ABSTRACT

Due to increasing of population and industrial use of chemicals and manmade activity water resources are highly polluted with different harm full contaminants. Synthetic dyes are utilized extensively in various textile industries and found frequently in the effluent discharge of industrial wastes in excess quantity which can influence the ecological damage in the surrounding environment. Treatment is mandatory for those industrial effluents before being discharge. Mycoremediation by local fungal consortium is one of the sustainable and eco-friendly techniques for fast, realistic and complete degradation of Acid Blue-25 dye in to nontoxic metabolites. The present study deals with the isolation of dye degrading fungal strains from the dye amended soils. Irrespective of their molecular structure, during the decolorization process, observed that the Anthraquinone (Acid Blue-25) dye first undergo chromophore cleavage by anthraquinone reductase. It was confirmed by some of the released metabolites involved were analyzed by spectroscopy, TLC, HPLC, GCMS, LCMS, FTIR, and NMR. The derived intermediate metabolites are to be segregated in a specific pattern during the dye decolorization and degradation. But a few of the derivatives were fused to central metabolic pathway at the time of degradation. The phytotoxic impact of Acid Blue-25 along with the biodegraded compounds were proved that, the resulted and extracted derivatives were nontoxic in nature, stimulate in good germination of Phaseolus mungo seeds. Further, it is confirmed that the existing fungal consortium-10 was very efficient in decolorization and degradation of anthraquinone dyes by converting the toxic pollutants to non toxic which are eco-friendly.
