaling up this approach for practical use in industrial effluent treatment systems.
