Evaluation of electricity generation by microbial Fuel cell from hypersaline indian soda lake
India has faced challenge for more electricity generation and alternative for the traditional sources and due to the lack and depletion of primary sources. Microbial Fuel Cells (MFCs) is an alternative source of the sustainable and renewable energy.The objective of this study was to investigate the electricity generation from the haloalkalophilic bacterium isolated from Lonar soda crater (India). Aerobic, haloalkaliphilic bacteria were isolated and characterized from sediment and water samples. A total twenty eight bacterial culture were isolated, of which ARS4 was selected for the further MFC was investigated. The two-chamber MFCs were used to conduct experiments. The MFC was constructed and measure the electricity generation after various intervals, 387mV was electricity was generated after 1h, but after 48h the electricity generation dramatically decreased to 229mV. The effect of salt on MFC was also studied, NaCl enhanced electricity generation compared to KCl, indicating requirement of NaCl for bacterium ARS4 MFC. Supplement of glucose, increased electricity generation was found to be increases (170mV). Our results also suggest that seeking for and isolating novel bacteria that are more halophilic and alkaliphilic from Lonar crater could be a new strategy to generate bioelectricity from MFCs.
