“Rust never sleeps”- but engineered E. coli biofilms stop even the most aggressive microbial corrosion of steel.
Towards effective, sustainable corrosion mitigation
Glad to see our paper published in Nature Communications
We discovered how novel marine microorganisms interact via geoconductors to produce methane. www.nature.com/articles/s41...

Titanium meets its match in Geobacter
Microbe strips off the metal’s natural protective oxide coating during respiration, exposing the underlying metal to corrosion.

Not long ago we published "Membrane changes during syntrophic interactions of an archaeal–bacterial coculture". Turns out their membrane changes in the process to adapt to this partnership. Always fascinating to see how dynamic these systems are.
