Abstract

Use of microorganisms for removing mercury is an effective technology for the treatment of industrial wastewaters and can become an effective tool for the remediation of man-impacted coastal ecosystems with this metal. In this study, seven types of mercury resistant bacteria were separated from industrial waste and minimum inhibitory concentration (MIC), were determined for these bacteria. Results showed that two strains of bacteria, which isolated from waste water detergent plants, are more resistant to mercury and able to grow at the presence of 52 ppm of mercuric chloride. These bacteria could be used for biological treatment of mercury in contaminated wastewater.
