Bioremediation of Toxic Heavy Metals Cr (VI) from Tannery Effluent using Micro-Organisms: Biotechnological Potential
Increased industrialization and human activities have impacted on the environment through disposal waste containing heavy metals. Heavy metals pollution of agricultural soil has been mainly due to the disposal of industrial wastewater, sewage and sewage sludge to agricultural land. Conventional methods for the removal of heavy metals from aqueous solutions are not economically and environmental friendly because it has produced massive quantity of toxic chemical compounds. Naturally fungi have a large variety of extracellular proteins, organic acids and other metabolites. Fungi can adapt in any ecosystems and any environmental conditions Interest in processes involving heavy metal uptake by microorganisms has increased considerably in recent years due to the biotechnological potential of micro-organisms in removing and/or recovery of metals.
