Industrial discharges, in the form of effluent is one of the greater problems causing serious environmental pollution. Pulp and paper mills are categorized as one of the 12 most polluting industries containing heavy metals like Cu, Zn, Cd, Pb, Cr and Mn. The removal and recovery of heavy metals from effluent is indispensable for the protection of environment. Biological methods such as bioaccumulation and biosorption of heavy metals provide an alternative to physical and chemical methods for waste water treatment. In the present study, A.flavus and A.fumigatus isolated from pulp and paper mill sludge showed tolerance and accumulation of toxic metals from synthetic medium and paper mill effluent. Effect of heavy metal ions on fungal growth in terms of their biomass (dry weight) was determined and conformed energetic fungal growth after increasing the concentration of Pb2+ and Zn2+ point out the importance of these two fungi for bioremediation. Heavy metal reductions were found significant (P<0.001) in paper mill effluent treated with A.flavus and A.fumigatus, and accumulated maximum Pb followed by Cu, Zn, Cd, Cr and Mn metals were noticed.
