Isolation and Identification of Cadmium-Resistant Bacteria from Wastewater Treatment Plant of Shahinshahr in Isfahan

Article excerpt

Background: Heavy metals enter the environment through industrial activities and among the most toxic heavy metal in the environment are the Cadmium.This metal can eventually reach the tissues of humans and animals. In this study, the Cadmium-resistant bacteria from effluent of wastewater treatment plant of Shahinshar were investigated.

Methods: Sampling of effluent of the wastewater treatment plant of Shahinshahr was taken and the level of Cadmium samples was measured by the atomic absorption device. For the removal of cadmium-resistant bacteria, serial dilutions of the samples were prepared and the dilutions were cultured on the PHG II culture medium, containing density 0.5 mM cadmium nitrate.Then, bacterial identification was done by morphological and biochemical tests and their molecular identification are underway.

Results: In this study, the level of cadmium presents in wastewater samples was equals to 0. …
