Effect of Various Factors on Cadmium Tolerance of Cupriavidus sp. HMT 35

Heavy metal pollution poses a serious threat to environment disturbing the natural flora and fauna of the nearby area. These contaminated sites can provide efficient pool of microbial diversity to be used for bioremediation of contaminated sites. The present study was conducted to isolate a potential cadmium tolerant strain. Cupriavidussp. HMT 35 strain was isolated from heavy metal contaminated soil collected from Zawar, Udaipur, India. Cupriavidussp. HMT 35 was found cadmium tolerant and showed fairly higher MIC value (1500?g/ml). Cupriavidussp. HMT 35 showed maximum cadmium tolerance in nutrient broth adjusted to pH 7.0 at 37? C after an incubation period of 48h. The isolate has a potential to tolerate high concentration of cadmium. It can be further explored for its possible use in remediation and restoration of contaminated land.
