Emmy Noether Research Group for Organosulfur Cycling

Eileen Kröber's research focuses on organic sulfur compounds which are produced in our oceans and play an important role in climate regulation. These compounds are produced in large quantities in seagrass beds, mangroves and coral reefs – habitats where numerous worms and mussels obtain their nutrition with the help of symbiotic bacteria. This is where Kröber's research comes in: To date, it is not known to what extent such symbioses use the climate-cooling sulfur compounds as a source of energy and sulfur and thus reduce their release into the environment.

Specifically, in the Emmy Noether junior research group that will now be established, Kröber wants to investigate how organic sulfur compounds contribute to the nutrition of symbioses. “Although the importance of these compounds for marine biology and ecology is becoming increasingly clear, it is surprisingly not known whether they can be used by symbioses between bacteria and marine animals,” Kröber explains. “My initial results show that organic sulfur compounds are important for the nutrition of symbiotic partners. To gain a deeper understanding of their importance, I will use a variety of different state-of-the-art methods, such as metatranscriptomics, -proteomics and -bolomics, coupled with experiments in the lab.”
