Microbial fuel cells (MFCs) are of increasing interest as bioelectrochemical systems for decomposing organic materials and converting chemical energy into electricity. The main challenge for this technology is that the low power and voltage of the devices restricts the use of MFCs in practical applications. In this paper, a power management system (PMS) is developed to store the energy and expo...

The suppression of methanogens affects the performance of Microbial Fuel Cells (MFCs), but its degree of importance is application dependent. In terms of Coulombic Efficiency (CE), avoiding methanogenesis is essential for MFC type volatile fatty acid (VFA) sensors but less critical for scaled-up MFCs removing COD from real wastewater. To study the suppression of methanogenesis, different H-type...

EcoBot I is a robot developed in the IAS Lab that uses Microbial Fuel Cells (MFC) as the ‘live engine’ and glucose as the fuel. This prototype robot employs no other form of conventional power supply and it proves the concept of autonomy whilst at the same time performing photo-taxis. Recent experiments conducted in our lab, employing two different techniques, have suggested that the power outp...

Current reliance on fossil fuels is unsustainable due to pollution and finite supplies. Microbial cell factories serve as promising alternatives renewable energy resources. Microorganisms generate electricity in their metabolism; act as catalysts for converting the chemical energy into electricity. In Microbial Fuel Cell (MFC), electrons provided by microorganisms flow through an electrical ext...

This work is motivated by the experimental design problem of optimizing the power output of nano-enhanced microbial fuel cells. Microbial fuel cells (MFCs) (Bond and Lovley, 2003; Fan et al., 2007; Park and Zeikus, 2003; Reguera, 2005) use micro-organisms to break down organic matter and generate electricity. For a particular MFC design, it is critical to optimize the biological energetics and ...

Submit Manuscript | http://medcraveonline.com treatment approach [1,2]. Biofuel cells can be divided into two main categories: enzymatic fuel cells (EFC) and microbial fuel cells (MFC). In both, oxidation of a given “fuel” occurs at the anode combined with a reduction of final electron acceptor at the cathode [3] . The potential difference between the two electrodes is the driving force of the ...

Biotechnological utilization of microbial processes normally starts with the discovery, investigation, and understanding of naturally occurring microbial reactions. Biomolecular tools can help us, not only to gain better understanding of protein reactions; they also enable us to influence reaction properties. For efficient practical applications, modern biological techniques allow us to tailor ...

Microbial Fuel Cells (MFCs) are capable of producing electricity while cleaning wastewater. This novel technology can replace energy-consuming aerobic treatment even if low effluent concentrations are demanded. The goal of this work is to optimize a MFC-based wastewater treatment process. A MFC mathematical model, which accounts for co-existence of methanogenic and anodophilic microbial populat...

Microbial fuel cells (MFCs) were embedded into constructed wetlands to form microbial fuel cell coupled constructed wetlands (CW-MFCs) and were used for simultaneous azo dye wastewater treatment and bioelectricity generation. For the first time, the effects of different substrate biomass on the performance of CW-MFCs were studied. Group A had the highest substrate biomass of 0.453 g VSS per L, ...
