چکیده مقاله :
زمینه و هدف: پساب های صنعتی به عنوان مهم ترین آلاینده های محیط زیستی محسوب می شوند که حاوی مقادیر فراوان از فلزات سنگین وتراکم بالای نمک می باشند .بیو تکنولوژی حذف فلزات سنگین از پساب های صنعتی با بکارگیری توانایی میکروارگانیسم ها به عنوان روشی مناسب و بهینه دراین زمینه در حال توسعه است. شناسایی باکتری های مقاوم به فلزات سمی و استفاده آن ها در فرآیند حذف زیستی تکنیکی پیچیده و مفید است. در این مطالعه توانایی سویه باکتریHalomonaselongata IBRC-M10433 جداشده از رسوبات دریاچه ارومیه در حذف فلز کادمیوم مورد بررسی قرار گرفت. هدف از این مطالعه بهینه سازی شرایط محیطی حذف فلز کادمیوم توسط باکتری Halomonas elongata IBRC- M10433بود. روش بررسی : طراحی آزمایش به روش تاگوچی به منظور تعیین شرایط بهینه نسبی فاکتورهای محیطی مانند کلریدآمونیوم (NH4Cl) به عنوان منبع نیتروژن، فسفات پتاسیم (K2HPo4) به عنوان منبع فسفرو غلظت کادمیوم در حذف زیستی کادمیوم توسط باکتری Halomonas elongata IBRC- M10433 مورد مطالعه قرار گرفت. آنالیز داده ها با استفاده از نرم افزارکامپیوتری Qualitek-4 انجام شد و اهمیت نسبی هریک از عوامل تعیین گردید. یافته ها : شرایط بهینه جذب در غلظت فسفات پتاسیم 3/0 گرم بر لیتر، کادمیوم100میلی گرم بر لیتروکلریدآمونیوم 2گرم بر لیتردر دمای 37 درجه سانتی گراد و pH 7 تعیین شد. سطح 1 فسفات پتاسیم یعنی 3/0 گرم بر لیترموثرترین فاکتور درجذب زیستی بود. بحث و نتیجه گیری: با توجه به هزینه بالا و مشکلات محیط زیستی روش های مرسوم حذف فلزات سنگین، حذف زیستی تکنیکی موثر و مقرون به صرفه می باشد. استفاده از باکتری های نمک دوست نسبی در پالایش زیستی با قدرت بالای جذب فلزات سنگین مفید می باشد.
چکیده انگلیسی:
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.
