Chemosynthetic alphaproteobacterial diazotrophs reside in deep-sea cold-seep bottom waters [PDF]
mSystemsNitrogen (N)-fixing organisms, also known as diazotrophs, play a crucial role in N-limited ecosystems by controlling the production of bioavailable N. The carbon-dominated cold-seep ecosystems are inherently N-limited, making them hotspots of N fixation.

Genetic and physiological insights into the diazotrophic activity of a non-cyanobacterial marine diazotroph [PDF]
Environmental Microbiology, 2022 Abstract Nitrogen (N 2 ) fixation, or diazotrophy, supports a large part of primary production in oceans. Culture-independent approaches highlighted the presence in abundance of marine non-cyanobacterial diazotrophs (NCD) but their ecophysiology remains elusive, mostly because of ...

Draft Genome Sequences of Switchgrass Diazotrophs
Microbiology Resource Announcements, 2021 We report the draft genome sequences of five native nitrogen-fixing bacteria associated with roots of switchgrass isolated from the Tallgrass Prairies of Oklahoma. Nitrogen-fixing genes, including the nif cluster, are conserved across the Klebsiella and Kosakonia ...

Seasonal and spatial patterns in diazotroph community composition at Station ALOHA
Frontiers in Marine Science, 2023 Dinitrogen (N2) fixation is carried out by specialized microbes, called diazotrophs, and is a major source of nitrogen supporting primary production in oligotrophic oceans.

Diazotrophy in the Indian Ocean: Current understanding and future perspectives
Limnology and Oceanography Letters, 2023 Dinitrogen (N2) fixation provides the major source of reactive nitrogen in the open ocean, sustaining biological productivity. The Indian Ocean (IO) covers 22% of the ocean surface, while it only represents 1% of the global diazotroph database.
