“…Acylase, a degrading enzyme of AHL, is generally used to inhibit QS. However, Pan et al [113] also found that the addition of acylase can reduce the detection linearity and toxicity shock resistance of the single-chamber heavy-metal toxicity sensor MFC, which contradicts the research results of Chung et al [114]. Therefore, further research is needed to clarify the effectiveness of acylase on biosensors.…”

“…Pan et al [113] found that adding two types of AHLs (C6-HSL and 3OC12-HSL) to a single-chamber heavy-metal toxicity sensor MFC significantly increased the ratio of active cells and Geobacter in the anode mixed electrode biofilms, thus expanding the linear sensing range of MFC for Pb 2+ and enhancing the ability of electrode biofilms to recover electricity after being subjected to high concentrations of Cu 2+ toxicity. Chung et al [114] added acylase (5 µg/L), which led to a Very low detection limit of naphthenic acid and a quantitative determination of naphthenic acid concentration (9.4-94 mg/L). Compared to the control group, the sensitivity of the biosensor and the electrical signal output increased by 40% and ~70%, respectively.…”

Bioelectrochemical systems (BESs) are an emerging technology for wastewater treatment and resource recovery. These systems facilitate electron transfer between microorganisms and electrodes, enabling their application in various fields, such as electricity production, bioremediation, biosensors, and biocatalysis. However, electrode biofilms, which play a critical role in BESs, face several challenges (e.g., a long acclimation period, low attached biomass, high electron transfer resistance, and poor tolerance and stability) that limit the development of this technology. Quorum sensing (QS) is a communication method among microorganisms that can enhance the performance of BESs by regulating electrode biofilms. QS regulation can positively impact electrode biofilms by enhancing extracellular electron transfer (EET), biofilm formation, cellular activity, the secretion of extracellular polymeric substances (EPS), and the construction of microbial community. In this paper, the characteristics of anode electrogenic biofilms and cathode electrotrophic biofilms in BESs, EET mechanisms, and the main factors affecting biofilm formation were summarized. Additionally, QS regulation mechanisms for biofilm formation, strategies for enhancing and inhibiting QS, and the application of QS regulation for electrode biofilms in BESs were systematically reviewed and discussed. This paper provides valuable background information and insights for future research and development of BES platforms based on QS regulation of electrode biofilms.

“…It has also been demonstrated that it is possible to enhance the sensing of quorum by using acylase in an anode biofilm to improve the determination of naphthenic acid concentrations in a biosensor based on a microbial electrochemical cell. The addition of acylase increased the relative expression of QS-associated genes ( las R, las I, rhl R, rhl I, las A, and Lux R) by 7–100%, along with an increase in the number of known electroactive bacterial genera such as Geobacter (from 42% to 47%) and Desulfovibrio (from 6% to 11%) [ 111 ].…”

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.
