From the Earth’s surface to the deep biosphere

 The section Geomicrobiology investigates geomicrobiological processes both on the Earth’s surface including the critical zone and in the ’deep biosphere‘, which supposedly plays a fundamental role within the global biogeochemical cycles over short and long time scales. Our research focuses on the development and distribution of microbial life in terrestrial environments particularly in extreme habitats such as permafrost, deserts, lake sediments and the deep subsurface in continental areas. We analyse the dynamics and processes of microbial communities and the related complex geologic-biological interactions.

We established the novel Helmholtz Laboratory for Integrated Geological and Biological Research (GeoBioLab) as an interdisciplinary platform for joint activities of scientists from various disciplines including microbiology/molecular biology, (bio)geochemistry, bioinformatics, and geomorphology to address our scientific questions in a wide range of environments and disciplines. In addition to basic research, we also work on translating suitable results into applications. These include, for example, the development of equipment for sediment sampling and sample preparation or the utilization of the genetic resources represented by our type culture collection of extremophilic microorganisms for industrial or biotechnological applications.

The Section Geomicrobiology focuses on 3 main topics:

  1. Impact of microorganisms on Earth’s surface development: Understanding the mechanisms and processes of shaping the Earth's surface is of fundamental interest to various disciplines in geosciences. Microorganisms play a key role for the initial soil development and nutrient accumulation, and suggest therefore their enormous potential to shape the terrestrial Earth surface in close interrelation with climate and tectonic forces.
  2. Microbial carbon dynamics in organic-rich sediments: Microbial communities of the terrestrial surface and subsurface drive the formation and consumption of the greenhouse gases (GHG) CO2 and CH4. They are thus key reagents of climate-induced feedbacks on our Earth surface capable both of accelerating and mitigating Global Change. For projecting their response to climate change, we seek unknown microbial sources and sinks of GHG, and study their process rates and community responses.
  3. The deep biosphere: The pore space in sediments and fractures in hard rocks form a vast ecosystem that spans around the entire planet. Despite its gigantic size we still have very little knowledge about the inhabitants, their metabolic capabilities and their interaction with both their geologic surrounding and the surface world. Our research focuses on several aspects of the deep biosphere, covering a wide range of topics and environments including lakes, deep subseafloor habitats, terrestrial gas seeps and permafrost.
