The study combined anaerobic composting of untreated rice straw with V-shaped microbial fuel cell (V-MFC) to investigate the hydrolysis of lignocellulose and electricity generation of V-MFC. Due to the configuration for V-MFC, protons that be generated by the process of lignocellulose degradation could be accumulated with composting liquid at the bottom of V-MFC, and increased the contact area ...

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...

Abstract Background Microbial fuel cell (MFC) technology is a promising sustainable future energy source with renewable and abundant substrate. MFC critical drawbacks are anode surface area limitations electrochemical loss. Recent studies recommend thick biofilm growth due to the synergetic effect between microbial communities. Engineering prospect of MFC. In this study, electrode jacket dish (...

Bioelectrochemical systems such as microbial fuel cells (MFCs) are promising new technologies for efficient removal of organic compounds from industrial wastewaters, including that generated from swine farming. We inoculated two pairs of laboratory-scale MFCs with sludge granules from a beer wastewater-treating anaerobic digester (IGBS) or from sludge taken from the bottom of a tank receiving s...

The attachment of microorganisms to electrodes is of great interest for electricity generation in microbial fuel cells (MFC) or other applications in bioelectrochemical systems (BES). In this work, a microcosm of the acidic ecosystem of Río Tinto was built and graphite electrodes were introduced at different points. This allowed the study of electricity generation in the sediment/water interfac...

Microbial fuel cells (MFCs) are remarkable "green energy" devices that exploit microbes to generate electricity from organic compounds. MFC devices currently being used and studied do not generate sufficient power to support widespread and cost-effective applications. Hence, research has focused on strategies to enhance the power output of the MFC devices, including exploring more electrochemic...

Changes in metabolism and cellular physiology of facultative anaerobes during oxygen exposure can be substantial, but little is known about how these changes connect with electrical current output from an operating microbial fuel cell (MFC). A high-throughput voltage based screening assay (VBSA) was used to correlate current output from a MFC containing Shewanella oneidensis MR-1 to carbon sour...

Application of microbial fuel cells (MFCs) to wastewater treatment for direct recovery of electric energy appears to provide a potentially attractive alternative to traditional treatment processes, in an optic of costs reduction, and tapping of sustainable energy sources that characterizes current trends in technology. This work focuses on a laboratory-scale, air-cathode, and single-chamber MFC...

Graphene-modified materials have captured increasing attention for energy applications due to their superior physical and chemical properties, which can significantly enhance the electricity generation performance of microbial fuel cells (MFC). In this review, several typical synthesis methods of graphene-modified electrodes, such as graphite oxide reduction methods, self-assembly methods, and ...

concurrent renewable energy production and wastewater treatment are two main reasons for using microbial fuel cells (mfcs). in this study, real wastewater was used for treating and power generation by air cathode microbial desalination cells (acmfc). the total duration of voltage generation by acmfc was about 151.9 ±23.2 h. the maximum voltage produced from municipal wastewater treatment was 27...
