Abstract

In this research the total of resistant bacteria to heavy metals communities were studied in agricultural soils.The effect of four heavy metals of Lead (2mM), Copper (5mM), Cadmium (0.5 mM) and Arsenic (5mM) on microbial population of ten agricultural soils with irrigation from Zayandehrood river were studied and then the Minimum Inhibitory Concentration (MIC) for 38 bacteria isolates were determined.The dry cellular weight, the amount of metals sorption inside the bacteria and the multi-resistance to few metals for the isolate resistant the bacteria were determined. A great proportion of the isolates were resistant %45, %8 %50 and %40 to lead,copper, cadmium and arsenic respectively. Also the MIC arsenic was the highest amount but the lowest percent absorption was determined for arsenic. The majority of the tested strains (%92.1) were multiple metal resistant, with tri-metal resistance at the major pattern (%36.8). The highest patterns resistance existed between lead,copper and arsenic (%15.7).
