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 ...

Detrimental impact of the Geobacter metallireducens type VI secretion system on direct interspecies electron transfer

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 ...

Enhanced Anaerobic Digestion Using Conductive Materials through Mediation of Direct Microbial Interspecies Electron Transfer: A Review

Fermentation, 2023
The anaerobic digestion (AD) of organic matter is susceptible to the challenges posed by low-speed electron transfer between microorganisms and the limitation of low hydrogen partial pressure, resulting in low methane recovery efficiency and poor system ...

Conductive Adsorbents Enhance Phenol Removal from Wastewater by Direct Interspecies Electron Transfer "Diet"-Based Anaerobic Biodegradation Process

Journal of Environmental Chemical Engineering, 2023
Highlights Carbon cloth stimulates direct interspecies electron transfer (DIET). Carbon cloth completely removes phenol and accelerates methane production rate. The phenol removal is a result of synergetic adsorption-biodegradation processes.

Methane production by Methanothrix thermoacetophila via direct interspecies electron transfer with Geobacter metallireducens

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 ...

Potential interactions between syntrophic bacteria and methanogens via type IV pili and quorum-sensing systems

Environment International, 2020
Interspecies electron transfer plays an important role in syntrophic methanogenesis. Direct interspecies electron transfer (DIET) between syntrophic oxidizers and methanogens via conductive pili has been only confirmed in some specific co-cultures.

Theoretical characterisation of electron tunnelling from granular activated carbon to electron accepting organisms in direct interspecies electron transfer

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

Genomic Insights into Syntrophic Lifestyle of ‘Candidatus Contubernalis alkaliaceticus’ Based on the Reversed Wood–Ljungdahl Pathway and Mechanism of Direct Electron Transfer

Life, 2023
The anaerobic oxidation of fatty acids and alcohols occurs near the thermodynamic limit of life. This process is driven by syntrophic bacteria that oxidize fatty acids and/or alcohols, their syntrophic partners that consume the products of this oxidation,

Putative Extracellular Electron Transfer in Methanogenic Archaea

Frontiers in Microbiology, 2021
It has been suggested that a few methanogens are capable of extracellular electron transfers. For instance, Methanosarcina barkeri can directly capture electrons from the coexisting microbial cells of other species.

Sparking Anaerobic Digestion: Promoting Direct Interspecies Electron Transfer to Enhance Methane Production

iScience, 2020
Anaerobic digestion was one of the first bioenergy strategies developed, yet the interactions of the microbial community that is responsible for the production of methane are still poorly understood. For example, it has only recently been recognized that
