Interspecies electron transfer in methanogenic propionate degrading consortia

Water Research, 2004
Propionate is a key intermediate in the conversion of complex organic matter under methanogenic conditions. Oxidation of this compound requires obligate syntrophic consortia of acetogenic proton- and bicarbonate reducing bacteria and methanogenic archaea.

Dual roles of zero-valent iron in dry anaerobic digestion: Enhancing interspecies hydrogen transfer and direct interspecies electron transfer

Waste Management, 2020
Although commonly viewed as a promising method, dry anaerobic digestion is not been widely applied to dispose of food wastes, especially in developing countries because of its insufficiency in handling with lower mass transfer and high acidic accumulation of the system.

Syntrophy Goes Electric: Direct Interspecies Electron Transfer

Annual Review of Microbiology, 2017
Direct interspecies electron transfer (DIET) has biogeochemical significance, and practical applications that rely on DIET or DIET-based aspects of microbial physiology are growing. Mechanisms for DIET have primarily been studied in defined cocultures in which Geobacter species are one of the DIET partners. Electrically conductive pili (e-pili) can be

Direct Interspecies Electron Transfer in Anaerobic Digestion: A Review

2015
Direct interspecies electrons transfer (DIET) is a syntrophic metabolism in which free electrons flow from one cell to another without being shuttled by reduced molecules such as molecular hydrogen or formate. As more and more microorganisms show a capacity for electron exchange, either to export or import them, it becomes obvious that DIET is a ...

Syntrophy and Interspecies Electron Transfer in Methanogenic Microbial Communities

Microbiology, 2020
Anaerobic digestion of municipal and other organic waste is a microbial process for conversion of complex organic substances to biogas (a renewable energy source) comprising a mixture of methane and CO2, and a stabilized sludge, which may be used as an organic fertilizer.

Challenges in engineering direct interspecies electron transfer for enhanced methanogenesis

Renewable and Sustainable Energy Reviews, 2023
Interspecies electron transfer (IET) between fatty acid-oxidizing bacteria and hydrogenotrophic methanogens is key to stable and efficient methanogenesis in the anaerobic digestion (AD) process. Recently discovered direct IET (DIET) enables energetically and kinetically advantageous methanogenesis and facilitating cell-to-cell electrical connections ...
