“…an organic compound itself) are interconnected through electron transfer mechanisms (Cavalcante et al, 2017). Although pure cultures were initially employed and largely investigated, it was later demonstrated that open cultures are advantageous due to their robust and resilient communities, and their increased production rates owing to their synergistic behaviour (Pinto et al, 2021;Paquete et al, 2022). This brings the technology closer to environmental conditions and its utilization has been proven to be both, cost and energy more efficient (Pinto et al, 2021).…”

“…Similar findings have been reported in numerous other studies (Table ). However, so far, research has been focused on interactions between exoelectrogens . Therefore, we argue that a better understanding of the total microbial community structure and the microbial interactions associated with nonexoelectrogens as well as what properties are community-intrinsic is necessary for further improvement of MESs.…”

Microbial electrochemical systems have gained much attention over the past decade due to their potential for various environmental engineering applications ranging from energy production to wastewater treatment to bioproduction. At the heart of these systems lie exoelectrogens−microorganisms capable of exporting electrons generated during metabolism to external electron acceptors such as electrodes. The bacterial biofilm communities on these electrodes are dominated by exoelectrogens but are nonetheless extremely diverse. So far, within the field, the main focus has been on the electroactive bacteria. However, to broaden our understanding of these communities, it is crucial to clarify how the remaining inhabitants of electrode-respiring biofilms contribute to the overall function of the biofilm. Ultimately, such insights may enable improvement of microbial electrochemical systems by reshaping the community structure with naturally occurring beneficial strains.

“…Herein, it is necessary to accomplish that the microbial cells inside biofilm do not utilize only one type of electron transfer, but their different combinations. The whole system is more complicated than it may seem at first glance, because of the additional ability of microbial cells to communicate with each other via diffusible intermediates, direct electron exchange between physically connected cells, and conductive particles [173].…”

This review deals with microbial adhesion to metal-based surfaces and the subsequent biofilm formation, showing that both processes are a serious problem in the food industry, where pathogenic microorganisms released from the biofilm structure may pollute food and related material during their production. Biofilm exhibits an increased resistance toward sanitizers and disinfectants, which complicates the removal or inactivation of microorganisms in these products. In the existing traditional techniques and modern approaches for clean-in-place, electrochemical biofilm control offers promising technology, where surface properties or the reactions taking place on the surface are controlled to delay or prevent cell attachment or to remove microbial cells from the surface. In this overview, biofilm characterization, the classification of bacteria-forming biofilms, the influence of environmental conditions for bacterial attachment to material surfaces, and the evaluation of the role of biofilm morphology are described in detail. Health aspects, biofilm control methods in the food industry, and conventional approaches to biofilm removal are included as well, in order to consider the possibilities and limitations of various electrochemical approaches to biofilm control with respect to potential applications in the food industry.
