The purpose of this study is to improve the performance of solid phase microbial fuel cells (SMFC) by pretreating straw with several reagents (H2SO4, NaOH and H2O2). Electrochemical performance and straw properties were measured. The results show that when compared with the control group (untreated rice straw), the SMFC with rice straw after hydrogen peroxide pretreatment (SMFC-H2O2) and the SMFC with rice straw after sulfuric acid pretreatment (SMFC-H2SO4) lasted more than 6 to 8 days under high voltage (higher than 500 mV). Furthermore, an SMFC with rice straw after sodium hydroxide pretreatment (SMFC-NaOH) can last more than 22 days under high voltage, which is almost twice the endurance of the control group. The maximum power density of the SMFC-NaOH was 140 mW/m2 on day 50, which was 3.6 times that of the control. Therefore the NaOH pretreatment worked in favor of rice straw biodegradation by anaerobic microorganisms and extended the sustained discharge time of the SMFC.

A novel anode modified by 1,5-dihydroxyanthraquinone/multiwalled carbon nanotubes (DAQ/MWCNTs) composite was fabricated in order to improve its electrochemical performance in marine sediment microbial fuel cell (MSMFC). The number of microbes on the DAQ/MWCNTs modified anode is 18.02 times of blank anode, and it has the best electrochemical performance compared with other anodes. Its exchange current density and biofilm capacitance are 1472.15 times and 18.66 times higher than that of blank anode, respectively. The maximum power density of composite modified MSMFC (890.12 mW·m−2) is 3.01-fold of blank cell (296.11 mW·m−2). The mechanism analysis of DAQ/MWCNTs shows that DAQ, as an electron-transfer mediator, can accelerate electron transfer to benefit the electrochemical performance of anode. This provides a new anode modification method for the development of high power MSMFC as long-term power source to drive monitoring instruments.

Non-availability of good quality water in sufficient quantities and the environmental impacts of used water discharges have led to the treatment and reuse of the aquaculture water contaminated with dissolved organics and ammonia rather than discharging it.This paper explores the effectiveness of in-situ sediment microbial fuel cell (MFC) for aquaculture water treatment along with generation of electricity.A sediment microbial fuel cell (SMFC) was designed and the efficiency of stainless steel mesh as well as graphite plate electrodes have been looked into.The graphite plate SMFC gave higher COD, TKN and TN removal efficiency (79 ± 1%; 94 ± 3%; 62 ± 4%, respectively) than stainless steel SMFC (69 ± 3%; 74 ± 4%; 30 ± 3%, respectively).This SMFC demonstrated successful treatment of aquaculture water offering the advantage of in situ remediation of aquaculture pond water.This system will have the potential to drastically reduce the cost of treatment apart from savings in the pumping cost, which is inevitable when the aquaculture water is treated externally and reused.As expected, these SMFCs generated very low power that can be used for powering the sensors and demonstrated successful in-situ remediation of aquaculture water.

This study used polyvinyl alcohol (PVA) as the proton exchange membrane (PEM) of sediment microbial fuel cells (SMFCs) to assess the oxygen diffusion and proton transfer performance of two types of PEMs, i.e. PVA elastomer (PVA-E) and PVA hydrogel (PVA-H). The oxygen diffusion coefficient of the PVA-E (0.42 × 10−4 cm 2/s) was 36.7% of that of the PVA-H. By reducing the amount of oxygen diffused from the cathode to the anode, a favorable water absorption rate (74.7%), 2.10–3.55 times of those obtained in previous studies, was achieved, enabling the rate of proton transfer by the PVA-E to reach 200.7 μM H+/s/m. The Cu2+ removal efficiency of the SMFCs with oxygen separation membranes was 1.21 times that of the SMFCs without oxygen separation membranes. With high external resistance, the SMFCs generated low currents under high voltage output, which was conducive to Cu2+ migration. This explains the voltage output peak (168.0 mV) under an external resistance of 1000 Ω. Furthermore, under the same external resistance, the Cu2+ removal (55.1%) was 1.14–1.38 times that of the corresponding rates achieved under external resistances of 20 and 510 Ω, respectively. X-ray diffraction revealed that electrocoagulation constituted the main mechanism of Cu2+ removal from sediment with SMFCs. Integrating PVA-E and SMFC can facilitate the fabrication of a device with high power output and potential for use in removing Cu2+ from sediment.

The effect of stirring rates in anodic area of sediment microbial fuel cell on its operating performance, in terms of variations in power generation and sludge properties, was investigated in this work. The power density under 100 r/min stirring rate amounted to the highest peak value (98.8 mW/m2 for the 9th cycle). The volume average sizes of sludge flocs decreased with increasing the stirring rates, but the content of extracellular polymeric substances of sludge increased. According to cyclic voltammetry examination, significant improvement in electrochemical activity with microorganism growth was due to some kinds of mediating compounds produced in cell-associated form.

