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

Modeling of interspecies electron transfer in anaerobic microbial communities

Current Opinion in Biotechnology, 2021
Interspecies electron transfer (IET) is a key phenomenon in anaerobic ecosystems, which is traditionally modeled as hydrogen transfer. Recently discovered alternative mediated IET (MIET) or direct IET (DIET) offer exciting alternative mechanisms of microbial partnerships that could lead to new strategies for the improvement of biotechnologies. Here, we

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

Electrochemical Enrichment and Isolation of Electrogenic Bacteria from 0.22 µm Filtrate

Microorganisms, 2022
Ultramicrobacteria (UMB) that can pass through a 0.22 µm filter are attractive because of their novelty and diversity. However, isolating UMB has been difficult because of their symbiotic or parasitic lifestyles in the environment.

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.

Novel Outlook in Microbial Ecology: Nonmutualistic Interspecies Electron Transfer

Trends in Microbiology, 2020
Recent advances in microbial electrochemical technologies have revealed the existence of numerous and highly diverse microorganisms able to exchange electrons with electrodes. This diversity could reflect the capacity of microorganisms to release and/or retrieve electrons with each other in natural environments.

Analysis of Mechanisms for Electron Uptake by <i>Methanothrix harundinacea</i> 6Ac During Direct Interspecies Electron Transfer. [PDF]

Int J Mol Sci
Direct 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.

A review of interspecies electron transfer in anaerobic digestion

IOP Conference Series: Earth and Environmental Science, 2019
Abstract Anaerobic digestion (AD) is an effective way to recover energy from organic waste. About 70% of the methane emitted into the atmosphere is derived from the degradation of organic matter by microorganisms under anaerobic conditions.

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 ...

Catabolism and interactions of uncultured organisms shaped by eco-thermodynamics in methanogenic bioprocesses

Microbiome, 2020
Background Current understanding of the carbon cycle in methanogenic environments involves trophic interactions such as interspecies H2 transfer between organotrophs and methanogens. However, many metabolic processes are thermodynamically sensitive to H2
