“…High acetate concentrations can inhibit the abundance of Acetobacterium over time. Thus, several separation methods, such as ion-exchange resin (Bajracharya et al 2017) and liquid membrane extraction (Batlle-Vilanova et al 2017), should be applied to improve the acetate production rate in the reaction.…”

“…Since Nevin et al (2010) first demonstrated the proofof-concept of MES, many crucial elements, such as electrode materials (Bajracharya et al 2015;Jourdin et al 2015;Marshall et al 2013;Song et al 2018), reactor designs (Giddings et al 2015), membranes (Gildemyn et al 2017;Xiang et al 2017), microbial communities (Nevin et al 2011;Patil et al 2015;Modestra and Mohan 2017), and product separation (Bajracharya et al 2017;Batlle-Vilanova et al 2017;Gildemyn et al 2015), have been studied in MES. In comparison with pure strains Nevin et al 2010;Zhang et al 2013), mixed culture (Dong et al 2018;Marshall et al 2013;Modestra and Mohan 2017;Jourdin et al 2014;Patil et al 2015;Song et al 2017Song et al , 2018 is possibly more suitable for the commercialization of MES because it has better resistance to environmental disturbances, high biomass, and acetate production rate (Marshall et al 2013).…”

Microbial electrosynthesis (MES) is potentially useful for the biological conversion of carbon dioxide into value-added chemicals and biofuels. The study evaluated several limiting factors that affect MES performance. Among all these factors, the optimization of the applied cell voltage, electrode spacing, and trace elements in catholytes may significantly improve the MES performance. MES was operated under the optimal condition with an applied cell voltage of 3 V, an electrode spacing of 8 cm, 2× salt solution, and 8× trace element of catholyte for 100 days, and the maximum acetate concentration reached 7.8 g L −1 . The microbial community analyses of the cathode chamber over time showed that Acetobacterium, Enterobacteriaceae, Arcobacter, Sulfurospirillum, and Thioclava were the predominant genera during the entire MES process. The abundance of Acetobacterium first increased and then decreased, which was consistent with that of acetate production. These results provided useful hints for replacing the potentiostatic control of the cathodes in the future construction and operation of MES. Such results might also contribute to the practical operation of MES in large-scale systems. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

“…For practical implementation, the generation of molecules with higher value than acetate, such as longer carbon-chain organic compounds and alcohols, is desirable. Approaches with mixedculture MES that exploit intermediate metabolite transfer and microbial cooperation show some success to extend the product spectrum to n-butyrate, propionate, ethanol, isopropanol and caproate (Ganigué et al, 2015;Arends et al, 2017;Batlle-Vilanova et al, 2017;Jourdin et al, 2018). In addition, the low rate EEU of electroautotrophic acetogens and methanogens still constitute a big limit for application on a commercial scale.…”

Electroautotrophs are microbes able to perform different biocathodic reactions by using CO 2 as sole carbon source and electrochemical reducing power as a sole energy source. Electroautotrophy has been discovered in several groups of microorganisms, including iron-oxidizing bacteria, iron-reducing bacteria, nitrate-reducing bacteria, acetogens, methanogens and sulfate-reducing bacteria. The high diversity of electroautrophs results in a wide range of Bioelectrochemical Systems (BES) applications, ranging from bioproduction to bioremediation. In the last decade, particular research attention has been devoted toward the discovery, characterization and application of acetogenic and methanogenic electroautotrophs. Less attention has been given to autotrophic sulfate-reducing microorganisms, which are extremely interesting biocatalysts for multiple BES technologies, with concomitant CO 2 fixation. They can accomplish water sulfate removal, hydrogen production and, in some case, even biochemicals production. This mini-review gives a journey into electroautotrophic ability of sulfate-reducing bacteria and highlights their possible importance for biosustainable applications. More specifically, general metabolic features of autotrophic sulfate reducers are introduced. Recently discovered strains able to perform extracellular electron uptake and possible molecular mechanisms behind this electron transfer capacity are explored. Finally, BES technologies based on sulfate-reducing electroautotrophs are illustrated.

“…With the use of CO 2 and clean water, MESs are capable of converting agricultural and forestry residues (e.g., corn stalk, stover, wood, grass, leaves, immature cereal, etc.) into syngas [29], H 2 [96], CH 4 [97], formic acid [98], ethylene [24], methanol [99], dimethyl ether [100], urea [7], succinic acid [101], etc. Through mineralization reactions, CO 2 can also be synthesized into precursors of polymers and carbonates for construction applications [102].…”

Background: Bioelectrochemical systems (BESs) are emerging energy-effective and environment-friendly technologies. Different applications of BESs are able to effectively minimize wastes and treat wastewater while simultaneously recovering electricity, biohydrogen and other value-added chemicals via specific redox reactions. Although there are many studies that have greatly advanced the performance of BESs over the last decade, research and reviews on agriculture-relevant applications of BESs are very limited. Considering the increasing demand for food, energy and water due to human population expansion, novel technologies are urgently needed to promote productivity and sustainability in agriculture. Methodology: This review study is based on an extensive literature search regarding agriculture-related BES studies mainly in the last decades (i.e., 2009–2018). The databases used in this review study include Scopus, Google Scholar and Web of Science. The current and future applications of bioelectrochemical technologies in agriculture have been discussed. Findings/Conclusions: BESs have the potential to recover considerable amounts of electric power and energy chemicals from agricultural wastes and wastewater. The recovered energy can be used to reduce the energy input into agricultural systems. Other resources and value-added chemicals such as biofuels, plant nutrients and irrigation water can also be produced in BESs. In addition, BESs may replace unsustainable batteries to power remote sensors or be designed as biosensors for agricultural monitoring. The possible applications to produce food without sunlight and remediate contaminated soils using BESs have also been discussed. At the same time, agricultural wastes can also be processed into construction materials or biochar electrodes/electrocatalysts for reducing the high costs of current BESs. Future studies should evaluate the long-term performance and stability of on-farm BES applications.
