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 ...

Biochar@MIL-88A(Fe) Accelerates Direct Interspecies Electron Transfer and Hydrogen Transfer in Waste Activated Sludge Anaerobic Digestion: Exploring Electron Transfer and Biomolecular Mechanisms.

Environmental Research
Adding additives exogenously is an effective strategy to enhance methanogenic activity and improve AD stability. Corn straw-based biochar@MIL-88A(Fe) (BM) was synthesized herewith and used as an exogenous additive to boost methane (CH4) production. After

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.

Interspecies electron transfer and microbial interactions in a novel Fe(II)-mediated anammox coupled mixotrophic denitrification system.

Bioresource Technology
This study effectively coupled anammox and mixotrophic denitrification at a high nitrogen load rate of 6.84 g N/L/d with 40 mg/L Fe(II). Fe(II) enhanced the activity of nitrate reductase, nitrite reductase, and hydrazine dehydrogenase enzymes ...

Allophane improves anaerobic digestion of chicken manure by alleviating ammonia inhibition and intensifying direct interspecies electron transfer.

Bioresource Technology
Synthesized allophane was employed in anaerobic digestion of chicken manure to improve the stability and methane production under ammonia inhibition. Adding 0.5 %, 1.0 % and 1.5 % (w/w) allophane increased the methane production by 261 ∼ 350 % compared ...
