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 ...

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.

Biochemical Evidence for formate transfer in syntrophic propionate oxidizing cocultures of Syntrophobacter fumaroxidans and Methanospirillum hungatei [PDF]

, 2002
The hydrogenase and formate dehydrogenase levels in Syntrophobacter fumaroxidans and Methanospirillum hungatei were studied in syntrophic propionate-oxidizing cultures and compared to the levels in axenic cultures of both organisms.

Facilitation of interspecies electron transfer in anaerobic processes through pine needle biochar

Water Science and Technology, 2022
Role of biochar in promoting methanogenesis during anaerobic processes was investigated in this research. Biochar produced from Himalayan pine needles was used as medium for conductive material mediated interspecies electron transfer (CM-IET) amongst the

Syntrophic growth on formate: a new microbial niche in anoxic environments [PDF]

, 2008
Anaerobic syntrophic associations of fermentative bacteria and methanogenic archaea operate at the thermodynamic limits of life. The interspecies transfer of electrons from formate or hydrogen as a substrate for the methanogens is key.

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.

Addition Coupled Electron Transfer (ACET) and Addition Coupled Electron Coupled Proton Transfer (ACPCET) [PDF]

, 2022
The new types of elementary reaction in which a nucleophilic addition (A) to quinones is coupled with electron transfer (ET) and even further proton transfer (PT) are suggested herein by density functional theory calculation, which are called Addition ...
