ABSTRACT
Metals are non-biodegradable and recurrent in the environs. Heavy metals tolerant fungiwere isolated from refuse dumpsite soil using pour plate method. These fungiwere identified as Aspergillus niger, Penicillium chrysogenumandRhizomucor sp. The fungal isolates were screened for cadmium (Cd), lead (Pb) and zinc (Zn) with concentration of 200ppm, 400ppm and 600ppm. Aspergillus nigerand Penicillium chrysogenumshowed high tolerance for the metals in contrast to the control. The fungiwith high tolerance were used for biosorption study. However, Penicillium chrysogenumshowed higher lead removal or biosorption potential of 1.07ppm, 3.35ppm and 4.19ppm as compared with Aspergillus nigerwith lead removal of 0.67ppm, 3.11ppm and 3.79ppm at 5th, 10thand 15thday respectively. One-way Analysis of Variance was used to interpret the data generated from the biosorption study which revealed that there was no significant different (p>0.05)between the lead removal of Aspergillus nigerandPenicillium chrysogenumon the 5thday but there was significant difference (p<0.05)in the lead removal of Aspergillus nigerand Penicillium chrysogenumon the 10thand 15thday. This study suggests the use of these fungal isolates for removal and biotreatment of heavy metal contaminated and polluted environment.
