“…[72] Among different substrates, wastewater is a sustainable rich medium which can be treated by MFCs. There are several reports on electricity generation directly from complex organic wastewater such as municipal, [77] swine wastewater, [78] dairy wastewater, [79,80] slaughterhouse wastewater, [81] rice mill wastewater, [82] tannery wastewater, [58] cassava mill wastewater, [83] molasses wastewater, [84] refinery wastewater, [85] brewery wastewater, [86] winery wastewater, [87] chemical wastewater, [88][89][90] sulphide-rich wastewater, [91] landfill leachate, [92][93][94][95][96] food waste leachate, [97] azo dye, [98,99] and solid substrates such as rice straw. [100] MFCs also can be used for simultaneous removal of sulphide and nitrate from synthetic wastewater [101] and sulphate-sulphiderich wastewaters.…”

Microbial fuel cell (MFC) is a novel technology that can be used for electricity generation during oxidization of the organic substances presented in the substrate. To obtain a desirable performance, it is essential to understand the influential factors on the MFC. Among the numerous factors affecting the MFC performance, substrate, microorganisms and their metabolism, electron transfer mechanism in an anodic chamber, electrodes material and the shape of electrodes, type of membrane, operating conditions such as temperature, pH and salinity, electron acceptor in a cathodic chamber and geometric design of the MFC are considered as the most important factors. Among different substrates, wastewater is a sustainable rich medium which can be treated by MFCs. There are various types of exoelectrogenic bacteria presented in wastewaters which can oxidize organic matter and transfer electrons to the anode without using mediators. Like other microbial systems, optimum pH and temperature enhance the bacterial growth which can improve the MFC performance. Despite the negative effect of salt on microbial growth, higher salinity and ionic strength can increase the conductivity of substrate and therefore enhance MFC performance. Scaling up MFC is a controversial issue which needs a comprehensive understanding of these factors. By using new inexpensive materials for electrodes and membrane for manufacturing MFCs, a more cost-effective design for scalable wastewater treatment and high power generation can be achieved. Furthermore, MFC is a suitable candidate for bioremediation of contaminated groundwater. These factors and their impact on the MFC performance have been reviewed in the present survey.

Cassava mill effluent (CME) is generated during cassava processing into cassava flake or gari. The effluents affects the quality of the receiving environment such soil. It is could affect domestic animals such as goat and sheep when they ingest it, and retard normal growth and productivity of plants in the affected soil. This study evaluated amino acid and proximate composition of Saccharomyces cerevisiae cultivated in cassava mill effluents. S. cerevisiae used in this study was isolated from palm wine based on cultural, morphological, and physiological/biochemical characteristics. 10 ml of S. cerevisiae broth was inoculated into 100ml of sterile cassava mill effluents filtered with double muslin cloth. The medium was shaken intermittently between 7.00 to 19.00 hours' time interval. The medium was decanted and subsequently filtered using Whatman filter paper. The resultant biomass was washed with distilled water and re-filtered. The sludge/biomass recovered were oven dried. Amino acid and proximate composition of the yeast biomass produced was analyzed using spectrophotometer. Proximate composition was also analyzed following standard procedure. Result showed that the total essential amino acid (40.88 g/100 g) was slightly higher than the Food and Agricultural Organization/World Health Organization (FAO/WHO) standard for feed use. While the total non-essential amino acid (21.56 g/100 g) was lower than FAO/WHO limits. Mean proximate composition was 17.01% (crude protein), 7.34% (ash), 56.40% (carbohydrate) and 407.13 kcal/100 g (calorific value/energy content). The findings of this study showed that during fermentation of cassava mill effluents with S. cerevisiae an appreciable amount protein is enriched considering the fact that the substrate is a waste.

“…Microbial fuel cells (MFCs), which generate electrical energy by decomposition of organic substances, are based on this principle (1). Thus far, MFCs have been researched in various wastewaters sourced from domestic supplies (2e4), wine industries (5), breweries (6), paper recycling plants (7) cassava mills (8), and olive oil (9). MFCs using wastewater from starch processing have also been reported (10) and continuous electric generation from starch together with reduction of chemical oxygen demand using unclear assembled microorganism (4), but these study did not clarify the microorganisms in the wastewater.…”
