Dye Decolorization of Textile Dyes by Using Aspergillus fumigatus Isolated from Marine Soil

Fungi are commonly employed widely in bioremediation because of their capacity to break down a wide variety of contaminants. Due to sophisticated treatment techniques, the successful use of decolorization of textile dyes to treat high concentrations of industrial effluents will be a milestone. The main area of interest in study is the decolorization of such toxic components. Aspergillus fumigatus, the most prevalent fungus, is utilised in this study to decolorize the dye. The dye-containing PDA is optimised and used to inoculate the fungus. After 5 days, the dye decolorization in changed PDA is visible. In PDB broth Aspergillus fumigatus showed maximum 90.6 ± 0.52% decolorization of Coomassie Brilliant Blue, 60 ± 0.81% decolorization of Congo red, 59.5 ± 0.25% decolorization of Gelatin violet, 55.6 ± 0.52% decolorization of Malachite green and 52.52 ± 0.50% decolorization of Brilliant green. When compared to these 5 dyes Coomassie Brilliant Blue has undergone maximum decolorization by Aspergillus fumigatus after five days of incubation. Different carbon, nitrogen, temperature, and pH levels were employed as the optimal conditions to decolorize textile dyes. Using maltose as a carbon source, A. fumigatus demonstrated the highest dye decolourization (94.10.17%) among the carbon sources. Using yeast extract as a nitrogen source, A. fumigatus had the highest dye decolourization (97.10.17%) of all the nitrogen sources tested. among the various temperatures applied. With room temperature, A. fumigatus displayed the highest colour decolourization (89.30.62%). A. fumigatus demonstrated the greatest dye decolorization (92.10.17%) at pH 7, which was employed. The findings make it abundantly clear that fungal isolates were capable of effectively decolorizing the textile colours. The only efficient method for completely managing the pollution produced by the textile and dyestuff industries is dye decolorization using microorganisms because it is both economical and environmentally benign. To create a workable alternative technique for the treatment of textile wastewater, however, more and more research and development efforts are required.
