“…The results indicated that the SMFCs used in this study required less time to reach stable OCVs than MFCs inoculated with the same Andean soil and organic solid wastes [19,20]. This could suggest the better feasibility of these microorganisms to metabolize simple microbial fuels rather than complex ones.…”

“…In the SMFCs is was also observed that BOD concentration had a major influence on the OCV during the transient stage until day 7; although the OCV ratio is lower in between 5–7 d, afterwards an increasing stage was observed. Such an effect could be explained as the required period for adaptation of the microorganisms to the new conditions in the SMFCs [19,20], an endogenous metabolism as reported Chang et al [15] and the latency stage of the microbial growth related with the bioelectrogenic process. The high variability could also be related with the formation of microchannels in the soil matrix through which the SRWW was flowing during this stage, however, this effect was not studied in depth.…”

“…The anode and cathode were connected with two iron wires forming an external circuit. The OCV was measured by using a DT-832 digital multimeter [18,19]. The oxidant (O 2 ) in the cathode was supplied from the atmosphere during the elapsed time of the experiment.…”

“…Although the lower current output of MFCs is recognized as a limiting factor for their application, an energy management system for amplifying the voltage up to 5 V was reported [18]. Addionally, mixed cultures from wetland soils have also been used to degrade complex organic substrates considering their higher metabolic activity, where the output voltages were acceptable according to the reported in databases [19,20]. …”

Microbial fuel cells represent an innovative technology which allow simultaneous waste treatment, electricity production, and environmental monitoring. This study provides a preliminary investigation of the use of terrestrial Single chamber Microbial Fuel Cells (SMFCs) as biosensors. Three cells were created using Andean soil, each one for monitoring a BOD concentration of synthetic washed rice wastewater (SRWW) of 10, 100, and 200 mg/L for SMFC1, SMFC2 and SMFC3, respectively. The results showed transient, exponential, and steady stages in the SMFCs. The maximum open circuit voltage (OCV) peaks were reached during the elapsed time of the transient stages, according to the tested BOD concentrations. A good linearity between OCV and time was observed in the increasing stage. The average OCV in this stage increased independently of the tested concentrations. SMFC1 required less time than SMFC2 to reach the steady stage, suggesting the BOD concentration is an influencing factor in SMFCs, and SMFC3 did not reach it. The OCV ratios were between 40.6–58.8 mV and 18.2–32.9 mV for SMFC1 and SMFC2. The reproducibility of the SMFCs was observed in four and three cycles for SMFC1 and SMFC2, respectively. The presented SMFCs had a good response and reproducibility as biosensor devices, and could be an alternative for environmental monitoring.

“…Waste sludge also has been demonstrated to be an effective substrate in bioelectricity generation coupled with hydrogen production (Ge et al 2013;Choi & Ahn 2014). Fruit and vegetable wastes were employed as a substrate for microbes isolated from high Andean region in a single-chambered MFC (Logroño et al 2015). Choi and Ahn (2015) reported use of food waste leachate obtained from bio-hydrogen fermentation as a potential substrate toward enhanced electricity generation.…”

Bioelectricity production involves generation of electricity by anaerobic digestion of organic substrates by microbes. A microbial fuel cell (MFC) is a device that converts chemical energy released as a result of oxidation of complex organic carbon sources which are utilized as substrates by microorganisms to produce electrical energy thereby proving to be an efficient means of sustainable energy production. The electrons released due to the microbial metabolism are captured to maintain a constant power density, without an effective carbon emission in the ecosystem. The various parameters involved in MFC technology toward power generation include maximum power density, coulombic efficiencies and sometimes chemical oxygen demand removal rate which evaluates the effectiveness of the device. Application of microbes toward bioremediation at the same time resulting in generation of electricity makes MFC technology a highly advantageous proposition which can be applied in various sectors of industrial, municipal and agricultural Waste Management. Although the efficiency of MFCs in power generation initially was low, recent modifications in the design, components and working have enhanced the power output to a significant level thereby enabling application of MFCs in various fields including wastewater treatment, biosensors and bioremediation. The following review provides an outline about the components involved, working, modifications and applications of MFC technology for various research and industrial objectives. ARTICLE HISTORY
