ABSTRACT

 

The present research work explores the potential of fungi isolated from the soil samples previously polluted with textile dyes. Soil samples from textile industriy were collected and analysed. All the isolated fungal cultures were studied for their dye tolerent nature in Potato Dextrose Agar amended with 150 mg/ml of reactive red dye HE3B. Further, the selected strains were tested for their dye decolorization efficiency in liquid media and the percent decolorization was calculated by the values of the optical density measured at 520 nm in the spectrophotometer. The fungal isolates showing moderate zone indicating decolourization of the dye were selected as Aspergillus niger, Aspergillus fumigatus, Aspergilus terreus and Penicillium sp. Among all the fungi Aspergilus was a dominant species recorded and maximum decolorization (92.1%) was achieved by Aspergillus niger, followed by Aspergillus fumigatus, Aspergilus terreus and Penicillium sp. This study has confirmed the potential of the test fungi in the decolorization of reactive dye and offer an easy, cost effective method and could be used for the future analysis of their performance in the biotreatment of textile effluent
