Thank you, @YaleWestCampus, for highlighting our work with Peter Dahl (@YaleMBB) and Bill Parson (@UWBiochemistry), which demonstrates that in #Geobacter #cytochrome #nanowires, electrons transfer as a quantum-mechanical wave, not as classical particles that hop.
Faced with a microbial mystery hidden deep in the soil, Nikhil Malvankar returned to his roots - with results that could shape the field of quantum computing https://t.co/jjHK43ug4B @Yale @JPhysChem

Great news to start the week!🙃 Bacteria in soil are creating natural "electric grids"! 🌱This breakthrough could be a game-changer for biofuels and climate research.🔬Kudos to the @Yale & @NOVAunl team for this exciting discovery! #HFSPAwardees #Microbiology #Bioelectricity
Crosstalk between 6-Methyladenine & 4-Methylcytosine in #Geobacter sulfurreducens under Extrmely Low-Frequency Electromagnetic Field Exposure
•4mC modification pattern follows the law of a power function
•4mC & 6mA show crosstalk during DNA methylation

Lack of physiological evidence for cytochrome filaments functioning as conduits for extracellular electron transfer

Functional genetic studies demonstrate requirement for e-pili, but not cytochrome nanowires for #Geobacter long-range EET.
Highlights:
• The primary functional evidence for cytochrome filaments enabling long-range EET is the 2005 finding that deleting the gene for G. sulfurreducens gene for OmcS prevented Fe(III) oxide reduction. (Read paper for the explanation of the already existing evidence that OmcZ and OmcE filaments are not essential for long-range EET)
• We reexamined the physiology of the same OmcS-deficient strain from that original 2005 report. It reduces Fe(III) oxide as well as the wild-type, as does a triple mutant in which the genes for the other known filament-forming cytochromes (OmcZ and OmcE) were also deleted.
• The triple cytochrome mutant that reduced Fe(III) oxide displayed e-pili with the same 3 nm diameter morphology and conductance as those produced by E. coli heterologously expressing the G. sulfurreducens PilA pilin gene.
• Fe(III) oxide reduction was inhibited when the pilin gene in cytochrome-deficient mutants was modified to yield poorly conductive 3 nm diameter filaments.
• These results are consistent with the concept that e-pili are required for G. sulfurreducens long-range extracellular electron transfer. In contrast, rigorous physiological functional evidence is lacking for cytochrome filaments serving as conduits for long-range electron transport.
• The energy that G. sulfurreducens invests in producing cytochrome filaments suggests that they provide a physiological benefit. However, the low abundance of cytochrome filaments compared to e-pili (https://t.co/HRfrdEkgWS) makes functional analysis difficult.
• Bottom up approaches to studying the function of cytochrome filaments and other G. sulfurreducens outer surface proteins (https://t.co/1wHAwcqrQy) such as the recently described expression of OmcS in Shewanella (https://t.co/ynGkHiCW6S) may be helpful for elucidating cytochrome filament function.
• On the practical side- While some folks claim that the pilin-based nanowires cannot exist we are genetically tailoring the properties of e-pili expressed in E. coli for specific electronic functions.
