Conductive material engineered direct interspecies electron transfer (DIET) in anaerobic digestion: Mechanism and application

Environmental Technology & Innovation, 2020
Abstract Biological syntrophy can be defined as a nutritional condition where various syntrophic microorganisms mutually synergize their metabolic activities to break down complex organic substrates that cannot be otherwise catabolized by either individually.

Direct interspecies electron transfer (DIET) can be suppressed under ammonia-stressed condition – Reevaluate the role of conductive materials

Water Research, 2020
Thermal hydrolysis pretreatment (THP) and anaerobic digestion (AD) integrated (THP-AD) process is a promising process for sludge management. However, the high ammonia production during the THP-AD process severely affects system's stability and performance.

Sparking Anaerobic Digestion: Promoting Direct Interspecies Electron Transfer to Enhance Methane Production

iScience, 2020
Anaerobic digestion was one of the first bioenergy strategies developed, yet the interactions of the microbial community that is responsible for the production of methane are still poorly understood. For example, it has only recently been recognized that

Different outer membrane c‐type cytochromes are involved in direct interspecies electron transfer to Geobacter or Methanosarcina species

mLife, 2022
Direct interspecies electron transfer (DIET) may be most important in methanogenic environments, but mechanistic studies of DIET to date have primarily focused on cocultures in which fumarate was the terminal electron acceptor.
