“…There are also sensors that determine the amount of VFAs, rather than their individual concentrations. Thus, in [ 199 ] it was proposed to use a complex biofilm based on the bacteria Geobacter , Hydrogenophaga , Pelobacter , Chryseobacterium , Oryzomicrobium , and Dysgonomonas to detect the total content of VFAs in samples. It was shown that the sensor had a linear response to concentrations from 3 to 14 mM, and the measurement time was from 2 to 5 h.…”

Microbial biofilms present one of the most widespread forms of life on Earth. The formation of microbial communities on various surfaces presents a major challenge in a variety of fields, including medicine, the food industry, shipping, etc. At the same time, this process can also be used for the benefit of humans—in bioremediation, wastewater treatment, and various biotechnological processes. The main direction of using electroactive microbial biofilms is their incorporation into the composition of biosensor and biofuel cells This review examines the fundamental knowledge acquired about the structure and formation of biofilms, the properties they have when used in bioelectrochemical devices, and the characteristics of the formation of these structures on different surfaces. Special attention is given to the potential of applying the latest advances in genetic engineering in order to improve the performance of microbial biofilm-based devices and to regulate the processes that take place within them. Finally, we highlight possible ways of dealing with the drawbacks of using biofilms in the creation of highly efficient biosensors and biofuel cells.

“…Three-chambered MFCs as shown in Figure 4 C, were designed to improve stability; however, they are highly costly [ 118 ]. Air cathodes have the same benefits as the three-chambered MFCs but have reduced operational costs [ 119 ]. Other AD effluents such as ammonium and fumarate have been demonstrated to influence the voltage output of MFC sensors [ 120 ].…”

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.

“…9 BESs can provide real-time amperometric sensory data of soluble carbon concentrations and metabolic activity, 10,11 and act as an early warning system for toxic shocks or overloading events. [12][13][14] BES sensing of soluble carbonaceous compounds has especially been used for volatile fatty acids (VFA) monitoring in anaerobic digestion (AD) units, as the failure of an AD process is often marked by an accumulation of VFA due to a disrupted symbiosis of fermentation reactions in the system. 15 BES-based VFA sensors developed under controlled environmental conditions have demonstrated a wide range of detection depending on their configurations.…”
