“…If the electrode is used as an anode, it must be made of a conductive, biocompatible, and chemically stable material. The material for the corresponding anode is usually carbon [7]. In addition, based on other studies, a Microbial Fuel Cell with a two-chamber type uses a salt bridge or cation exchange membrane which is an essential component in the fuel cell system.…”

Palm oil liquid waste has been successfully developed to produce bio-electricity with a dual chamber-microbial fuel cell system. This study utilized the Lactobacillus bulgaricus bacteria as a support for the substrate samples prepared in the anode chamber. Meanwhile, in the cathode chamber, KMnO4 electrolyte solution is used as an electroactive species that can capture electrons well. In addition, salt bridges fabricated from agar have a role as ion-exchange media in microbial fuel cells. The test results showed that the best performance was obtained in samples of palm oil wastewater with the addition of 10% Lactobacillus bulgaricus (LS/B-10) bacteria with current, voltage, and power density values of 0.9640 mA, 0.6760 V, and 248.04 mW/m2, respectively. The MFC system has also been proven to be able to reduce COD (Chemical Oxygen Demand) and TSS (Total Suspended Solid) levels, with the results of a reduction percentage of 42.6% and 7.2%, respectively, in the LS/B-10 variable treatment. All test results show that palm oil wastewater with the addition of Lactobacillus bulgaricus bacteria is promising for producing bioelectricity with a microbial fuel cell system.

Microbial fuel cells make it possible to generate electricity by eliminating and using wastewater components. For these purposes, the most viable microbial associations in microbial fuel cells. The presence of strains of different microorganisms allows you to consume a much wider range of compounds. Multicomponent makes them more resistant to the negative effects of stressful environmental factors. An example of such associations are silt sediments of biological treatment plants. The purpose of this work was to create a new microbial association. Microbial association was formed from previously isolated strains from activated sludge from the petrochemical plant, Micrococcus luteus and Serratia marcescens. Model wastewater was taken as substrates. The generation of electricity was carried out in microbial fuel cell models that we developed. These designs allowed access to the contents of microbial fuel cells without violating sterility and anaerobic conditions in the anode chamber. In the experiments, the voltage, current in microbial fuel cells were measured and the power was calculated. Experiments have shown high electrogenic activity when working together with Micrococcus luteus and Serratia marcescens cohosts for a good variety of the proposed bioagent complex. The search and isolation of energy-efficient strains and the compilation of a new consortium from them will not only increase the current output in microbial fuel cells to more significant values, but also bring such microbial fuel cells into the category of promising developments for alternative energy. This work was supported by the Ministry of Education and Science of the Russian Federation (project RFMEFI58317X0060 “Bioremediation and bioconversion of waste using a complex of photosynthetic organisms and heterotrophs in aerobic and anaerobic conditions with bioenergy generation”).
