Microbial Oceanography

📌 New publication in Nature Geoscience by Amano et al., reveals that heterotrophic bacteria, particularly the marine genus Alteromonas, substantially contribute to oceanic dissolved inorganic carbon fixation via anaplerotic pathways, accounting for an estimated ~17% of dark DIC fixation and a significant global carbon flux (~0.2 PgC yr-1).
