摘要

Heavy metal pollution of soil, water and air is one of the major issues many countries are facing. The fungi were isolated from the compost and compost yard soil and identified as Aspergillus clavatus, Aspergillus oryzae and Aspergillus fumigates. The dead biomass was used to study the sequestration of heavy metals from aqueous solution. Using dead biomass, the sequestration of Zn was more by A. fumigatus which was 89.08 mg g~(-1）, Cd and Pb by A. oryzae which was 86.25 and 93.39 mg g~(-1) respectively from the mixed metal solutions. Ni sequestration was ineffective from the mixed metal solution. Sequestration of Zn, Cd, Pb and Ni was more by A. fumigatus which was 19.32, 11.15, 18.88 and 18.33 mg g~(-1) respectively from individual metal solutions. The sequestration of heavy metals from mixed and individual metal solutions using mixed biomass was less. A technology can be developed for the removal of Zn by A. fumigatus, Cd and Pb by A. oryzae from mixed metal solutions and Ni by A. fumigatus from individual metal solutions. This will prove important application in the bioremediation processes for the control of heavy metal pollution and will also be of high industrial relevance for the environmental protection.
