Studies on in vitro bio-remediation potentials of four fungal strains isolated from the dye contaminated soil, namely Aspergillus candidus NCBT 104, Aspergillus erythrocephalus NCBT 106, Aspergillus fumigatus NCBT 107, and Cladosporium herbarum NCBT 147 were tested for bioremediation process of Azo-Red dye. Among the four isolates C. herbarum and A. erythrocephalus were more effective in the decolourization of red dye followed by A. candidus and A. fumigatus. Application of these two isolates (C. herbarum and A. erythrocephalus) in textile dye biodegradation process can be a promising method of exploiting these fungi as bioremediation agents. SDS-PAGE protein profile of these fungal isolates indicates different protein banding. This ensures direct biochemical mechanism involved in fungal metabolism during the process of bioremediation.
