Marine cyanobacteria — tiny ocean plants that produce oxygen and make organic carbon using sunlight and CO2 — are primary engines of Earth’s biogeochemical and nutrient cycles. They nourish other organisms through the provision of oxygen and with their own body mass, which forms the base of the ocean food chain.

The formation of the mineral dolomite is still puzzling scientists. Researchers from the Cluster of Excellence "The Future Ocean" and GEOMAR | Helmholtz Centre for Ocean Research Kiel together with colleagues from Switzerland and Spain have now shown that bacteria can facilitate the formation of dolomite. The study has been published online in the international journal "Geology".

The concept of using chemicals made by bacteria or fungi to treat diseases is hardly new. Penicillin came from the bread mold Penicillium and streptomycin came from bacteria known as actinomycetes, to name two well-known examples. But looking for medically valuable substances in the ocean is relatively new—and very promising. Each kind of marine bacteria produces possibly hundreds of small molecules called secondary metabolites, most of which have never been studied before.
