“…Similarly, these conclusions may be modified when considering yeast-based anodes. Several yeast species have shown interesting capacities to form bioanodes (Hubenova and Mitov, 2015), including with 3-dimensonal porous electrodes (Hubenova et al, 2011;Christwardana et al, 2019), but the fact that there are larger than bacterial cells and the possible differences in biofilm characteristics may lead to different behaviour from that observed with bacterial cells. A specific critical review of the literature would be useful in this field.…”

Microbial anodes are the cornerstone of most electro-microbial processes. Designing 3-dimensional porous electrodes to increase the surface area of the electroactive biofilm they support is a key challenge in order to boost their performance. In this context, the critical review presented here aims to assess whether an optimal range of pore size may exist for the design of microbial anodes. Pore sizes of a few micrometres can enable microbial cells to penetrate but in conditions that do not favour efficient development of electroactive biofilms. Pores of a few tens of micrometres are subject to clogging. Sizes of a few hundreds of micrometres allow penetration of the biofilm inside the structure, but its development is limited by internal acidification. Consequently, pore sizes of a millimetre or so appear to be the most suitable. In addition, a simple theoretical approach is described to establish basis for porous microbial anode design.

“…In the work of Christwardana et al [ 57 ], the quorum-sensing molecules, which are employed by microorganisms as a major means of communication and biofilm formation [ 58 ] were used for MFC anode functionalization to ascertain the suitable surface for microbial attachment, to enhance the biofilm formation, activity, and conductivity for the electron transfer and electron–electrode interaction in MFCs [ 59 ]. This scheme of the anode functionalization proved to be rather efficient, as the maximum power density of the MFC were 159.46 ± 10.68 mW m −2 and 156.57 ± 5.84 mW m −2 , using different quorum sensing molecules phenylethanol and tryptophol, respectively.…”

“…The different strategy was developed by de Oliveira et al [ 14 ], which enabled to achieve more stable membrane. Biomaterials such as algae [ 52 ] and quantum sensing molecules [ 57 ] were employed for better microorganism entrapment to the electrode surface, and in the alginate case the extraordinary stability for 44 days was achieved most likely owing to biocompatible environment provided by algae preventing the cells from leakage to the buffer.…”

“…MFCs based on classes of Gammaproteobacteria and Negativicutes were applied for bioremediation and energy generation from sludge [ 56 ]. In many cases the main focus of the researches were on the electrode surface modifications with various materials as the guide for better strategy in order to develop the devices with better performance [ 7 , 14 , 43 , 44 , 49 , 51 , 57 ] rather than a MFC ready for applications. In many of the aforementioned cases S. Cerevisiae was used as a model microorganism.…”

This review focuses on the overview of microbial amperometric biosensors and microbial biofuel cells (MFC) and shows how very similar principles are applied for the design of both types of these bioelectronics-based devices. Most microorganism-based amperometric biosensors show poor specificity, but this drawback can be exploited in the design of microbial biofuel cells because this enables them to consume wider range of chemical fuels. The efficiency of the charge transfer is among the most challenging and critical issues during the development of any kind of biofuel cell. In most cases, particular redox mediators and nanomaterials are applied for the facilitation of charge transfer from applied biomaterials towards biofuel cell electrodes. Some improvements in charge transfer efficiency can be achieved by the application of conducting polymers (CPs), which can be used for the immobilization of enzymes and in some particular cases even for the facilitation of charge transfer. In this review, charge transfer pathways and mechanisms, which are suitable for the design of biosensors and in biofuel cells, are discussed. Modification methods of the cell-wall/membrane by conducting polymers in order to enhance charge transfer efficiency of microorganisms, which can be potentially applied in the design of microbial biofuel cells, are outlined. The biocompatibility-related aspects of conducting polymers with microorganisms are summarized.

“…Differently from EFCs, in MFCs, the biotic component is represented not by a single active and complex protein (i.e., an enzyme) but by a whole-cell, with its cellular membrane, cytoplasm, and organelles representing a living microorganism, usually organized into a social community known as biofilm [228]. The peculiar selectivity and specificity of EFCs are, thus, lost because the living cells of the MFC's biofilm have a plethora of different enzymes to perform metabolic and catabolic complex bioreaction cycles, and not just a single and direct reaction.…”

Next-generation wearable technology needs portable flexible energy storage, conversion, and biosensor devices that can be worn on soft and curved surfaces. The conformal integration of these devices requires the use of soft, flexible, light materials, and substrates with similar mechanical properties as well as high performances. In this review, we have collected and discussed the remarkable research contributions of recent years, focusing the attention on the development and arrangement of soft and flexible materials (electrodes, electrolytes, substrates) that allowed traditional power sources and sensors to become viable and compatible with wearable electronics, preserving or improving their conventional performances.
