Abstract

Direct interspecies electron transfer (DIET) via electrically conductive minerals can play a role in the anaerobic oxidation of petroleum hydrocarbons in contaminated sites and can be exploited for the development of new, more effective bioremediation approaches.

Highlights

  • Link: Northumbria University has developed Northumbria Research Link (NRL) to enable users to access the University’s research output

  • The first observation of a direct interspecies electron transfer (DIET) association was between two Geobacter species, Geobacter metallireducens and Geobacter sulfurreducens, grown on a medium provided with an electron donor for the first species, and an electron acceptor for the other species

  • Funding Information European Union’s Horizon 2020 project ELECTRA under grant agreement No 826244. This disruptive discovery shook up a consolidated paradigm according to which the exchange of electrons among microbes, proceeds via molecular diffusion of soluble molecules such as H2 or formate (Stams and Plugge, 2009; Schink and Stams, 2013)
