The complex nature of leather dyes makes them resistant to conventional biological treatment processes. Fungi have proven to be a promising alternative due to their resilience in harsh environments and ability to remove dyes through bio-sorption, biodegradation, and bioaccumulation mechanism. This study explored the potential of unique fungal strains, Brown fungus (F1) and Green Fungus (F3) isolated from tannery solid waste to remediate leather dye biologically. A synthetic dye solution of acid brown was tested in the micoremediation process. Factors influencing dye removal by micoremediation were investigated using batch culture technique. Maximum dye removal achieved for the initial dye concentration of 50 mg/L and culture incubation time of 7 days for both the fungi. Optimal pH of dye removal was found to be 4 for F1 and 5 for F3. At the optimal experimental conditions fungus F3 remediated more dye in comparison with fungus F1 with the removal percentages of 92.32% and 88.24% respectively. Various carbon media to support fungal growth for dye removal were also tested where Potato Dextrose Broth (PDB) achieved the highest removal. The fungal species F1 and F3 demonstrated dye removal efficiencies of 52.03% and 55.13% respectively at a dilution factor of 10, for real wastewater from leather dyeing operation showcasing its practical applicability in industrial wastewater treatment. Alcohol wash was identified as the best decolorizing solution for fungus reusability where dry fungal biomass of F1 was better reusable than F3. The SEM studies provided insights into the structure of fungi involved in the micoremediation process. This study reveals that, the novel fungal isolates have a potential for micoremediation of leather dyes at its optimal growth conditions for both synthetic dye solution and tannery dyeing waste liquor.
