Rice Straw as a Potential Biomass for Generation of Bioelectrical Energy Using Microbial Fuel Cells (MFCs)

초록

Continuous use of fossil fuels has exacerbated environmental issues as well as threatens the insecurity of global energy. In an effort to reduce dependency on non-renewable energy sources, lignocellulosic biomass is considered as the potential source of renewable energy in recent years. In this context, rice straw has a vital role to play. In this article, electricity generation from rice straw in two-chambered microbial fuel cells was investigated. The microbial fuel cell produced the open circuit voltage of 0.705 +/- 0.007 V. The microbial fuel cell produced the working voltage of 0.601 +/- 0.02 V (1,000 Omega) with 1 g/L rice straw. The maximum power density of 190 +/- 13.6 mW/m(2) was obtained with 1 g/L rice straw corresponding to the maximum current density of 506 +/- 54.47 mA/m(2). The results of this study can contribute to improving understanding of and optimizing electricity generation from rice straw in microbial fuel cells.
