Microbial fuel cell has been considered a new emerging technology for renewable and sustainable electricity production. The energy can be extracted from organic waste materials which time independently increase in mass. In the present study, it was demonstrated that lignocellulosic material such as empty fruit bunch (EFB) can be used to produce electricity. Clostridium cellulolyticum and Bacilli E1 were used to activate EFB degradation and electricity generation respectively.  It was also demonstrated that the present EFB based MFC was affected in terms of power produced with much higher power was obtained at 37.5 ℃ with power value of 825 ± 3.08 mW/m2 compared to 25 and 50 ℃, which produced 756 ± 1.14 mW/m2 and 345 ± 1.78 mW/m2. At elevated temperature (50 ℃) showed decrease of power density value compared to lower temperature operated MFC, which is believed to be microbial metabolism dependent

To make the treatment of seafood wastewater more economical and sustainable, this study aims to examine electricity generation from seafood wastewater in MFC reactor. By supplying the MFCs with seafood wastewater, the maximum power density of 291.6 mW/m2 and CE of 20.3 % could be obtained. The substrate loss was attributed to diffusion of molecular oxygen from the cathode to the anode, which led to substrate conversion through aerobic respiration rather than electricity-producing pathway. This study provides a conceptual demonstration of seafood wastewater for electricity production using MFC technology.

This research studied the electricity production from organic wastes fermentation by microbial fuel cell by using a single chamber microbial fuel cell (SCMFC). Two sizes (1 L and 10 L) of simple SCMFC were fabricated by using a cylindrical plastic tank which anode compartment and cathode compartment separated by plastic plate with hole and covered with cotton fabric. The anode electrode contacted with organic matter and microorganisms where anaerobic reaction occurred to generate electron and proton. The electrons transferred through an external circuit while the protons diffused through the solution to the cathode electrode for reducing oxygen to water. From the study of the effect of different electrode types (carbon graphite rod, zinc metal, and copper metal) to the electricity generation using the SCMFC size 1 L in fermentation with synthetic sweetness solution (22%Brix) and the effective microorganism (EM) for 36 hrs, it found that the fuel cell which used copper metal as electrode produced electricity increasing over the times and has more efficient than the other electrode types. The study of electricity generation from organic waste fermentation by using the SCMFC size 10 L and using copper metal as electrode, the results showed that the fermentation of pineapple waste produced the current density, potential density, and power density higher than the fermentation of bananas and the fermentation of food garbage with EM. An optimal period of time for the production of electricity from this microbial fuel cell is the first five days of fermentation that the cells has voltage »500 mV, the current density 25.52 mA m-2, potential density 104.69 V m-2 and power density 12.59 mW m-2, and then decline over time five days (120 hrs). Moreover the bio-liquid fertilizer and the residues from the fermentation can be further used in agricultural because of the nutrient content (N, P, K), organic carbon and organic material contents available.

Infant Stage

In the last 10 years, the microbial fuel cell (MFC) has been extensively studied worldwide to extract energy from wastewater via electricity generation. More recently, a merged technique of embedding MFC into a constructed wetland (CW) has been developed and appears to be increasingly investigated. The driving force to integrate these two technologies lies in the fact that CWs naturally possess a redox gradient (depending on flow direction and wetland depth), which is required by MFCs as anaerobic anode and aerobic cathode chambers. No doubt, the integration of MFC with a CW will upgrade the CW to allow it to be used for wastewater treatment and, simultaneously, electricity generation, making CWs more sustainable and environmentally friendly. Currently, published work shows that India, China, Ireland, Spain, Germany and Malaysia are involved in the development of this technology although it is in its infant stage and many technical issues are faced on system configuration, operation and maximisation of electricity production. This paper aims to provide an updated review and analysis of the CW-MFC development. Focuses are placed on the experience gained so far from different researchers in the literature and further research directions and proposals are discussed in great detail.

The microbial fuel cell (MFC) is an innovative technology that was initially designed to harness energy from organic waste using microorganisms. It is striking how many promising applications beyond energy production have been explored in recent decades. In particular, MFC-based biosensors are considered to be the next generation biosensing technology for environmental monitoring. This review describes recent advances in this emerging technology of MFC-based biosensors, with a special emphasis on monitoring of biochemical oxygen demand and toxicity in the environment. The progress confirms that MFC-based biosensors could be used as self-powered portable biosensing devices with great potential in long-term and remote environmental monitoring.

Effect Of Glucose

Microbial Fuel Cell (MFC) technology utilizes bacterial growth in carbon-containing substrates to generate electricity. For direct production of electricity, this MFC operates aerobically at the cathode and anaerobically at the anodes. This study tested the effect of glucose (10 %, 20 %, 30 %, 40 % and 50 % (w/w)), on the growth of bacteria, and then subsequent electricity production after 144 hours of the incubation period. Obvious substrate degradation rates (SDE) were detected in MFC fed with initial glucose concentration of 20 % (w/w) and 30 % (w/w) at 46.29 % and 40.27 %, respectively. The former generated 0.808 mW and the later was 0.736 mW. Glucose, being a basic component for growth of electrogenic bacteria influenced electricity generation. Higher the glucose concentration supplemented to the sludge, the more saturated the substrate was. Hence, inhibited the bacterial growth, and reduced electricity generation.