Applying sediment microbial fuel cells (SMFCs) into sediment can remediate the sediment; however, nutrient salts cannot be removed by SMFCs effectively. In this study, sediment mixed with steel-making slag is used a fuel in SMFCs for understanding the potential of steel-making slag in nutrient salt removal in SMFCs. To the best of our knowledge, no report related to the use of steel-making slag in SMFCs is found in the literature. The combination of SMFCs with steel-making slag is expected to make the individual efficiency of SMFCs and steel-making slag more reactive, and is another way to increase the benefit of using steel-making slag. Experimental results showed that steel-making slag was more effective for adsorbing nutrient salts in SMFCs. Interestingly, the combination of SMFCs with steel-making slag can increase the individual efficiency of SMFCs and steel-making slag.

The industrial contamination of marine sediments with chromium, copper and nickel in Penang, Malaysia was addressed with bio-remediation, coupled with power generation, using in situ sediment microbial cells (SMFCs) under various conditions. The efficiency of aerated sediment microbial fuel cells (A-SMFCs) and non-aerated sediment microbial fuel cells (NA-SMFCs) was studied. The A-SMFCs generated a voltage of 580.5 mV between 50 and 60 days, while NA-SMFCs produced a voltage of 510 mV between 60 and 80 days. The cell design point for A-SMFCs was 2 kΩ, while for NA-SMFCs it was 200 Ω. In both SMFCs, the maximum current values relating to forward scanning, reverse scanning and oxidation/reduction peaks were recorded on the 80 th day. The anode showed maximum additional capacitance on the 80 th day (A-SMFC: 2.7 F cm -2 ; and NA-SMFC: 2.2 F cm -2 ). The whole cell electrochemical impedance using the Nyquist model was 21 Ω for A-SMFCs and 15 Ω for NA-SMFCs. After glucose enrichment, the impedance of A-SMFCs was 24.3 Ω and 14.6 Ω for NA-SMFCs. After 60 days, the A-SMFCs reduced the maximum amount of Cr(vi) to Cr(iii) ions (80.70%) and Cu(ii) to Cu(i) ions (72.72%), and showed maximum intracellular uptake of Ni(ii) ions (80.37%); the optimum remediation efficiency of NA-SMFCs was after 80 days toward Cr(vi) ions (67.36%), Cu(ii) ions (59.36%) and Ni(ii) ions (52.74%). Both SMFCs showed highest heavy metal reduction and power generation at a pH of 7.0. SEM images and 16S rRNA gene analysis showed a diverse bacterial community in both A-SMFCs and NA-SMFCs. The performance of A-SMFCs showed that they could be exercised as durable and efficient technology for power production and the detoxification of heavy metal sediments. The NA-SMFCs could also be employed where anaerobic fermentation is required.

Sediment microbial fuel cells (SMFCs) have been used for treating pollutants in sediment or overlying water. This study investigated the feasibility of constructing SMFCs under aquaculture conditions by employing indigenous carbohydrates as substrates to enhance the removal efficiency of polycyclic aromatic hydrocarbons (PAHs) in sediment, as well as the correlation between PAHs removal and electricity generation in SMFCs. The results showed that adding glucose could allow SMFCs to generate more electrical power and increase the removal efficiency of PAHs (by 57.2% for naphthalene, 41.3% for acenaphthene, and 36.5% for pyrene). In addition, starch enhanced PAHs removal by 49.9%, 35.8%, and 31.2%, respectively, whereas cellulose enhanced removal by 44.3%, 29.3%, and 26.9%, respectively. Pearson correlation coefficients between the level of electrical power generated and the removal masses of the three PAHs were 0.485, 0.830**, and 0.851**. Thus, the use of SMFCs could be an effective approach for PAH treatment in aquaculture, and the electrical power generated could be used as an in-situ indicator for the biodegradation rate of SMFCs.

Eutrophication is one of the major ecological problems of our era. It accelerates the growth of aquatic plant and algae, eventually leading to ecological deterioration. Based on a 700-day lab experiment, this paper investigated the contrasting effects of sediment microbial fuel cells (SMFCs) on the removal of macrophyte litter in a macrophyte-dominated area and an algae-dominated area from two bay areas of a shallow eutrophic lake. The results revealed that the removal efficiencies of total organic carbon increased by 14.4% in the macrophyte-dominated area and 7.8% in the algae-dominated area. Moreover, it was found that sediment samples from the macrophyte-dominated area became more humified and had a higher electricity generation compared to the sediment samples from the algae-dominated area. Pyrosequencing analysis further determined that SMFC promoted more aromatic compound-degrading bacteria growth in sediments from the macrophyte-dominated area than from the algae-dominated area. Our study demonstrated that SMFC could enhance organic matter degradation, especially plant litter degradation, but this influence showed different from sediment sources. Thus, SMFC is capable of providing a useful strategy for delaying the terrestrialization of lakes areas suffering from eutrophication.

