In this study, Ponceau S dye, which is one of the hazardous dyes found in industrial wastewater, was examined for hydrogen production in single chamber-free membrane-free microbial electrolysis cells at different concentrations (10-40 mg L -1 ). A gas content analysis (hydrogen, carbon dioxide, and methane) was measured daily using gas chromatography to determine the effects of the Ponceau S on hydrogen production levels. Hydrogen was successfully produced in the presence of Ponceau S dye, but the gas production levels were affected by the concentrations of Ponceau S. The maximum hydrogen production was measured as 18 mL at a concentration level of 20 mg L -1 . Decolorization ratios of Ponceau S were in the range of 85-100%. Hydrogen production rates increased in the presence of Ponceau S (20 mg L -1 ); however, yield (%) of the production decreased when compared to the control group. The percentage of COD removal was 94.78% in the presence of 40 mg L -1 of Ponceau S. In conclusion, hydrogen can be generated using wastewaters contaminated with azo dyes such as Ponceau S, and decolorization of the dye can be achieved, simultaneously.

Microbial fuel cells offer a technology for simultaneous biomass degradation and biological electricity generation. Microbial fuel cells have the ability to utilize a wide range of biomass including carbohydrates, such as starch. Sago hampas is a starchy biomass that has 58% starch content. With this significant amount of starch content in the sago hampas, it has a high potential to be utilized as a carbon source for the bioelectricity generation using microbial fuel cells by Clostridium beijerinckii SR1. The maximum power density obtained from 20 g/L of sago hampas was 73.8 mW/cm2 with stable cell voltage output of 211.7 mV. The total substrate consumed was 95.1% with the respect of 10.7% coulombic efficiency. The results obtained were almost comparable to the sago hampas hydrolysate with the maximum power density 56.5 mW/cm2. These results demonstrate the feasibility of solid biomass to be utilized for the power generation in fuel cells as well as high substrate degradation efficiency. Thus, this approach provides a promising way to exploit sago hampas for bioenergy generation.

A microbial fuel cell (MFC), a novel technology, is a biochemical catalyzer system that can convert the chemical energy of materials to bioelectric energy. This system can serve as a unique device for the treatment of wastewater. Based on this knowledge, we decided to study the bioenergy production ability of Actinomycete and microbial isolates in industrial glass factory wastewater as the decomposers of organic materials in this wastewater and the generation of Voltage and current in two batches and fed-batch conditions. At the most favorable condition maximum of 1.08 V (current 3.66 mA and power density 2.88 mW/m2), 81.2% chemical oxygen demand was obtained for a fed-batch system. Also, the outcomes of MFC’s essential parameters, for example, pH and TDS, were studied before and after the performance of MFC. The results showed a significant decrease after the operation of the MFC. To realize which Actinomycete were the most powerful bioelectric microorganism, the growth curve and electricity performance of three kinds of Actinomycete was selected. Results showed that the C2 would be more potent because its Voltage of 0.224 V and current of 1.187 mA possessed by it would result in an excellent power density of 141.42 mW/m2.

Bahan bakar fosil merupakan salah satu bentuk energi yang banyak digunakan dan mendukung hampir semua aspek energi. Bahan bakar fosil merupakan bahan bakar yang tidak dapat diperbarui, karena proses pembentukannya membutuhkan waktu jutaan tahun. Microbial Fuel Cell (MFC) menghasilkan energi listrik menggunakan substrat dari komponen organik maupun anorganik, menggunakan sel mikroba sebagai katalis. Struktur dari MFC terdiri dari kompartemen anoda yang berisi sel mikroba, mediator, dan elektroda yang terpisah dari kompartemen katoda. Kompartemen katoda terdiri atas elektroda dan penerima elektron (elektron akseptor). Anoda dan katoda terhubung via sirkuit dan aliran elektron dari sel mikroba ke penerima elektron katoda. MFC dapat menggunakan substrat yang bervariasi, termasuk air limbah. Penggunaan gula sebagai substrat MFC yang menggunakan sel kapang dapat menghasilkan energi maksimum sebesar 374.4 mW/m2. Di masa depan, MFC sangat mungkin digunakan sebagai sumber energi listrik yang paling sustainable. Dalam kondisi terkontrol, MFC dapat menghasilkan energi listrik yang lebih efektif dibandingkan dengan baterai yang perlu diisi ulang sebelumnya.

