Scientists around Tetyana Milojevic from the Faculty of Chemistry at the University of Vienna are in search of unique biosignatures, which are left on synthetic extraterrestrial minerals by microbial activity. The biochemist and astrobiologist investigates these signatures at her own miniaturized “Mars farm” where she can observe interactions between the archaeon Metallosphaera sedula and Mars-like rocks. These microbes are capable of oxidizing and integrating metals into their metabolism.
The team investigates interactions between Metallosphaera sedula, a microbe that inhabits extreme environments, and different minerals which contain nutrients in form of metals...
