Microbiologists can now measure extremely slow life

Microbiologists at Center for Geomicrobiology have developed a new method for measuring slow life deep down in the seabed.

Bacteria are the only living organisms to produce D-amino acids that deposit a chemical signature in the mud in which they live. Researchers at the Department of Bioscience and the Center for Geomicrobiology at Aarhus University have used this knowledge together with American researchers to develop a method to calculate the activity level of microorganisms in the deepest layers of the seabed.

The results are published in Nature and can provide knowledge about the global carbon cycle and its long-term impact on the climate.
