Synergistic Promotion of Direct Interspecies Electron Transfer by Biochar and Fe₃O₄ Nanoparticles to Enhance Methanogenesis in Anaerobic Digestion of Vegetable Waste

Fermentation
When vegetable waste (VW) is used as a sole substrate for anaerobic digestion (AD), the rapid accumulation of volatile fatty acids (VFAs) can impede interspecies electron transfer (IET), resulting in a relatively low biogas production rate. In this study,

Research progress and perspective on sludge anaerobic digestion technology: A bibliometric analysis

Water Science and Technology
Rational disposal of sludge is an ongoing concern. This work is the first attempt for in-depth statistical analysis of anaerobic digestion (AD) research in recent three decades (1986–2022) using both quantitative and qualitative approaches in ...

Conductive materials stimulated direct interspecies electron transfer and application in anaerobic digestion [PDF]

, 2019
Methanation of complex organic substances needs cooperation between syntrophic microorganisms. During this process, electrons and protons or other reducing equivalents are transferred from bacteria to archaea by intermediate shuttles, such as hydrogen. However, this process cannot be completed unless intermediates are readily removed.

Granular Activated Carbon and Organic Loading Interactions in Methane Fermentation: An Inverse Load-Dependent Relationship and Absolute Microbial Abundance Analysis

Fuels
This study addresses volatile fatty acid (VFA) accumulation, a key issue limiting methane fermentation under high organic loading rate (OLR) conditions. Batch experiments were conducted with GAC (0–10%) under various OLRs (1:0.5–1:10) to investigate its ...
