Structural and functional insights into the conductive pili of Geobacter sulfurreducens revealed in molecular dynamics simulations [PDF]
Physical Chemistry Chemical Physics, 2015 Geobacter sulfurreducens (GS) electronically connects with extracellular electron acceptors using conductive protein filaments or pili. To gain insights into their role as biological nanowires, we investigated the structural dynamics of the GS pilus in ...

Electrically conductive pili: Biological function and potential applications in electronics [PDF]
Current Opinion in Electrochemistry, 2017 Electrically conductive pili (e-pili) enable long-range electron exchange between microorganisms and their extracellular environment and show promise as a ‘green’ electronic material. Most studies have focused on the e-pili of G. sulfurreducens, which play a role in Fe(III) oxide reduction and interspecies electron transfer, and confer conductivity to ...

Electrically conductive pili from pilin genes of phylogenetically diverse microorganisms [PDF]
ISME Journal, 2017 The possibility that bacteria other than Geobacter species might contain genes for electrically conductive pili (e-pili) was investigated by heterologously expressing pilin genes of interest in Geobacter sulfurreducens. Strains of G.

Conductivity of individual Geobacter pili
RSC Advances, 2016 Measurements of the conductivity of hydrated individual pili of Geobacter sulfurreducens that were not subjected to chemical fixation revealed conductivity along cytochrome-free regions comparable to conducting organic polymer nanowires of similar diameter.

Biological synthesis of high-conductive pili in aerobic bacterium Pseudomonas aeruginosa
Applied Microbiology and Biotechnology, 2018Bioelectrical nanowires as ecomaterials have great potential on environmental applications. A wide range of bacteria can express type IV pili (T4P), which are long protein fibers assembled from PilA. The T4P of Geobacter sulfurreducens are well known as "microbial nanowires," yet T4P of Pseudomonas aeruginosa (PaT4P) was believed to be poorly ...

Structural Basis for the High Conductivity of Microbial Pili as Potential Nanowires
Journal of Nanoscience and Nanotechnology, 2020The conductivity of Geobacter sulfurreducens is attributed mainly to its truncated pili, known as microbial nanowires. In this study, we explored the biological factors that limit electron transfer and hence the conductivity of pili, including the types of aromatic residue, distances between aromatic residues, local electrostatic environment around ...

This study aimed to investigate the graphene oxide (GO) conversion by the sulfate-reducing biocathode and its modified effects on performance of the microbial electrolysis cell (MEC). Biocathodes were acclimated with autotrophic sulfate-reducing cultures using medium containing 500 mg L-1 sulfate. Sulfate reductive rate in the MEC was 230 and 135 g m-3
