Heavy metal tolerance of fungal and bacterial isolates, and their functional groups following biosorption

Heavy metal contamination still prevails due to improper discharge of effluents from industries, mining activities, agricultural and domestic sources. Hence, the objectives this study were isolate bacteria fungi with high potentials for biosorption Cd(II), Pb(II), Cr(III) Ni(II) explore their functional groups. Bacteria able grow in presence 0.1% selected heavy metals isolated enumerated using nutrient agar potato dextrose agar, respectively. The isolates then screened abilities withstand concentrations metals. After screening, potential identified used percentage study. Fourier transform infrared spectroscopy was compare spectra groups elaborated by control stressed isolates. Bacterial counts higher than fungal across soil samples. Screening revealed that tolerated Pb(II) better Cd(II). as Ochobactrum intermedium, Bacillus subtilis, Aspergillus niger Cunninghamella bertholletiae. common flasks C. bertholletiae, A.
