Probing Synechocystis-arsenic interactions through extracellular nanowires

open access: yesFrontiers in Microbiology, 2016
Microbial nanowires (MNWs) can play an important role in the transformation and mobility of toxic metals/metalloids in environment. The potential role of MNWs in cell-arsenic (As) interactions has not been reported in microorganisms and thus we explored ...

Microbial nanowires and electroactive biofilms [PDF]

open access: yesFEMS Microbiology Ecology, 2018
Geobacter bacteria are the only microorganisms known to produce conductive appendages or pili to electronically connect cells to extracellular electron acceptors such as iron oxide minerals and uranium. The conductive pili also promote cell-cell aggregation and the formation of electroactive biofilms.

Cysteine-Mediated Extracellular Electron Transfer of Lysinibacillus varians GY32

open access: yesMicrobiology 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

Microbial biofilms as living photoconductors due to ultrafast electron transfer in cytochrome OmcS nanowires

open access: yesNature Communications, 2022
Despite enormous potential of solar-driven biocatalysis, most living systems lack photoactive proteins and require toxic and expensive synthetic materials limiting the performance.

Microbial nanowires: Is the subsurface “hardwired”?

open access: yesGeophysical 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 ...

Thermally activated charge transport in microbial protein nanowires [PDF]

open access: yesScientific 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

Enhancing electrical outputs of the fuel cells with Geobacter sulferreducens by overexpressing nanowire proteins

open access: yesMicrobial Biotechnology, 2023
Protein nanowires are critical electroactive components for electron transfer of Geobacter sulfurreducens biofilm. To determine the applicability of the nanowire proteins in improving bioelectricity production, their genes including pilA, omcZ, omcS and ...

Solvent-Induced Assembly of Microbial Protein Nanowires into Superstructured Bundles

open access: yesBiomacromolecules, 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 ...