The anode is considered to be a key factor to improve the single-chamber bioelectrochemical system's efficiency to degrade oily sludge in sediment while generating electricity. There are few studies on the effect of the anode structure on the performance of oily sludge MFCs systematically. In this paper, an oily sludge bioelectrical system was constructed using carbon felt and carbon plate as anode materials, adjusting the anode material arrangement as transverse and longitudinal, and using different anode materials from single to sextuple anodes. The results of this study showed that the rate of degradation of oily sludge was greater with carbon felt (17.04%) than with the carbon plate (13.11%), with transverse (23.61%) than with the longitudinal (19.82%) arrangement of anodes, and with sextuple anodes (33.72%) than with a single anode (25.26%) in the sediment microbial fuel cells (SMFCs). A similar trend was observed when the voltage, power density, and electromotive force (EMF) of SMFCs were estimated between the carbon felt and carbon plate, transverse and longitudinal arrangements, single and sextuple anodes. It is concluded that the proper adjustment of anode arrangements, using carbon felt as an anode material, and increasing the number of anodes to six may accelerate the rate of degradation of oily sludge in oily sludge sediment microbial fuel cells (SMFCs). Furthermore, the electricity generation performance was also improved.

A simple, environmental friendly and biologically important sediment interfaced fuel cell was developed for the green energy generation. The soil sediment used for the study is enriched of rich anthropogenic free organic carbon, sufficient manganese and high level potassium contents as evidenced from the geochemical characterizations. The saccharides produced by the catalytic reaction of substrate chitosan were utilized for the growth of microorganisms and electron shuttling processes. Chitosan substrate influenced sediment microbial fuel cells exhibited the nearly two fold power increment over the substrate free fuel cells. The fuel cell efficiencies were further increased by bringing the substrate chitosan at nanometric level, which is nearly three and two fold higher than that of substrate free and chitosan influenced sediment microbial fuel cells, respectively, and the influential parameters involved in the power and longevity issues were addressed with different perspectives.

Abstract To online and in situ monitor the heavy metal shock in water, a novel sediment microbial fuel cell based sensor was developed with anode being inserted into flooded soil and cathode submerged in overlaying water. Immediately after CuSO 4 solutions were added into the overlaying water, the voltage signal generated by the sensor reached a peak and the increment from baseline voltage to peak voltage increased linearly with Cu 2+ concentrations up to 160 mg L −1 . After Cu 2+ shock, charge transfer resistance ( R ct ) of anode and cathode was determined by using electrochemical impedance spectroscopy. Soil DNA and RNA was extracted and 16S rRNA and 16S rRNA gene of dominant exoelectrogenic bacteria ( Geobacter and Clostridium ) was quantified. Result showed that Cu 2+ shock decreased cathodic charge transfer resistance ( R ct ) but did not affect anodic R ct . The addition of 320 mg L −1 Cu 2+ significantly reduced abundance and activity of Geobacter and Clostridium in surface soil (0–3 cm in depth) but had no effect on exoelectrogenic bacteria in deeper soil. Moreover, baseline voltage was stable after Cu 2+ shock. The result indicates that the sensor could online and in situ monitor Cu 2+ shock which increased voltage signal by promoting cathodic reaction without dramatically inhibiting exoelectrogenic bacteria.

Sediment microbial fuel cells (SMFCs) can covert the biomass and organic matters in sediments into electricity. SMFC stack is an essential way for the application of SMFCs. The unit distance and number will be crucial for SMFC stacks applied in practical environments. This study showed that the power density of individual SMFC increased with the unit distance when compared with SMFCs with a small distance. For hydraulically connected serial stacks, increasing unit distance from 2 to 28 cm decreased the potential loss from 50.4% to 11.3%, but the power output did not increase with either unit distance or number of units due to higher internal resistance and electrode reversal. For hydraulically connected parallel stacks, increasing unit number from one to three multiplied the power output but no further power increase was observed with four and five units, indicating an optimal unit number (OUN) in parallel stacks due to ion conduction. Similar performance was shown when using SMFC stacks to power a light-emitting diode and an environmental sensor. The results provide important information for improving the power and cost-effectiveness of SMFC stacks.
