“…Microorganisms are entrapped on columns [35] or immobilized on membranes [36][37][38][39][40][41][42][43]. The microorganisms used are pure strains with or without enzymes [36][37][38][39], consortia of mixed strains , or inocula from wastewater-treatment plant (WWTPs) [39,40], synthetic wastewater [41], brackish waters [43] or standardized microbial cultures [42]. Inocula metabolize a broader spectrum of substrates but present a less stable composition and are consequently less constant over time.…”

“…Inocula metabolize a broader spectrum of substrates but present a less stable composition and are consequently less constant over time. Furthermore, while dynamic measurements offer a quicker response and a broader detection area, steady-state measurements give reliable results in the concentration range 15-50 mgO 2 /L [40]. BOM can also be monitored in anaerobic processes [44].…”

This critical review spans the past two decades and outlines sensors developed for measuring total (TOM) and biodegradable organic matter (BOM) in water. We report the state of the art of the most significant technologies. Although the focus is on in situ devices, we also mention on-line techniques able to lead to sensors sensu stricto and discuss them as possible emerging technologies. We divide the review into sections: (1) TOM; and (2) BOM. We first briefly outline each technique then analyze the published literature. We conclude with recommendations on the technological choices geared to specific research topics.

“…However, it is hard to be put into pilot scale or practice because of its limitation in volume size, which greatly hinder the development of MFCs in heavy metal treatment and power generation. So researchers explore the potentials of MFCs as a biosensors [6][7][8][9][10][11][12], which do not require a physical or chemical converter and has the characteristics of biosensors, also is easier to achieve the formation as an on-line monitoring biosensor [13][14][15].…”

In this study, a single chamber microbial fuel cell (MFC) was developed for heavy metal (copper ions) sensor with different concentrations at cathode, and its electrochemical activities in batch-mode operation including polarization curve, power density, anode potential, cathode potential and 30 minutes real-time voltage were characterized and studied. Under the condition of 1000 Ω external resistance, 100 mM PBS buffer and 1000 mg/L COD, results indicated that the real-time voltage of 30 min collected by the data acquisition was linearly developed with the change of concentration gradient, and the polarization curve showed that copper ion concentration and power density reflect a trend of X squared. In addition, the anode and cathode potential collected by the multimeter, also showed a trend of X 2. By studying the relationship between electrochemical parameters and heavy metal ion concentration, a reliable correlation could be established to help us to use the detected electrochemical parameters to estimate the concentration of heavy metal ions in the environment of sewage pollution, so as to provide theoretical support for the development of new heavy metal sensors. The results provided new ideas for the practical application of microbial fuel cells.
