“…In both chambers, the suspension of DvH JWT700 had a larger oxidation current density than DvH JW3422 and DvH JWT716, suggesting DvH JWT716 secreted more stable and oxidative compounds than the other two. These compounds might be quinone initiated or benzene derivatives chemicals or due to the similar CV curves presented in a previous study (59). In DvH, flavin adenine dinucleotide (FAD) in quinone form which is the electron shuttle could accept two electrons and two protons to become hydroquinone form (FADH 2 ) (60).…”

Extracellular electron transfer (EET) propels microbial fuel cell (MFC) technology and contributes to the mobility of redox active minerals and microbial syntrophy in nature. Although extensive studies on Sulfate-reducing bacteria (SRB)-mediated metal electrode corrosion have been done, there remain knowledge gaps on SRB EET to electrodes. Our MFCs with Desulfovibrio vulgaris Hildenborough (DvH), a model SRB, indicated that DvH can harvest and send electrons to the carbon cloth electrode. Patterns in current production compared to variations of electron donor/acceptor ratios in the anode and cathode suggested that attachment of DvH to the electrode and biofilm density were critical for effective electricity generation. Analysis of DvH biofilms at different conditions by electron microscopy indicated DvH utilized filaments that resemble nano-pili to attach on electrodes and facilitate EET from cell-to-cell and to the electrode. Proteomics profiling of electroactive respiration proteins indicated DvH adapted to electroactive respiration by presenting more pili-, flagellar- related proteins and histidine kinases on electrodes. The mutant with a deletion of the major pilus-producing gene yielded less voltage and far less attachment to the electrode, suggesting the importance of pili in EET. The mutant with a deficiency in biofilm formation, however, did not eliminate current production indicating the existence of indirect EET. Untargeted metabolomics profiling showed flavin-based metabolites, potential electron shuttles, were dysregulated between respiration modes. This work revealed the metabolic flexibility of DvH to thrive in non-ideal conditions with solid surfaces as both an electron acceptor and donor by using a combination of direct and indirect EET mechanisms.

Micro‐supercapacitors emerge as an important electrical energy storage technology expected to play a critical role in the large‐scale deployment of autonomous microdevices for health, sensing, monitoring, and other IoT applications. Electrochemical double‐layer capacitive storage requires a combination of high surface area and high electronic conductivity, with these being attained only in porous or nanostructured carbons, and recently found also in conducting metal–organic frameworks (MOFs). However, techniques for conformal deposition at micro‐ and nanoscale of these materials are complex, costly, and hard to upscale. Herein, the study reports direct, one step non‐sacrificial anodic electrochemical deposition of Ni3(2,3,6,7,10,11‐hexaiminotriphenylene)2 – Ni3(HITP)2, a porous and electrically conducting MOF. Employing this strategy enables the growth of Ni3(HITP)2 films on a variety of 2D substrates as well as on 3D nanostructured substrates to form Ni3(HITP)2 nanotubes and Pt@ Ni3(HITP)2 core–shell nanowires. Based on the optimal electrodeposition protocols, Ni3(HITP)2 films interdigitated micro‐supercapacitors are fabricated and tested as a proof of concept.
