Unlike many other pollutants, heavy metals are non-degradable and are persistent in the environment. Toxicity of heavy metals resulted from the interaction of metals with enzymes and inhibition of metabolic processes. Bioremediation is a technique used to alleviate toxicity of heavy metals. In this wok, Aspergillus niger was used to mitigate the toxic effect of lead (Pb) in Al-Gabal Al-Asfar farm, kalubiya, Egypt. Our results of growth, pigments, sugars and antioxidant system of Phaseolus vulgaris concluded that A. niger mitigated the toxicity of lead in bean.
