Abstract

During this research, bacteria resistant to metals were evaluated in the soil of Isfahan Province.
According to the sampling locations the soils are classified as agricultural soils, non-agricultural soils and
sediments of the Zayanderood Riverbank. The bacteria resistant to lead (2 mM), copper (5 mM), cadmium
(0.5 mM) and arsenic (5 mM) were identified, and then during later stages, the minimum inhibitory
concentration (MIC) for the growth of the bacteria resistant to metals were determined. The dry cellular
weight and the metal uptake rate were also defined for the bacteria resistant to metals.
