Issue Date: | 2020 | Publisher: | WILEY-V C H VERLAG GMBH | Source: | Advanced Biosystems, 4(7) , (Art N° 2000006) | Abstract: | Cable bacteria are an emerging class of electroactive organisms that sustain unprecedented long-range electron transport across centimeter-scale distances. The local pathways of the electrical currents in these filamentous microorganisms remain unresolved. Here, the electrical circuitry in a single cable bacterium is visualized with nanoscopic resolution using conductive atomic force microscopy. Combined with perturbation experiments, it is demonstrated that electrical currents are conveyed through a parallel network of conductive fibers embedded in the cell envelope, which are electrically interconnected between adjacent cells. This structural organization provides a fail-safe electrical network for long-distance electron transport in these filamentous microorganisms. The observed electrical circuit architecture is unique in biology and can inspire future technological applications in bioelectronics. | Keywords: | bioelectronics;cable bacteria;conductive AFM;electroactive bacteria | Document URI: | http://hdl.handle.net/1942/31281 | ISSN: | 2366-7478 | e-ISSN: | 2366-7478 | DOI: | 10.1002/adbi.202000006 | ISI #: | 000535014500001 | Rights: | 2020 The Authors.