The over-exploitation of fossil fuels and their negative environmental impacts have attracted the attention of researchers worldwide, and efforts have been made to propose alternatives for the production of sustainable and clean energy. One proposed alternative is the implementation of bioelectrochemical systems (BESs), such as microbial fuel cells (MFCs), which are sustainable and environmentally friendly. MFCs are devices that use bacterial activity to break down organic matter while generating sustainable electricity. Furthermore, MFCs can produce bioelectricity from various substrates, including domestic wastewater (DWW), municipal wastewater (MWW), and potato and fruit wastes, reducing environmental contamination and decreasing energy consumption and treatment costs. This review focuses on recent advancements regarding the design, configuration, and operation mode of MFCs, as well as their capacity to produce bioelectricity (e.g., 2203 mW/m2) and fuels (i.e., H2: 438.7 mg/L and CH4: 358.7 mg/L). Furthermore, this review highlights practical applications, challenges, and the life-cycle assessment (LCA) of MFCs. Despite the promising biotechnological development of MFCs, great efforts should be made to implement them in a real-time and commercially viable manner.

Abstract Background Microbial fuel cells ( MFCs ) are potentially advantageous as an energy‐efficient approach to wastewater treatment; however, the quality of the MFC effluent has not been well addressed. In this study, a membrane bioelectrochemical reactor ( MBER ) was developed through integrating hollow‐fiber ultrafiltration membranes into a tubular MFC to improve the effluent quality . Results This MBER was operated with an acetate solution or domestic wastewater (primary effluent) for more than 200 days. The MBER removed 43–58% of total chemical oxygen demand ( COD ) from the acetate solution and achieved 30–36% coulombic efficiency. When treating the wastewater, the MBER was able to maintain almost 90% COD removal and an effluent turbidity <1 NTU . A strategy of periodic backwash and membrane relaxation led to a slow increase in the transmembrane pressure ( TMP ) from zero to 15 kPa in more than 40 days at hydraulic retention time ( HRT ) 36 h. However, both lower HRTs and high organic loading rates rapidly increased the transmembrane pressure . Conclusion A proof of concept of an MBER was presented and shown to be effective in contaminant removal. Preliminary energy analysis suggests that the MBER could theoretically produce sufficient energy from the acetate solution to support the pumping system. These results demonstrate the feasibility of the MBER concept and the challenges for further development of the MBER system. © 2012 Society of Chemical Industry

In a bioelectrochemical system, the energy content in dissolved organic matter can be used to power the production of hydrogen peroxide (H2O2), which is a potentially useful chemical at wastewater treatment plants. H2O2 can be produced by the cathodic reduction of oxygen. We investigated four types of gas-diffusion electrodes (GDEs) for this purpose. A GDE made of carbon nanoparticles bound with 30% polytetrafluoroethylene (PTFE) (wt./wt.C) to a carbon fiber paper performed best and catalyzed H2O2 production from oxygen in air with a coulombic efficiency of 95.1%. We coupled the GDE to biological anodes in two bioelectrochemical reactors. When the anodes were fed with synthetic wastewater containing acetate they generated a current of up to ∼0.4 mA/mL total anode compartment volume. H2O2 concentrations of ∼0.2 and ∼0.5% could be produced in 5 mL catholyte in 9 and 21 h, respectively. When the anodes were fed with real wastewater, the generated current was ∼0.1 mA/mL and only 84 mg/L of H2O2 was produced.

Microbial fuel cells (MFCs) are increasingly attracting attention as a sustainable technology as they convert chemical energy in organic pollutants to renewable electricity. Anthracene is a polycyclic aromatic hydrocarbon (PAH) that presents a high pollution and health risk. In this study, anthracene degradation with electricity production in Single – chamber air cathode MFC was investigated with respect to values of its biodegradation and MFC performance using different inocula combinations (Anaerobic sludge (AS), Pseudomonas putida (PP), Geobacter sulfurreducens (GS), Shewanella putrefaciens(SP), mixed cultures, and combinations thereof). All the inocula showed high potentials for anthracene degradation efficiency and power density, ranged 41 – 98 % within 120 – 216h and 110.08 – 156.06 mW/m2, respectively. The best overall performing inoculum was anaerobic sludge supplemented with P. putida (AS+PP), having a degradation rate, degradation efficiency, COD removal, maximum power density and coulombic efficiency of 38 μM/d, 98 %, 83 %, 156.06 mW/m2 and 21, respectively. Effect of initial anthracene concentration was also investigated. Results indicated that increasing of initial anthracene concentration to 40 mg/L has a positive effect on both the anthracene degradation rate and the power density by 79 and 83.93 %, respectively, which attained by the best inoculum AS+PP (degradation rate of 41 μM/d and a maximum power density of 287.04 mW/m2).This study highlights the possibility of using MFCs technology to generate renewable electricity and achieve high degradation rates of anthracene simultaneously, through co-metabolism.Int J Appl Sci Biotechnol, Vol 3(2): 151-161 DOI: http://dx.doi.org/10.3126/ijasbt.v3i2.12731

