Abstract

 
 
 Synthetic dyes have a repugnant effect on the aquatic ecosystem and their venomous components have to be removed from the effluent before their exemption. The decolourization of synthetic dyes by fungi is emerging as an effective and clean technology. Fungal-abetted processes are amongst the finest approaches for transformation, degradation and decolourization of recalcitrant dyes. This study was carried out to find out the qualities of textile effluents with the estimation of physicochemical parameters of textile effluents, isolation and identification of fungi. The physicochemical parameters were demarcatedas per the standards prescribed by CPCB.15 fungi isolated from textile effluent and effluent- contaminated soil samples were evaluated to decolourize textile dyes - Reactive Red ME-4B and Brill blue-R. 9 different fungal species were further identified as Aspergillus spp, Penicillium spp, Mucor, Curvularia spp, Helmintho sporium spp, Fusarium spp, Trichoderma spp, Rhizopus, spp and Alternaria spp by 18S rRNA Sequencing. These 9 isolates with potential decolourization were assessed via primary and secondary decolourization. The study also showed that Penicillium spp, Aspergillus spp and Trichoderma spp are highly efficient in decolorizing (85.41, 98.80and83.23 %) in 6 days as used in the present investigation. The results have demonstrated the potential of the fungal isolates for the treatment of dyes contaminated textile effluent.
