Identification of a pathway for electron uptake in Shewanella oneidensis.

ABSTRACT: Extracellular electron transfer (EET) could enable electron uptake into microbial metabolism for the synthesis of complex, energy dense organic molecules from CO₂ and renewable electricity^1-6. Theoretically EET could do this with an efficiency comparable to H₂-oxidation^7,8 but without the need for a volatile intermediate and the problems it causes for scale up⁹. However, significant gaps remain in understanding the mechanism and genetics of electron uptake. For example, studies of electron uptake in electroactive microbes have shown a role for the Mtr EET complex in the electroactive microbe Shewanella oneidensis MR-1^10-14, though there is substantial variation in the magnitude of effect deletion of these genes has depending
