Expanding the Diet for DIET: Electron Donors Supporting Direct Interspecies Electron Transfer (DIET) in Defined Co-Cultures [PDF]

Frontiers in Microbiology, 2016
Direct interspecies electron transfer (DIET) has been recognized as an alternative to interspecies H2 transfer as a mechanism for syntrophic growth, but previous studies on DIET with defined co-cultures have only documented DIET with ethanol as the ...

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.

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.
