“…A major materials approach is the surface modification (Cheng and Logan, 2007;Scott et al, 2007), which focuses on improving colonization potential for bacteria at the electrode surface. It has been suggested that surface modification can significantly reduce the formation time of an electroactive biofilm; however, the long-term performance of the biofilm remains unaffected by the surface treatment (Kumar et al, 2013).…”

The performance of primary and secondary electroactive biofilms grown on layered corrugated carbon (LCC) electrodes was studied over a period of several months. With an average projected current density of 6.7 mA cm −2 , the studied secondary electroactive biofilms outperformed the primary biofilms (3.0 mA cm −2 ) over the entire experimental period. At the same time, both, primary and secondary biofilms, exhibited a constant Coulomb efficiency of about 89%. The study further illustrates that three-dimensional electrodes such as LCC allow a sustained long-term performance without significant decrease in electrode performance.

“…The surface state of the electrodes has been found to be an important parameter affecting MFC performance, either because it affects the electrochemical properties of the electrode [36][37][38] or through its effect on biofilm formation. Ammonia gas treatment of anodes or their oxidation in sulphuric acid has been reported to affect bacterial adhesion or microbial communities in anode biofilms [36,39].…”

Treatment of dairy wastes with a microbial anode formed from garden compost

Garden compost has already been identified as a source of efficient electro-active (EA) biofilms. The work described here consisted of lixiviating the compost and then using the leachate as a microbial source. This procedure gave promising results for the treatment of yogurt waste (YW) in a microbial fuel cell (MFC). Experiments performed in MFC set-ups were compared with electrochemical cells under polarization at ?0.1 V versus SCE. Different parameters were tested to optimize the microbial anode. Preliminary acclimation of the compost microbial flora to YW was revealed to be unnecessary. Forming biofilms firstly in pure leachate before exposing them to YW showed that high concentrations of this type of substrate were detrimental to current generation. Pre-treatment of the electrode by pre-adsorbing YW led to a 10-fold increase in the current density. The highest current densities were obtained at 40 and 60°C, revealing the diversity of electro-active microorganisms coming from soils. Values up to 1,450 mA m -2 were reached at 40°C.

“…Potensial listrik yang diperoleh dari hasil degradasi sudah cukup baik, karena senyawa hasil degradasi limbah seperti NO3-/ NO2 serta NO 3 -/N 2 memiliki potensial antara 0,34-0,74V. Faktor yang menentukan nilai elektrisitas pada MFC ini adalah jenis substrat, kondisi operasi sistem, luas area, tipe elektroda dan jenis mikroorganisme (Scott et al 2007). …”

Jurnal Pengolahan Hasil Perikanan Indonesia. 20(2): 296-304. AbstrakMicrobial Fuel Cell (MFC) merupakan salah satu teknologi alternatif yang dapat mengubah energi kimia menjadi energi listrik melalui reaksi katalitik menggunakan mikroorganisme. Teknologi ini dapat diaplikasikan pada penanganan limbah, salah satunya limbah cair perikanan yang mengandung beban limbah organik yang cukup tinggi. Tujuan penelitian ini untuk mengukur kinerja sistem MFC pada limbah cair perikanan dalam menghasilkan biolistrik sekaligus menurunkan beban limbahnya menggunakan jenis elektroda yang berbeda yaitu alumunium, besi, karbon grafit serta kombinasi alumunium dan karbon grafit. Metode penelitian ini terdiri dari tiga tahap, yaitu pembuatan limbah cair perikanan, pembuatan alat MFC satu bejana dan pengukuran elektrisitas limbah. Hasil elektrisitas selama 120 jam pengamatan secara keseluruhan mulai dari alumunium, besi, karbon grafit hingga kombinasi alumunium dengan karbon grafit berturut-turut adalah 0,23V, 0,17V, 0,19V, dan 0,34V. Hasil penelitian menunjukkan bahwa sistem MFC mampu menurunkan rata-rata total Nitrogen yaitu 61%, BOD 30,11%, COD 59,34%, dan total amonia nitrogen 12,45%. Peningkatan biomassa lumpur aktif terjadi pada akhir pengamatan melalui nilai Mixed Liquor Suspended Solid (MLSS) dan Mixed Liquor Volatile Suspended Solid (MLVSS) masing-masing 7.066,67 mg/L dan 6.100 mg/L.

The technology can be implemented for wastewater handling such as fish processing wastewater which contains highly in organic substances. The research objective was to measure the performance of MFC system using fishery processing wastewater in order to generate bioelectricity and to reduce its organic pollution load within a different material of the electrode. The electrode materials used were aluminum, iron, carbon graphite, and also the combination of aluminum and carbon graphite. The research carried out in three phases: production of fishery wastewater, assembly of MFC single chamber system and measurement of the bioelectricity produced. The bioelectricity power resulted during 120 hours of observation were 0.23V for aluminum, 0.17V for iron, 0.19V for carbon graphite, and 0.34V for the combination between aluminum and carbon graphite averagely. The MFC system can also decrease the organic load parameter of wastewater as much as total Nitrogen was 61%, BOD 30.11%, COD 59.34%, and total Nitrogen Ammonia 12.45%. The increasing of activated sludge biomass occurred on the last observation with MLSS and MLVSS v...
