The ocean is home to a diverse and metabolically versatile microbial community that
performs the complex biochemical transformations that drive the nitrogen cycle, including …

Abstract Subtropical gyres cover 26%–29% of the world's surface ocean and are
conventionally regarded as ocean deserts due to their permanent stratification, depleted …

Biological dinitrogen (N2) fixation supplies nitrogen to the oceans, supporting primary
productivity, and is carried out by some bacteria and archaea referred to as diazotrophs …

Cadmium (Cd) contamination poses a considerable threat to human health through grain
enrichment and limits biological nitrogen fixation (BNF) in paddy fields. Biochar has shown …

The high diversity and global distribution of heterotrophic bacterial diazotrophs (HBDs) in
the ocean has recently become apparent. However, understanding the role these largely …

UCYN-A is a globally important nitrogen-fixing symbiotic microbe often found in colder
regions and coastal areas where nitrogen fixation has been overlooked. We present a 3 …

Marine nitrogen (N2) fixation supports significant primary productivity in the global ocean.
However, in one of the most productive regions of the world ocean, the northern Humboldt …

Non-cyanobacterial diazotrophs may be contributors to global marine N 2 fixation, although
the factors controlling their distribution are unclear. Here, we explored what controls the …

Marine biological nitrogen fixation (BNF) is crucial for introducing “new nitrogen” into the
oceans. Over the past 30 years, numerous laboratory and on-board culture experiments …

Marine dinitrogen (N 2) fixation is a globally significant biogeochemical process carried out
by a specialized group of prokaryotes (diazotrophs), yet our understanding of their ecology …
