Set Up

Generating electricity using microbial fuel cell powered by benthic mud collected from two locations in Akure was carried out. The locations were Riverbed of FUTA and Apatapiti area of Akure. This was achieved by building anode and cathode containers connected together by a salt bridge and an external circuit was made to transfer the electrons from the anode to the cathode. Bacteria and fungi were isolated from the benthic mud for eight days using standard microbiological techniques. Lactobacillus plantarum, Escherichia coli, Bacillus subtilis, Enterobacter aerogenes, Trichoderma sp, Mucor sp and Alterania sp; Lactobacillus plantarum, Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, Myrothecium sp and Geotrichum candidum were bacteria and fungi isolated from the benthic mud of Apatapiti area and Riverbed of Futa, Akure respectively. This was used for the generation of electricity using unsterilized mud sample and the control setup was sterilized mud from same source. The set-up was monitored every 24hrous to determine the voltage and current generated. The pH, concentration and temperature were measured. The temperature remains constant throughout the experiment. The set-up were operated at a normal temperature of 27oC and 29oC for Riverbed of FUTA and Apatapiti area of Akure respectively. The peak voltage was between 182.5V and 192.5V and current produced from the main set-up was between 0.3A to 0.53A for Futa river bed while for Apatapiti area of Akure the peak voltage and current were 192.5V and 0.3A respectively. Higher microbial population, current and voltage were observed to be generated in River bed of Futa than Apatapiti area. The difference in the voltage and current and the control set-up shows that anaerobic microorganisms are capable of producing electricity from microbial fuel cell under appropriate conditions.

Rapid consumption of renewable energy resources has led to development of an alternative source of energy. Fuel cell technology is a reliable and sustainable source of energy which was developed. Microbial fuel cell is a type which uses active micro-organisms as catalysts for production of electricity. The micro-organisms degrade the organic substrate to release protons and electrons which generate a potential difference across the cell. Our study focused on the generation of electricity from human urine using microbial fuel cell system. Specific bacteria were used as inoculum at anaerobic anode chamber and salt solution was supplied at aerobic cathode. The chambers were connected using salt bridge which would facilitate ion transfer. This made the system cost effective. The potential difference generated was measured using digital multi-meter.

Waste generated by both agro based industries and domestic units have high nutrient contents to support microbial growth, these wastes are indiscriminately dumped and constitutes environmental and health hazards. Some of these wastes can be used to grow some bacterial species in microbial fuel cell to generate bioelectricity. The Microbial fuel cell is a device where the bacteria can grow on one electrode, they breakdown organic matter and release electrons from it. The bacteria can do this by keeping them separate from the oxygen, and when they release those electrons it creates a potential between the electrodes of about half a volt and voltage times current is power, and that is how power is generated from it. The waste materials used in this work are banana peels. Bacterial isolates that are used from the sewage and hay soil all within Gandhigram institute, Gandhigram. Microscopic characterization of the isolates by Gram reaction revealed the Gram negative and Gram positive and Biochemical test showed that the three isolated organisms were Escherichia sp., Pseudomonas sp, Bacillus sp. Microbial fuel cell were fabricated with a two plastic bottles as anode and cathode chamber. The electrode used were Aluminium mesh. A 3.75% sodium chloride, 2.2% agar salt bridge connected the chambers. The organism and banana peel as biocatalyst. Result that was monitored showed the maximum of 86mV at 24 hours reading respectively

Constructed a two-chambered microbial fuel cell (MFC) and a similar abiotic fuel Cell----Steel fuel cell (SFC), studies the influence of elimination effect about various variables (anode material , size of salt bridge and so on) to the nitrate. The experiment indicated that the elimination efficiency of MFC to the nitrate is 71.46% equally, SFC is 67.99%, and degeneration speed of nitrate is 8mg nitrate/L/day approximately. It has confirmed that MFC and SFC is one highly effective method on elimination nitrate, and the elimination effect of MFC to nitrate is better than SFC.
