The effect of copper on the growth of Aspergillus niger was studied. In solid media, all the colonies grew faster in the absence of copper heavy metal, A. niger growth was luxuriant and the colonies were dark brown in positive control at the 10th day of the experiment. In contrast the growth was decreased gradually at 50, 100, 200, 300 , and 400 ppm respectively. In liquid media, Colonies grown for 10 days with different concentrations of copper heavy metal showed variation in fungal biomass when compared with positive control. An addition no growth was observed in high concentrations of copper heavy metal at 500 ppm.
