“…These mediators whether internal or external will be responsible for the electron transfer from the bulk microorganisms to the anode surface. The electron transfer in the mediated electron transfer is higher than that in the DET [4,[44][45][46][47][48][49][50][51].…”

“…Microbial fuel cells (MFCs) are among the fast-growing microbial electrochemical systems (MESs) that offer a promising way for simultaneous wastewater treatment and electricity production [1][2][3]. Although MFCs showed promising features such as simultaneous wastewater treatment and electricity generation, low sludge production, wide range of substrates and operating at room temperature, the low power output and high cost especially that of the Pt cathode are the main challenges facing their commercialization [4][5][6].…”

“…The exo-electrogenic microorganisms that can be used in MFCs can be a prokaryote or eukaryote. Although prokaryotic microorganisms showed promising results in the MFCs and a lot of research has been carried out using them due to their ease in the electron transfer mechanism, yeast, as a eukaryote, attracted researchers' attention and was extensively studied as a biocatalyst in MFCs [4][5][6].…”

“…Beberapa bakteri diketahui dapat mentransfer elektron secara langsung, seperti Rhodoferax ferrireducens (Chauduri dan Lovley, 2003). Adapun jenis ragi Saccharomyces cerevisiae dan bakteri Escherichia coli memerlukan senyawa tambahan berupa senyawa berwarna yang berfungsi sebagai mediator elektron untuk memediasi proses transfer elektron, seperti metilen biru (MB) (Gunawardena et al, 2008;Ieropoulos et al, 2005).…”

ABSTRAKMicrobial fuel cell (MFC) merupakan salah satu teknologi sel bahan bakar alternatif yang dapat diperbarui. MFC memanfaatkan proses oksidasi senyawa kimia oleh biokatalis untuk menghasilkan energi listrik daya rendah. Tujuan dari penelitian ini adalah mengetahui kinerja MFC dengan dan tanpa mediator elektron metilen biru (MB) menggunakan biokatalis Acetobacter aceti dan substrat glukosa agar diperoleh energi listrik. Metode yang dilakukan adalah peremajaan kultur A. aceti, persiapan inokulum, persiapan reaktor MFC, persiapan media MFC dengan substrat glukosa 2% dengan dan tanpa mediator MB, pencuplikan secara periodik, penentuan kurva pertumbuhan, arus, potensial, kerapatan daya, energi, kadar glukosa dan tingkat keasaman (pH). Hasil penelitian menunjukkan bahwa MFC dengan mediator menghasilkan kuat arus sebesar 0,040 mA, potensial 878 mV, kerapatan daya 0,395 mW/cm 2 , energi maksimum 3,685 kJ, pemanfaatan glukosa 93,02% dan pH akhir 3,33, sedangkan MFC tanpa mediator menghasilkan kuat arus 0,035 mA, potensial 773 mV, kerapatan daya 0,290 mW/cm 2 , energi maksimum 2,434 kJ, pemanfaatan glukosa 90,16% dan pH akhir 3,24. Perolehan kerapatan daya pada kedua jenis MFC masih tergolong kecil dan tidak berbeda secara signifikan. Berdasarkan hasil penelitian dapat disimpulkan bahwa penggunaan mediator MB hanya berpengaruh terhadap perolehan potensial pada MFC dengan kondisi perlakuan yang diterapkan dalam penelitian ini.Kata kunci: Microbial fuel cell, Acetobacter aceti, metilen biru, mediator elektron THE EVALUATION OF METHYLENE BLUE AS ELECTRON MEDIATOR IN MICROBIAL FUEL CELL WITH ACETOBACTER ACETI BIOCATALYST ABSTRACTMicrobial fuel cell (MFC) is one of alternative renewable fuel cell technologies. MFC utilizes oxidation processes of chemical compounds by biocatalyst to produce low power electrical energy. The objective of the present study was to investigate the performance of MFC with and without methylene blue (MB) as electron mediator utilizing Acetobacter aceti as biocatalyst and glucose as substrate to generate electrical energy.

“…In mediator-based MFCs mediators such as neutral red, methylene blue, thionine, humic acid or sulphate/sulphide (Park and Zeikus, 2000;Scott and Murano, 2007;Gunawardena, Fernando and To, 2008;Rossi, Fedrigucci and Setti, 2015), depending on the species of microorganism used, are added which act as intermediaries between the microorganisms cell membrane and the anode to transfer electrons. But most available mediators are expensive and toxic.…”

Microbial fuel cells (MFCs) are bio-electrochemical devices that exploit microorganisms for producing electricity from a variety of materials, including complex organic waste and renewable biomass. In this study, the heterotrophic microbe, Bacillus firmus was used as the active bacterial component with synthetic waste waters for bio-electricity production. Three identical mediatorless and membraneless single chambered microbial fuel cells (MFCs) without catalyst was fabricated with different carbon source and operated in batch mode. The performance of these MFCs with glucose, hydrolyzed potato peel and hydrolyzed cyanobacterial biomass substrates were comparatively evaluated. Among these substrates hydrolyzed cyanobacterial biomass was found to be the favorable substrate for electricity production whereas potato peel was unable to construct a well-established MFC. The maximum power density of 16.46mW/m2 at 62.48mA/m2 was achieved using cyanobacterial mass as the substrate. A current density of 53.47mA/m2 appeared to characterize the maximum power produced from a polarization test was 5.85mW/m2 for glucose substrate.
