Where a circle begins – Germination and early life cycle stages of Myxococcus xanthus With its intriguing social life style, Myxococcus xanthus is one of the most well-known examples of predatory bacteria. These bacteria form multicellular swarms that – like microscopic wolf packs – collectively hunt other microbes, form intricate wave patterns while feeding, and […]
Axel Magalon – Adapting microbial respiration to a ...
Adapting microbial respiration to a changing environment: a lipid affair? How do microorganisms adjust their energy metabolism to changing environments? This seminar explores how membrane lipid composition contributes to this adaptation. Using Escherichia coli as a model, we show that the requirement for cardiolipin depends on the metabolic regime, with a specific contribution to efficient […]
Sybille Lebert – Bacterial ice nucleation as a free...
Bacterial ice nucleation as a freezing survival mechanism on glacier surfaces Microbial communities in glacial habitats endure extreme conditions such as low temperatures, freeze–thaw cycles, and limited water availability. Microorganisms in these environments possess a range of adaptations to tolerate such stresses. Among these, the ability of certain bacteria to nucleate ice through surface-exposed ice-nucleating […]
Thomas Kaboré – Uncovering novel RNA-mediated regul...
Chaperone proteins in Fe-S cluster biogenesis Iron-sulfur clusters (Fe-S) are critical cofactors required for the activity of many proteins, including components of the oxidative phosphorylation chain, metabolic enzymes, transcription factors, proteins involved in biogenesis of ribosomes and replication/repair of DNA. The Fe-S biogenesis pathway, termed ISC, which functions in bacteria and mitochondria, is complex, involving many […]

Alessandra Lütz – The Role of Space in Population M...
The Role of Space in Population Models A first approach to population models usually involves neglecting the role of space in the dynamics. Such an approach can be useful for isolating mechanisms without the influence of specific spatial characteristics. However, it has been shown that spatial structure can strongly impact population dynamics and may be […]
