Abstract :
Background and Objective: Industrial waste is considered as the most important environmental pollutants that contain significant amounts of heavy metals are high salt density.Biotechnology removal of heavy metals from industrial wastewater Babkargyry proved the ability of microorganisms developing in this field as an appropriate and efficient.In this study, the ability of strains of bacteria isolated from sediments of Lake Urmia Halomonas longate IBRC-M10433 for the removal of cadmium was investigated. The aim of this study was to optimize the removal of cadmium by bacterial environment was Halomonas longate IBRC- M10433. Method: Design of Experiments Taguchi method to determine the optimum conditions relative to environmental factors such as Ammonium chloride (NH4Cl) as a source of nitrogen, and phosphate potassium (K2HPO4) as a source of phosphorus and cadmium concentrations in biological removal of cadmium was studied by the bacterium Halomonas longata IBRC- M10433. Findings: The optimum conditions for absorption of potassium phosphate at a concentration of 3.0 g/L, cadmium 100 mg/L, Ammonium chloride 2 g/L, at 37 °C and pH 7, respectively. Level 1 means that 3.0 g of potassium phosphate absorption biological factors. Discussion and Conclusion: Due to high costs and environmental problems conventional methods to remove heavy metals, biological removal technique is effective and affordable. Use halophilic bacteria in biological treatment with high power absorption of heavy metals are useful.
