mBio, 2018 Cytochrome-to-cytochrome electron transfer and electron transfer along conduits of multiple extracellular magnetite grains are often proposed as strategies for direct interspecies electron transfer (DIET) that do not require electrically conductive pili (

Promoting direct interspecies electron transfer with activated carbon
Energy & Environmental Science, 2012 Granular activated carbon (GAC) is added to methanogenic digesters to enhance conversion of wastes to methane, but the mechanism(s) for GAC's stimulatory effect are poorly understood. GAC has high electrical conductivity and thus it was hypothesized that one mechanism for GAC stimulation of methanogenesis might be to facilitate direct interspecies ...

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

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 ...

Methanobacterium Capable of Direct Interspecies Electron Transfer [PDF]
Environmental Science & Technology, 2020 Direct interspecies electron transfer (DIET) from bacteria to methanogens is a revolutionary concept for syntrophic metabolism in methanogenic soils/sediments and anaerobic digestion. Previous studies have indicated that the potential for DIET is limited to methanogens in the Methanosarcinales, leading to the assumption that an abundance of other types

Analysis of Mechanisms for Electron Uptake by <i>Methanothrix harundinacea</i> 6Ac During Direct Interspecies Electron Transfer. [PDF]
Int J Mol SciDirect interspecies electron transfer (DIET) is a syntrophic metabolism wherein free electrons are directly transferred between microorganisms without the mediation of intermediates such as molecular hydrogen or formate. Previous research has demonstrated that Methanothrix harundinacea 6Ac is capable of reducing carbon dioxide through DIET.
