Geobacter-based syntrophy drives biogenic element cycling in anoxic soils: a review [PDF]
Frontiers in MicrobiologyMicrobial syntrophy is a central organizing principle in anoxic soils, where the degradation of organic matter and the cycling of nitrogen, sulfur, and iron are constrained by electron availability and thermodynamics.

Biofilm Biology and Engineering of Geobacter and Shewanella spp. for Energy Applications
Frontiers in Bioengineering and Biotechnology, 2021 Geobacter and Shewanella spp. were discovered in late 1980s as dissimilatory metal-reducing microorganisms that can transfer electrons from cytoplasmic respiratory oxidation reactions to external metal-containing minerals.

Electroactive Microbiomes: Electron Transfer Mechanisms and Environmental Biotechnology Applications. [PDF]
Environ Microbiol RepElectroactive microbiomes couple direct, mediated, conductive, and interspecies electron transfer with biofilm organisation to drive wastewater treatment, bioremediation, resource recovery, carbon conversion, and biosensing. Their performance depends on balancing electron transfer, mass transport, community structure, and electrode–biofilm interactions
