ABSTRACT

Heavy metals are systemic toxins with specific neurotoxic, nephrotoxic and phototoxic effects. Heavy metals can directly influence behaviour by impairing mental and neurological function, influencing neurotransmitter production and utilization and altering numerous metabolic processes. In this present study Aspergillus niger and Aspergillus flavus were identified and inoculated with chromium to analyse the capability of those microorganism in bioremediation. The results revealed that chromium level decreased in culture media. It was also observed that Aspergillus niger removes the chromium at higher rate when compared to that of Aspergillus flavus.

Keywords: Aspergillus niger and Aspergillus flavus.
