چکیده
The current importance of energy emphasizes the use of renewable resources (such as wastewater) for electricity generation by microbial fuel cell (MFC). In the present study, the native sulfate-reducing bacterial strain (R.gh 3) was employed simultaneously for sulfurous component removal and bioelectricity generation. In order to enhance the electrical conductivity and provision of a compatible bed, a complex electrode structure based on stainless steel-304 was prepared. Next, the electrode was coated with a composite of graphite and activated carbon solution. A new approach associated with increasing bacterial population was studied using two electron acceptors composed of iron and sulfate for respiration of sulfate-reducing bacteria. Finally, according to the maximum living cell number (nM = 20 ´108 cell ml-1) and the conditions of the bioreactor including the highly efficient anode electrode, a higher current generation (2.26 mA for the new structure as compared to 1.73 and 1.29 mA for graphite rod and carbon paper, respectively) was observed in the culture media.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
