Biological Removal of Cadmium by Halomonas elongate IBRC-M10433 in Different Conditions: Optimization by Taguchi Statistical Approach

The biological removing method is cheap and safe for the environment. The Cadmium is toxic and harmful for the environment; therefore, the biological removing programs were developed for deletion of this metal from waste. Detection of persisting bacteria to toxic metals and using them for removing heavy metal from arouses environments and wastewaters is very important. In this study the ability of Halomonas elongate IBRC-M10433 bacterium was achieved from Urmia Salt Lake was tested to remove of Cadmium in wastewaters. For achievement optimised of different environmental factors such as Cadmium, Glucose and salt for removal of Cadmium from H. elongate IBRC-M10433, we used Taguchi method. Results from this study showed that H. elongate IBRC-M10433 persists to Cadmium metal. The largest Cadmium removal (85%) was seen in the culture that contains 50 ppm Cadmium, Glucose 10 g/L and NaCl 200 g/L.
