Abstract

Nowadays, presence of the heavy metals in agricultural soils is becoming a serious environmental issue. The heavy metals in soils affect the microbial population such as bacteria and make them more resistant to these pollutants. In this research 11 soil samples from 11 point Lenjan agricultural areas around the Zayandehrood river in Isfahan were studied and 23 species of bacteria resistant to LEAD and CADMIUM from standard plate count method (SPC) were isolated. The isolated bacterial species belong to bacillus, sporolactobacillus, lactobacillus and arcanobacterium genuses. As a second step, by agar dilution method the minimum inhibitory concentration (MIC) and absorption ability of these bacteria were studied with atomic absorbtion spectrometer (Philip model PU 9100) and their resistance to other metals was also evaluated. The results of this study indicated that, environmental factors such as the presence of metals in soil and soil texture can affect the percentage of the RESISTANT BACTERIA and their tolerance toward the metals. In this study the effect of LEAD and CADMIUM on soils bacteria of Lenjan area was evaluated. Lenjan area is located about 20 kilometers at south west of Isfahan province. For the agricultural activates. This area is very intense, and the place is well known for its rice. In northeast of the Lenjan valley, the Irankouh mountain is located which is the place of Iran kouh zinc, LEAD and CADMIUM. mine, and since the soils in this area, are natural rich in these metals, the bacteria have been affected by the pollutants. From mine and probably by the irrigation water from Zayandehrood river.
