Electron transport across the cell envelope via multiheme c-type cytochromes in Geobacter sulfurreducens [PDF]
Frontiers in ChemistryExtracellular electron transfer (EET) enables certain microorganisms to respire using soluble and insoluble extracellular electron acceptors by transporting electrons across the cell envelope. Among these, G. sulfurreducens serves as a model organism for

Microbial magnetite oxidation via MtoAB porin-multiheme cytochrome complex in Sideroxydans lithotrophicus ES-1 [PDF]
Applied and Environmental MicrobiologyMost of Earth’s iron is mineral-bound, but it is unclear how and to what extent iron-oxidizing microbes can use solid minerals as electron donors. A prime candidate for studying mineral-oxidizing growth and pathways is Sideroxydans lithotrophicus ES-1, a

Genome-centric metagenomics reveals electroactive syntrophs in a conductive particle-dependent consortium from coastal sediments [PDF]
Nature CommunicationsConductive particles are common in coastal sediments, yet their role in shaping methane-producing communities and pathways remains unclear. We applied genome-resolved metagenomics to a sediment-derived consortium serially transferred for a decade and ...
