DFG-Emmy-Noether-Group "Hydrothermal Geomicrobiology" (S.I. Bühring)
Hydrothermal vent systems are increasingly recognized as extreme environments of tremendous scientific importance. Their study is of great significance to geochemistry, geobiology and microbiology; they act as windows into the inner Earth and link bio- and geosphere on multiple levels. The limits of life as well as its potential origin are two of the greatest puzzles in biogeosciences, which one can address via the study of hydrothermal systems.
Our group focuses on the exploration of organisms inhabiting submarine shallow-water hydrothermal vent systems. The study of these extremophiles presents an enormous opportunity, because they (1) provide a window into a microbiome characterized by high metabolic versatility and unique adaptations to extreme conditions, they (2) are vastly understudied, and they (3) combine easy accessibility with a wide range of geological, chemical, and biological processes similar to those taking place at deep-sea vents.
