“…Wang, Hsieh, and Wang report on the use of MFCs with microbial consortia from wastewater which are capable of degrading large quantities of contaminants in anaerobic systems (6,20,21,22,23). The main advantage of these studies is the size of the reactors which are used as cells, achieving the creation of small, highly sensitive equipment.…”

“…However, the disadvantage of MFCs is the time taken in order to stabilise them, which can take months before beginning to measure the response of the BOD through biosensors inside the cell. These can be cathodic like electron acceptors in order to determine the dissolved oxygen or activated carbon cathodes (6,20). Depending on the microorganisms used, the bioavailability of the organic matter, and the robustness of the sensor, it is possible to obtain linear ranges which are sufficiently large to suggest the use of these electrodes as substitutes for traditional electrodes if and when a standardisation and validation process has been previously carried out (24,25).…”

Biochemical oxygen demand is a widely used technique in order to determine the organic material in water. However, it presents various negative points regarding its use, some of the most important being the time (5 days), as well as the response measurement through Dissolved Oxygen (DO); various authors have tried to increase the sensitivity and at the same time accelerate the response time through the production or modification of electrochemical sensors. This work shows a summary of the modifications that have been brought about in a period of time corresponding to the decade 2010-2020 with a view to presenting a condensed set of analysed information as a guide for future investigations. The most relevant investigations are produced through the modification of sensors and the use of microbial fuel cells using microorganisms, such as biosensitive agents, in order to give an electrochemical response and manage to determine the BOD.

“…The resulting sensor was able to detect low concentrations of BOD. The replacement of platinum with the highly catalytic manganese oxide showed an improvement in the detection limits of BOD and shorter response times [ 104 , 105 ]. Microbial attachment to the anode can also affect BOD detection.…”

Hydrogel materials have been used extensively in microbial electrochemical technology (MET) and sensor development due to their high biocompatibility and low toxicity. With an increasing demand for sensors across different sectors, it is crucial to understand the current state within the sectors of hydrogel METs and sensors. Surprisingly, a systematic review examining the application of hydrogel-based METs to sensor technologies has not yet been conducted. This review aimed to identify the current research progress surrounding the incorporation of hydrogels within METs and sensors development, with a specific focus on microbial fuel cells (MFCs) and microbial electrolysis cells (MECs). The manufacturing process/cost, operational performance, analysis accuracy and stability of typical hydrogel materials in METs and sensors were summarised and analysed. The current challenges facing the technology as well as potential direction for future research were also discussed. This review will substantially promote the understanding of hydrogel materials used in METs and benefit the development of electrochemical biosensors using hydrogel-based METs.

“…Among these factors, the cathodic electron acceptor has been found to be crucial to MFC performance. The traditional MFCs use dissolved oxygen as cathodic electron acceptor, but nowadays, compared with dissolved oxygen, redox mediators such as ferricyanide (Wei et al 2012), sodium bromate (Dai et al 2016), potassium dichromate (Sindhuja et al 2018), or potassium permanganate (Wang et al 2019;You et al 2006), as cathode electron acceptors of MFCs could improve the electricity production of MFCs. Most studies have shown that ferricyanide was excellent cathodic electron acceptor, and MFCs with potassium ferricyanide could avoid oxygen intrusion into the anolyte in comparison to those containing oxygen (Cai et al 2016), which could maintain anaerobic conditions (Logan et al 2019), and some exoelectrogenic microorganisms were strict anaerobes in the anodic chamber (Yilmazel et al 2018), so that ferricyanide could generate relatively a much higher power density than oxygen.…”

A two-chamber slurry microbial fuel cell (SMFC) was constructed using black-odorous river sediments as substrate for the anode. We tested addition of potassium ferricyanide (K 3 [Fe(CN) 6 ]) or sodium chloride (NaCl) to the cathode chamber (0, 50, 100, 150, and 200 mM) and aeration of the cathode chamber (0, 2, 4, 6, and 8 h per day) to assess their response on electrical generation, internal resistance, and methane emission over a 600-h period. When the aeration time in the cathode chamber was 6 h and K 3 [Fe(CN) 6 ] or NaCl concentrations were 200 mM, the highest power densities were 6.00, 6.45, and 6.64 mW•m −2 , respectively. With increasing K 3 [Fe(CN) 6 ] or NaCl concentration in the cathode chamber, methane emission progressively decreased (mean ± SD: 181.6 ± 10.9 → 75.5 ± 9.8 mg/m 3 •h and 428.0 ± 28.5 → 157.0 ± 35.7 mg/m 3 •h), respectively, but was higher than the reference having no cathode/anode electrodes (~ 30 mg/m 3 •h). Cathode aeration (0 → 8 h/day) demonstrated a reduction in methane emission from the anode chamber for only the 6-h treatment (mean: 349.6 ± 37.4 versus 299.4 ± 34.7 mg/m 3 •h for 6 h/day treatment); methane emission from the reference was much lower (85.3 ± 26.1 mg/m 3 •h). Our results demonstrate that adding an electron acceptor (K 3 [Fe(CN) 6 ]), electrolyte solution (NaCl), and aeration to the cathode chamber can appreciably improve electrical generation efficiency from the MFC. Notably, electrical generation stimulates methane emission, but methane emission decreases at higher power densities.
