Invisible alliances: the role of marine symbioses in the global sulphur cycle

Hidden in the ocean, there are fascinating partnerships between microorganisms and animals: chemosynthetic symbioses. These partnerships play a key role in the marine sulfur cycle, which influences both life in the ocean and the climate. Particularly significant are dimethylsulfoniopropionate and dimethyl sulfide, substances which are produced and broken down by marine organisms. Chemosynthetic symbioses utilize and transform these sulfur compounds, potentially shaping the global sulfur cycle and climate regulation.
