The nitrogen input through biological N 2 fixation is essential for life in vast areas of the
global ocean. The belief is that cyanobacteria are the only relevant N 2-fixing (diazotrophic) …

Nitrogen (N) fixation is fueling planktonic production in a multitude of aquatic environments.
In meso-and poly-haline estuaries, however, the contribution of N by pelagic N2 fixation is …

In the present study, we report the nitrogen fixing potential of heterotrophic diazotrophs
isolated from a tropical estuary and adjacent coastal sea. Results of the study revealed that …

A novel high-throughput strategy was developed to determine the calcium precipitation
activity (CPA) of mineralization bacteria used for self-healing of concrete cracks. A bacterial …

The ability to reduce atmospheric nitrogen (N2) to ammonia, known as N2 fixation, is a
widely distributed trait among prokaryotes that accounts for an essential input of new N to a …

Nitrogen fixation in temperate oceans is a potentially important, but poorly understood
process that may influence the marine nitrogen budget. This study determined seasonal …

Estuaries receive substantial anthropogenic nitrogen loading and are mainly considered net
nitrogen sinks. While several studies have identified diverse diazotrophic communities in …

We describe diazotrophs present during a 2015 GEOTRACES expedition through the
Canadian Arctic Gateway (CAG) using nifH metabarcoding. In the less studied Labrador …

Only 1% of marine bacteria are currently culturable using standard laboratory procedures,
and this is a major obstacle for our understanding of the biology of marine microorganisms …

Summary The N2‐fixing (diazotrophic) community in marine ecosystems is dominated by
non‐cyanobacterial microorganisms. Yet, very little is known about their identity, function …
