چکیده انگلیسی
This study demonstrated electricity generation from rice straw without pretreatment in a two-chambered microbial fuel cell (MFC) inoculated with a mixed culture of cellulose-degrading bacteria (CDB). The power density reached 145Â mW/m2 with an initial rice straw concentration of 1Â g/L; while the coulombic efficiencies (CEs) ranged from 54.3 to 45.3%, corresponding to initial rice straw concentrations of 0.5-1Â g/L. Stackable MFCs in series and parallel produced an open circuit voltage of 2.17 and 0.723Â V, respectively, using hexacyanoferrate as the catholyte. The maximum power for serial connection of three stacked MFCs was 490Â mW/m2 (0.5Â mA). In parallelly stacked MFCs, the current levels were approximately 3-fold (1.5Â mA) higher than those produced from the serial connection. These results demonstrated that electricity can be produced from rice straw by exploiting CDB as the biocatalyst. Thus, this method provides a promising way to utilize rice straw for bioenergy production.