Microbial fuel cells (MFCs) have long been researched for their use as energy recovery devices during wastewater treatment. However, commercial applications of MFC systems have been challenged by high material costs and low energy recovery efficiencies. While energy densities remain low for these systems, recent work has demonstrated a reduction in capital costs, low biomass production, odor reduction, and accelerated treatment rates relative to conventional anaerobic systems. Here we describe a small pilot scale (100 gallon) anaerobic MFC system that is able to remove 88% of biological oxygen demand (BOD) and 80% of volatile suspended solids (VSS) from primary sludge in a 7 day residence time. A duplicate system was operated in parallel and held at open-circuit to determine what portion of BOD removal was associated with electrogenic activity as opposed to physical trapping or other mechanisms. The open-circuit system was only able to remove 45% of BOD and 38% of VSS in the same operational time frame. Under closed circuit conditions, operating with a 10 Ohm resistor, a maximum BOD removal rate of 1.09 kg-BOD/m3/day was achieved for primary sludge samples at ambient temperatures, while the open circuit condition showed a maximum BOD removal rate of 0.47 kg-BOD/m3/day. A coulombic efficiency of 13% was measured from the closed circuit system during maximum BOD removal. While system improvements are still required, these results represent significant progress toward the practical development of MFCs for municipal wastewater treatment and suggest that MFC technology may contribute toward realizing energy efficient water recycling.

A double-chamber microbial fuel cell (MFC) was used to dispose Dioscorea Zingiberensis wastewater and retrieve electrical energy. Both electrical performance and contaminant degradation characteristics were investigated. The potential of the MFC achieved 0.50-0.55 V over a 1000 ohm resistance, and the Coulombic efficiency was 7.01% or so. The maximum power density was about 350 mW/m2. During the operation cycle, COD was removed 82.6% and 10.9% in the anodic and cathodic chamber, respectively. In anodic chamber, simple acid, sugars and cellulose in wastewater were utilized while complicated organic matters including furanic and aromatic compounds were broken down by breaking side-chains and opening rings. In cathodic chamber, fatty ester and alkene were removed while aromatic compounds were degraded further. The results indicate that MFC provides a new approach for resource recovery treatment of Dioscorea Zingiberensis wastewater.

BackgroundThe target of this paper is to improve the performance of the microbial electrolysis cell (MEC). The performance of MEC including bio-hydrogen production and energy recovery is depending on the values of three controlling parameters including buffer concentration, dilution factor, and applied voltage.ProblemTherefore, defining the optimal values of three controlling parameters is the challenge of the work.MethodologyIn this paper the artificial gorilla troops optimization has been combined with and ANFIS modelling to increase the bio-hydrogen production from MEC. At first, using measured data, a model is created to simulate the MEC in terms of three controlling parameters. Then, for first time, an artificial gorilla troops optimization (AGTO) has been used to determine the optimal values of buffer concentration, dilution factor, and applied voltage to boost simultaneously bio-hydrogen production and energy recovery of MEC. To demonstrate the superiority of integration between ANFIS modelling and AGTO, the obtained results are compared with RSM methodology, and artificial neural network integrated with particle swarm optimization.FindingsFor hydrogen yield model, the RMSE lowered from 67.5 using RSM to 5.562 using ANFIS (decreased by 91.7%) as compared to RSM. The R-square for prediction rises from 0.94 (using RSM) to 0.99 (using ANFIS) by about 5.32%. For the ANFIS model of energy recovery, the RMSE decreased from 31.7 to 2.83 utilising ANFIS, a decrease of 91%. The R-square for prediction rises from 0.95 (using RSM) to 0.986 (using ANFIS) by about 3.8%. Compared with measured data, the integration between ANFIS and AGTO succeed to increase the hydrogen yield from 576.3 mL/g-VS to 843.32 mL/g-VS. in sum, the total performance of the MEC has been increased by 34.74%, 29.9% and 24.38% respectively compared to measured data, RSM and ANN-PSO.
