Direct Observation of Electrically Conductive Pili Emanating from Geobacter sulfurreducens [PDF]

mBio, 2021
Geobacter sulfurreducens is a model microbe for elucidating the mechanisms for extracellular electron transfer in several biogeochemical cycles, bioelectrochemical applications, and microbial metal corrosion.

Bottom-Up Fabrication of Protein Nanowires via Controlled Self-Assembly of Recombinant Geobacter Pilins

mBio, 2019
Metal-reducing bacteria in the genus Geobacter use a complex protein apparatus to guide the self-assembly of a divergent type IVa pilin peptide and synthesize conductive pilus appendages that show promise for the sustainable manufacturing of protein ...

Electromicrobiology : a systems perspective. [PDF]

, 2012
The ability of microorganisms to exchange electrons directly with their environment has large implications for our knowledge of industrial as well as for environmental processes. For decades, it has been known that microbes can use electrodes as electron acceptors in microbial fuel cell settings.

Conservation of Energetic Pathways for Electroautotrophy in the Uncultivated Candidate Order Tenderiales [PDF]

mSphere, 2022
Electromicrobiology can be used to understand extracellular electron uptake in previously undescribed chemolithotrophs. Enrichment and characterization of the uncultivated electroautotroph “Candidatus Tenderia electrophaga” using electromicrobiology led ...

Towards bioprocess engineering of cable bacteria: Establishment of a synthetic sediment. [PDF]

Microbiologyopen
In this study, we successfully cultivated the cable bacteria strain Electronema aureum GS on a newly developed synthetic sediment, marking the first instance of such cultivation on synthetic rather than natural sediment. The combination of this synthetic sediment and a specially designed sediment bioreactor enables reproducible cultivation of cable ...

Indications for a genetic basis for big bacteria and description of the giant cable bacterium Candidatus Electrothrix gigas sp. nov.

Microbiology Spectrum, 2023
Bacterial cells can vary greatly in size, from a few hundred nanometers to hundreds of micrometers in diameter. Filamentous cable bacteria also display substantial size differences, with filament diameters ranging from 0.4 to 8 µm.

Modulation of butyrate-degrading methanogenic communities by conductive materials [PDF]

, 2021
Butyrate is a volatile fatty acid commonly present in anaerobic bioreactors. Previous research showed that methane production (MP) rates from butyrate, by lake sediment microbiomes, doubled by addition of carbon nanotubes, which was accompanied by ...

Physiologic, Genomic, and Electrochemical Characterization of Two Heterotrophic Marine Sediment Microbes from the Idiomarina Genus

Microorganisms, 2022
Extracellular electron transfer (EET), the process that allows microbes to exchange electrons in a redox capacity with solid interfaces such as minerals or electrodes, has been predominantly described in microbes that use iron during respiration. In this

Large Filamentous Bacteria Isolated From Sulphidic Sediments Reveal Novel Species and Distinct Energy and Defence Mechanisms for Survival. [PDF]

Environ Microbiol
In this study, we used micromanipulation and omics to analyse 15 large filamentous bacteria collected from sulphidic sediments off Chile. We discovered novel species from various phyla, and diverse metabolic pathways and defence mechanisms were identified, highlighting their adaptability to the sediment–water interface and resilience against phage ...
