Marine dissolved organic matter (DOM) contains more carbon than the combined stocks of
Earth's biota. Organisms in the ocean continuously release a myriad of molecules that …

Polysaccharides are major components of macroalgal and phytoplankton biomass and
constitute a large fraction of the organic matter produced and degraded in the ocean. Until …

Marine algae annually sequester petagrams of carbon dioxide into polysaccharides, which
are a central metabolic fuel for marine carbon cycling. Diatom microalgae produce sulfated …

Brown algae annually convert gigatons of carbon dioxide into carbohydrates, including the
complex extracellular matrix polysaccharide fucoidan. Due to its persistence in the …

The formation of sinking particles in the ocean, which promote carbon sequestration into
deeper water and sediments, involves algal polysaccharides acting as an adhesive, binding …

Ruminant animals house a dense and diverse community of microorganisms in their rumen,
an enlarged compartment in their stomach, which provides a supportive environment for the …

The ocean has been a regulator of climate change throughout the history of Earth. One key
mechanism is the mediation of the carbon reservoir by refractory dissolved organic carbon …

Algae synthesise structurally complex glycans to build a protective barrier, the extracellular
matrix. One function of matrix glycans is to slow down microorganisms that try to …

Bacterial microcompartments (BMCs) are organelles that segregate segments of metabolic
pathways which are incompatible with surrounding metabolism. BMCs consist of a …

In this study, we investigate the maximum physical and biogeochemical potential of
macroalgae open-ocean mariculture and sinking (MOS) as an ocean-based carbon dioxide …
