identification of bacteria resistant to heavy metals in the soils of isfahan province

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 andsediments 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 inhibitoryconcentration (mic) for the growth of the bacteria resistant to metals were determined. the dry cellularweight and the metal uptake rate were also defined for the bacteria resistant to metals.
