Improving electricity generation from wastewater (DW) by using olive mill wastewater (OMW) was evaluated using single-chamber microbial fuel cells (MFC). Doing so single-chambers air cathode MFCs with platinum anode were fed with domestic wastewater (DW) alone and mixed with OMW at the ratio of 14:1 (w/w). MFCs fed with DW+OMW gave 0.38 V at 1 kΩ, while power density from polarization curve was...

Renewable energy is an increasing need in our society. Microbial fuel cell (MFC) technology represents a new technology for the regeneration of electricity from what would otherwise be considered waste and can be a vital candidate for energy in this respect. Electricity directly generated by using bacteria while accomplishing wastewater treatment in MFC processes. The present study deals with p...

Biofuel cells generate electricity through biological processes. Conventional microbial fuel cells (MFCs) operate by converting organic substrates, such as glucose, acetate, starch, and lactate, to electrical bioenergy through microbial oxidation processes [1-3]. A typical MFC consists of an anodic and a cathodic chamber with electrodes partitioned by a proton exchange membrane (PEM) or a catio...

Microfibrillated cellulose (MFC) employed as reinforcement of polymeric matrices can increase elastic modulus, stiffness and strength a composite. In this work, the assessment mechanical, thermal properties tensile tests assisted by digital image correlation (DIC) was performed for curaua fiber MFC-reinforced polylactic acid (PLA) composites function MCF content. First, MFC incorporated into PL...

Microbial fuel cells have gained popularity in recent years due to its promise in converting organic wastewater into renewable electrical energy. In this study, a membrane-less MFC with a biocathode was developed to evaluate its performance in electricity generation while simultaneously treating wastewater. The MFC fed with a continuous flow of 2g/day acetate produced a power density of 30 mW/m...

Electricity generation was examined from proteins and a protein-rich wastewater using a single chamber microbial fuel cell (MFC). The maximum power densities achieved were 354 +/- 10 mW/m2 using bovine serum albumin (BSA) and 269 +/- 14 mW/m2 using peptone (1100 mg/L BSA and 300 mg/L peptone). The recovery of organic matter as electricity, defined as the Coulombic efficiency (CE), was comparabl...

The microbial fuel cell (MFC) is an ecologically friendly alternative energy source. Due to the typically limited electron transfer in MFC systems, co-biocatalysts are necessary enhance their performance. Enzymes used as due superior ability generate energy, and system known enzymatic (EMFC). One of substrates that may be bagasse waste extracted from sugarcane. Saccharo­myces cerevisiae enzyme ...

Several carbon substrates were tried, including glucose commercial, pro analysis glucose, commercial sugar, and yeast extract - peptone d (YPD) medium to improve the efficiency of single chamber microbial fuel cell (MFC). The power production various electron donors was investigated using baker Saccharomyces cerevisiae. Voltage density generation used establish pattern substrate use. In additio...

Microbial fuel cells (MFC) with 30% wet-proofed air cathodes have previously been optimized to have 4 diffusion layers (DLs) in order to limit oxygen transfer into the anode chamber and optimize performance. Newer MFC designs that allow close electrode spacing have a separator that can also reduce oxygen transfer into the anode chamber, and there are many types of carbon wet-proofed materials a...

Electro-Fenton reactions can be very effective for organic pollutant degradation, but they typically require non-sustainable electrical power to produce hydrogen peroxide. Two-chamber microbial fuel cells (MFCs) have been proposed for pollutant treatment using Fenton-based reactions, but these types of MFCs have low power densities and require expensive membranes. Here, more efficient dual reac...
