“…These devices are actively used for environmental analysis-determination of BOD of aqueous media [3], total water toxicity [4], and levels of various substances in industrial waste, including food waste [5]. A microbial fuel cell (MFC) is an energy conversion device that utilizes electrogenic bacteria capable of producing electrical energy directly from organic waste while removing pollutants from the environment [6]. Waste from vegetable farms and food industry enterprises contains large amounts of polysaccharides, polyphenols, sugars, carotenoids, and glycosides.…”

A novel conductive composite based on PEDOT:PSS, BSA, and Nafion for effective immobilization of acetic acid bacteria on graphite electrodes as part of biosensors and microbial fuel cells has been proposed. It is shown that individual components in the composite do not have a significant negative effect on the catalytic activity of microorganisms during prolonged contact. The values of heterogeneous electron transport constants in the presence of two types of water-soluble mediators were calculated. The use of the composite as part of a microbial biosensor resulted in an electrode operating for more than 140 days. Additional modification of carbon electrodes with nanomaterial allowed to increase the sensitivity to glucose from 1.48 to 2.81 μA × mM−1 × cm−2 without affecting the affinity of bacterial enzyme complexes to the substrate. Cells in the presented composite, as part of a microbial fuel cell based on electrodes from thermally expanded graphite, retained the ability to generate electricity for more than 120 days using glucose solution as well as vegetable extract solutions as carbon sources. The obtained data expand the understanding of the composition of possible matrices for the immobilization of Gluconobacter bacteria and may be useful in the development of biosensors and biofuel cells.

“…In general, the efficiency and practicability of MFC were greatly affected by the power output. Cathode contributed to a significant influence on the power output of MFC and most of the bare electrode materials possessed slow kinetic in the oxygen reduction reaction (ORR) [4]. Platinum-based IOP Publishing doi:10.1088/1755-1315/1135/1/012007 2 catalysts were widely used in recent research due to their efficient ORR activity.…”

Microbial fuel cell (MFC) has attracted extensive attentions over the past decade because it able to treat wastewater and generate bioelectricity concurrently. However, the development of cost-effective cathodic catalysts to enhance the oxygen reduction reaction was vital for practical implementation. The effect of cathodic catalyst of tin (IV) oxide (SnO2) on the removal of synthetic wastewater and power generation in a baffled MFC was explored. SnO2 was synthesized using tin (IV) pentahydrate and sodium hydroxide through a hydrothermal method. SnO2 was characterized using X-ray diffractometer before applied on the carbon plate (CP) to identify the phase composition and crystal structure, respectively. Results indicated that the chemical oxygen demand removal of synthetic wastewater was increased up to 18 % under the presence of SnO2. The application of SnO2 on CP has significantly increased the oxygen reduction reaction reactivity in the cathodic chamber.

“…One of such methods is microbial fuel cell (MFC) technology. MFCs are energy conversion devices containing electrogenic bacteria capable of harvesting electrical energy directly from organic waste while simultaneously removing pollutants [ 5 ]. Oxidation of organic substrates by microbes takes place in the anode compartment and leads to the formation of carbon dioxide, protons and electrons [ 6 ].…”

Microbial fuel cells (MFCs) are a variety of bioelectrocatalytic devices that utilize the metabolism of microorganisms to generate electric energy from organic matter. This study investigates the possibility of using a novel PEDOT:PSS/graphene/Nafion composite in combination with acetic acid bacteria Gluconobacter oxydans to create a pure culture MFC capable of effective municipal wastewater treatment. The developed MFC was shown to maintain its activity for at least three weeks. The level of COD in municipal wastewater treatment was reduced by 32%; the generated power was up to 81 mW/m2 with a Coulomb efficiency of 40%. Combining the MFC with a DC/DC boost converter increased the voltage generated by two series-connected MFCs from 0.55 mV to 3.2 V. A maximum efficiency was achieved on day 8 of MFC operation and was maintained for a week; capacitors of 6800 µF capacity were fully charged in ~7 min. Thus, G. oxydans cells can become an important part of microbial consortia in MFCs used for treatment of wastewaters with reduced pH.
