Cysteine-Mediated Extracellular Electron Transfer of Lysinibacillus varians GY32
Microbiology Spectrum, 2022 Microbial extracellular electron transfer (EET) is essential in many natural and engineering processes. Compared with the versatile EET pathways of Gram-negative bacteria, the EET of Gram-positive bacteria has been studied much less and is mainly limited

Assembly, growth and conductive properties of tellurium nanorods produced by Rhodococcus aetherivorans BCP1 [PDF]
, 2018 Tellurite (TeO32-) is a hazardous and toxic oxyanion for living organisms. However, several microorganisms can bioconvert TeO32- into the less toxic form of elemental tellurium (Te0).

Thermally activated charge transport in microbial protein nanowires [PDF]
Scientific Reports, 2016 AbstractThe bacterium Geobacter sulfurreducens requires the expression of conductive protein filaments or pili to respire extracellular electron acceptors such as iron oxides and uranium and to wire electroactive biofilms, but the contribution of the protein fiber to charge transport has remained elusive. Here we demonstrate efficient long-range charge

Microbial nanowires: Is the subsurface “hardwired”?
Geophysical Research Letters, 2007 The Earth's shallow subsurface results from integrated biological, geochemical, and physical processes. Methods are sought to remotely assess these interactive processes, especially those catalysed by micro‐organisms. Using saturated sand columns and the metal reducing bacterium Shewanella oneidensis MR‐1, we show that electrically conductive ...

Solvent-Induced Assembly of Microbial Protein Nanowires into Superstructured Bundles
Biomacromolecules, 2021 Protein-based electronic biomaterials represent an attractive alternative to traditional metallic and semiconductor materials due to their environmentally benign production and purification. However, major challenges hindering further development of these materials include (1) limitations associated with processing proteins in organic solvents and (2 ...
