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

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

A Review on the Interspecies Electron Transfer of Methane Production in Anaerobic Digestion System
Fermentation, 2023 Anaerobic methanogenesis plays an important role in the sustainable management of high concentration organic wastewater and bioenergy recovery. Interspecies electron transfer (IET) is a new type of mutualistic symbiosis that can accelerate microbial ...

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.

Enhancing methane production from food waste fermentate using biochar. The added value of electrochemical testing in pre-selecting the most effective type of biochar [PDF]
, 2017 Background: Recent studies have suggested that addition of electrically conductive biochar particles is an effective strategy to improve the methanogenic conversion of waste organic substrates, by promoting syntrophic associations between acetogenic and ...

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.

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 ...

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.
