Abstract
Industrial discharges, in the form of effluent or wastewater is one of the biggest problems causing serious environmental pollution. Bioremediation is an emerging technology for removing the heavy metals from the contaminated environment. In the present study, industrial effluent samples from five different sites of Bhusan Steel Plant (BSP) and National Thermal Power plant Corporation (NTPC) were collected. Heavy metal analysis of effluent samples showed the presence of a number of metals like Chromium(Cr), Zinc (Zn), Manganese (Mn), Lead (Pb), Cobalt (Co), Copper (Cu), Nickel (Ni), and Cadmium (Cd), from which Mn, Cr, Pb and Zn were beyond the permissible limit. Five different fungal strains were isolated and identified as Penicillium sp., Aspergillus fumigatus, Aspergillus sp., Penicillium adametzi and Aspergillus niger. Out of which, Aspergillus fumigatus was found to remove maximum Cr from the culture broth in comparison with other isolates. Hence, from the present study it can be concluded that indigenous fungi can be a novel tool for bioremediation. Further studies need to be carried out on biosorption of toxic heavy metals through fungi.
