Detrimental impact of the Geobacter metallireducens type VI secretion system on direct interspecies electron transfer [PDF]
Microbiology Spectrum, 2023 Direct interspecies electron transfer (DIET) is important in anaerobic communities of environmental and practical significance. Other than the need for close physical contact for electrical connections, the interactions of DIET partners are poorly ...

Plugging in or Going Wireless: Strategies for Interspecies Electron Transfer [PDF]
Frontiers in Microbiology, 2014 Interspecies exchange of electrons enables a diversity of microbial communities to gain energy from reactions that no one microbe can catalyze. The first recognized strategies for interspecies electron transfer were those that relied on chemical ...

Methane production by Methanothrix thermoacetophila via direct interspecies electron transfer with Geobacter metallireducens [PDF]
mBio, 2023 Methanothrix is widely distributed in natural and artificial anoxic environments and plays a major role in global methane emissions. It is one of only two genera that can form methane from acetate dismutation and through participation in direct ...

Theoretical characterisation of electron tunnelling from granular activated carbon to electron accepting organisms in direct interspecies electron transfer [PDF]
Scientific Reports, 2022 Direct interspecies electron transfer (DIET) has been identified as an efficient metabolism between symbiotically interacting organisms. One method of DIET uses conductive materials (e.g., granular activated carbon (GAC)) as a medium to shuttle electrons

Different outer membrane c‐type cytochromes are involved in direct interspecies electron transfer to Geobacter or Methanosarcina species [PDF]
mLife, 2022 Direct interspecies electron transfer (DIET) may be most important in methanogenic environments, but mechanistic studies of DIET to date have primarily focused on cocultures in which fumarate was the terminal electron acceptor.

Transcriptomic and genetic analysis of direct interspecies electron transfer. [PDF]
Appl Environ Microbiol, 2013 ABSTRACT The possibility that metatranscriptomic analysis could distinguish between direct interspecies electron transfer (DIET) and H 2 interspecies transfer (HIT) in anaerobic communities was investigated by comparing gene transcript abundance in cocultures in which Geobacter sulfurreducens

Direct interspecies electron transfer enables anaerobic oxidation of sulfide to elemental sulfur coupled with CO2-reducing methanogenesis [PDF]
iScience, 2023 Summary: Electric syntrophy between fatty acid oxidizers and methanogens through direct interspecies electron transfer (DIET) is essential for balancing acidogenesis and methanogenesis in anaerobic digestion.

Modelling extracellular limitations for mediated versus direct interspecies electron transfer. [PDF]
ISME J, 2016 Abstract Interspecies electron transfer (IET) is important for many anaerobic processes, but is critically dependent on mode of transfer. In particular, direct IET (DIET) has been recently proposed as a metabolically advantageous mode compared with mediated IET (MIET) via hydrogen or formate.

Direct interspecies electron transfer between Geobacter metallireducens and Methanosarcina barkeri. [PDF]
Appl Environ Microbiol, 2014 ABSTRACT Direct interspecies electron transfer (DIET) is potentially an effective form of syntrophy in methanogenic communities, but little is known about the diversity of methanogens capable of DIET. The ability of Methanosarcina barkeri to participate in DIET was evaluated in coculture with ...
