Abstract: Decolourization of textile dyes from fungi Aspergillus flavus, Fusarium oxysporum, Fusarium moniliforme and Trichoderma harzianum isolated from the soil samples around the textile distillery industries of Nanjangud, Karnataka, India were tested for their efficacy in decolourization of Textile dyes, Orange3R, Blue3R, YellowGR, BlackRL and T blue. It was found that all the four fungal species were found to be efficient in decolouring textile dyes. Among the four fungal species A. flavus was more efficient followed by F. oxysporum, F. moniliforme and T. harzianum. The percent decolourization of black RL and T blue was more when compares to Orange3R, Blue3R and YellowGR.
