Ethanol-type anaerobic digestion enhanced methanogenic performance by stimulating direct interspecies electron transfer and interspecies hydrogen transfer

Bioresource Technology
Ethanol pre-fermentation of food waste effectively alleviates acidification; however, its effects on interspecies electron transfer remain unknown. This study configured the feed according to COD ratios of ethanol: sodium acetate: sodium propionate: sodium butyrate of 5:2:1.5:1.5 (ethanol-type anaerobic digestion) and 0:5:2.5:2.5 (control), and ...

Direct Interspecies Electron Transfer Between Archaea and Bacteria

2017
Archaea and bacteria living in syntrophic consortia take advantage of the metabolic abilities of their syntrophic partners to overcome energetic barriers and break down compounds that they cannot digest by themselves. Methanogenesis and anaerobic oxidization of methane (AOM) are main processes involved in syntrophic consortia.

Different Routes for Direct Interspecies Electron Transfer with Diverse Electron-Accepting Partners

2022
AbstractDirect interspecies electron transfer (DIET) may be most important in methanogenic environments, but studies to date that have examined the mechanisms for electron transfer from electron-donating partners have primarily focused on co-cultures in which fumarate was the terminal electron acceptor.

[Research advances in direct interspecies electron transfer within microbes].

Ying yong sheng tai xue bao = The journal of applied ecology, 2021
Hydrogen and formic acid have been considered as the intermediate electron transporters among microbes for a long time. In recent years, however, it has been found that direct interspecies electron transfer (DIET) might be an alternative beyond hydrogen/formic acid to transfer electron among microbes.

Advances towards understanding and engineering direct interspecies electron transfer in anaerobic digestion

Bioresource Technology, 2017
Direct interspecies electron transfer (DIET) is a recently discovered microbial syntrophy where cell-to-cell electron transfer occurs between syntrophic microbial species. DIET between bacteria and methanogenic archaea in anaerobic digestion can accelerate the syntrophic conversion of various reduced organic compounds to methane.

Quorum Sensing Enhances Direct Interspecies Electron Transfer in Anaerobic Methane Production

Environmental Science & Technology
Direct interspecies electron transfer (DIET) provides an innovative way to achieve efficient methanogenesis, and this study proposes a new approach to upregulate the DIET pathway by enhancing quorum sensing (QS). Based on long-term reactor performance, QS enhancement achieved more vigorous methanogenesis with 98.7% COD removal efficiency.

Comparing the effects of magnetite-mediated direct interspecies electron transfer with biogas mixing-driven interspecies hydrogen transfer on anaerobic digestion

Chemosphere
Although the promotive effect of direct interspecies electron transfer (DIET) on methane production has been well-documented, the practical applicability of DIET in different scenarios have not yet been systematically studied. This study compared the effects of magnetite-mediated DIET with conventional biogas mixing-driven interspecies hydrogen ...

Interspecies Electron Transfer in environmental and engineered syntrophic systems

2014
Syntrophic Interspecies Electron Transfer (IET) has been observed in anoxic environments and mainly requires intermediates such as hydrogen or formate as electron carriers. However direct IET (DIET) is also possible and requires that electrons are transferred via membrane-bound proteins or conductive appendages.

Syntrophic methane production from volatile fatty acids: Focus on interspecies electron transfer

Science of The Total Environment
Methane is a renewable biomass energy source produced via anaerobic digestion (AD). Interspecies electron transfer (IET) between methanogens and syntrophic bacteria is crucial for mitigating energy barriers in this process. Understanding IET is essential for enhancing the efficiency of syntrophic methanogenesis in anaerobic digestion.
