Algal-bacterial interactions regulate the production and fate of marine particulate organic carbon (POC), yet their capacity to generate long-lived carbon sinks remains unclear. Using a two-year, nutrient-self-sustaining co-culture of Synechococcus and its mutualistic microbiota, we demonstrate that sustained algal-bac...
Macroalgae, the dominant primary producers of Earth’s most productive coastal vegetated ecosystems and a vital component driving ocean carbon sequestration, produce ∼5 to 80% of their net primary productivity as dissolved organic carbon (DOC). However, the global extent, fate, and contribution of this macroalgae-derive...

Phytoplankton are primarily confined to the sunlit epipelagic zone, yet intact algal cells persist in the ocean’s mesopelagic twilight zone where light is minimal. However, their survival strategies in the deeper ocean remain unknown. Here, we isolate Chaetoceros sp. DS1 from 1000 m depth and reveal its survival mechan...
