Abstract: Biosorption technology has gained tremendous importance in bioremediation and microbes could become the cheapest tool in detoxification of effluent streams. Aspergillus sp. isolated from the soil sample collected from the area near Hyderabad Metal Plating Industry, I.D.A, Balanagar, Hyderabad, India have been investigated in this study. The growth kinetics of Aspergillus sp. was studied by growing the fungi at different concentration of iron ranging between 0.2mM – 12 mM (Ferrous sulphate). The culture showed considerable inhibition of growth with iron when compared to the metal free controls. The maximum amount of iron was observed in the medium containing 3.0 mM concentration and further increase in the metal concentration was found to increase metal adsorption. Transmission Electron Microscopy analysis revealed the adsorption of iron nanoparticles on the cellwall.
