Filamentous bacteria transport electrons over centimetre distances
TLDR
Evidence is presented that the native conductors are long, filamentous bacteria that abounded in sediment zones with electric currents and along their length they contained strings with distinct properties in accordance with a function as electron transporters.

Shewanella oneidensis MR-1 nanowires are outer membrane and periplasmic extensions of the extracellular electron transport components
TLDR
Using in vivo fluorescence measurements, immunolabeling, and quantitative gene expression analysis, it is demonstrated that S. oneidensis MR-1 nanowires are extensions of the outer membrane and periplasm that include the multiheme cytochromes responsible for EET, rather than pilin-based structures as previously thought.

Electrical transport along bacterial nanowires from Shewanella oneidensis MR-1
TLDR
Electro transport measurements along individually addressed bacterial nanowires derived from electron-acceptor–limited cultures of the dissimilatory metal-reducing bacterium Shewanella oneidensis MR-1 allow for bacterial Nanowires to serve as a viable microbial strategy for extracellular electron transport.

Electrokinesis is a microbial behavior that requires extracellular electron transport
TLDR
Electrokinesis is defined as a behavioral response that requires functional extracellular electron transport that is observed as an increase in cell swimming speeds and lengthened paths of motion that occur in the proximity of a redox active mineral surface or the working electrode of an electrochemical cell.

Multistep hopping and extracellular charge transfer in microbial redox chains.
TLDR
This work proposes that multistep hopping in redox chains constitutes a viable strategy for extracellular charge transfer in microbial biofilms and calculated the current-voltage characteristics and found the results to be in good agreement with I-V measurements across and along individual microbial nanowires produced by the bacterium Shewanella oneidensis MR-1.

Regulation of Gene Expression in Shewanella oneidensis MR-1 during Electron Acceptor Limitation and Bacterial Nanowire Formation
ABSTRACT In limiting oxygen as an electron acceptor, the dissimilatory metal-reducing bacterium Shewanella oneidensis MR-1 rapidly forms nanowires, extensions of its outer membrane containing the…
