Real-Time Monitoring of Subsurface Microbial Metabolism with Graphite Electrodes
Frontiers in Microbiology, 2014 Monitoring in situ microbial activity in anaerobic submerged soils and aquatic sediments can be labor intensive and technically difficult, especially in dynamic environments in which a record of changes in microbial activity over time is desired ...

e-Biologics: Fabrication of Sustainable Electronics with “Green” Biological Materials
mBio, 2017 The growing ubiquity of electronic devices is increasingly consuming substantial energy and rare resources for materials fabrication, as well as creating expansive volumes of toxic waste. This is not sustainable.

Comparative proteomics of a versatile, marine, iron‐oxidizing chemolithoautotroph
Environmental Microbiology, Volume 26, Issue 6, June 2024.In this study, we identified proteins that were upregulated under iron‐oxidizing conditions. Notably, we highlight a periplasmic di‐heme cytochrome c that is associated with a putative redox complex spanning the inner membrane, periplasm, outer membrane, and extracellular space.

Kabelbakterienskelette als katalytisch aktive Elektroden
Angewandte Chemie, Volume 136, Issue 6, February 5, 2024.Biologische Kabel als Elektroden: Elektrisch leitfähige filamentöse Kabelbakterienskelette wurden als freistehende biologische Elektroden verwendet und zeigen eine katalytische Selektivität für Sauerstoff. Die Skelette wandeln Wasser in Sauerstoff um, und umgekehrt, Sauerstoff zurück zu Wasser.

Insights into the various mechanisms by which Shewanella spp. induce and inhibit steel corrosion
npj Materials Degradation, 2023 Shewanella species are frequently selected as model strains to investigate microbially influenced steel corrosion. This selection is due to their relevance for corrosion, but also because of their easy cultivation in aerobic media.

Cable Bacteria Skeletons as Catalytically Active Electrodes
Angewandte Chemie International Edition, Volume 63, Issue 6, February 5, 2024.Biological cables as electrodes: Electrically conducting filamentous cable bacteria skeletons were used as free‐standing biological electrodes and displayed catalytic selectivity towards oxygen. The skeletons convert water to oxygen and oxygen back to water.
