DiazoTIME: a metabolically-resolved reference database of nitrogen-fixing microbial genomes | Microbiology Resource Announcements Biological nitrogen fixation is performed by “diazotrophs,” which convert dinitrogen gas (N2) to ammonia (NH3) using the nitrogenase enzyme. Determining the distribution of N2-fixing (diazotrophic) mi...

If you are working with diazotrophs, we have a new genome resolved database!

This surprisingly relaxing footage is from SIX MILES under the ocean – and it’s the deepest ecosystem yet discovered

Global importance of nitrogen fixation across inland and coastal waters Biological nitrogen fixation is a key driver of global primary production and climate. Decades of effort have repeatedly updated nitrogen fixation estimates for terrestrial and open ocean systems, yet...

Glad to share our paper revealing that inland and coastal waters, while covering <10% of Earth’s surface, contribute ~20% of global nitrogen fixation! www.science.org/doi/10.1126/... @noc.ac.uk @ird-fr.bsky.social @mioceanologie.bsky.social

Particle-associated N2 fixation by heterotrophic bacteria in the global ocean Heterotrophic bacteria fix N2 in more diverse environments than previously thought, critical for the oceanic nitrogen cycle.
