Frontiers in Physiology, 2020 Coral reef ecosystems cannot operate normally without an effective nitrogen cycle. For oligotrophic coral reef areas, coral-associated diazotrophs are indispensable participants in the nitrogen cycle.

Heterotrophic Nitrogen Fixation at the Hyper-Eutrophic Qishon River and Estuary System
Frontiers in Microbiology, 2020 Planktonic heterotrophic diazotrophs (N2-fixers) are widely distributed in marine and freshwater systems, yet limited information is available on their activity, especially in environments with adverse conditions for diazotrophy (e.g., N-rich and ...

Spatial variation in N2-fixation rate and diazotroph activity in the Tropical Atlantic [PDF]
Biogeosciences, 2007 A variety of N2-fixers occur in oligotrophic waters and these diazotrophs make a substantial contribution to the nitrogen budget of the upper water column.

Lipopolysaccharides in diazotrophic bacteria [PDF]
Frontiers in Cellular and Infection Microbiology, 2014 Biological nitrogen fixation (BNF) is a process in which the atmospheric nitrogen (N2) is transformed into ammonia (NH3) by a select group of nitrogen-fixing organisms, or diazotrophic bacteria. In order to furnish the biologically useful nitrogen to plants, these bacteria must be in constant molecular communication with their host plants.

Frontiers in Marine Science, 2018 Specialized prokaryotes performing biological dinitrogen (N2) fixation (“diazotrophs”) provide an important source of fixed nitrogen in oligotrophic marine ecosystems such as tropical and subtropical oceans. In these waters, cyanobacterial photosynthetic

Agrobacterium tumefaciens Is a Diazotrophic Bacterium [PDF]
Applied and Environmental Microbiology, 1990 This is the first report that Agrobacterium tumefaciens can fix nitrogen in a free-living condition as shown by its abilities to grow on nitrogen-free medium, reduce acetylene to ethylene, and incorporate 15 N supplied as 15 N 2 .

Nature Communications, 2022 Nitrogen-fixing (diazotrophic) cyanobacteria provide a critical nutrient input to the ocean. Non-cyanobacterial diazotrophs are also thought to contribute, but they have not been observed to fix nitrogen.

Search for endophytic diazotrophs in barley seeds [PDF]
Brazilian Journal of Microbiology, 2014 Eight endophytic isolates assigned to Pseudomonas, Azospirillum, and Bacillus genera according to pheno-genotypic features were retrieved from barley seeds under selective pressure for nitrogen-fixers. Genetic relationships among related isolates were investigated through RAPD.

Inoculation of diazotrophic bacteria in chicory [PDF]
Horticultura Brasileira, 2020 ABSTRACT Inoculating crops with diazotrophic bacteria constitutes a feasible biotechnological tool to reduce or even avoid the use of nitrogen fertilizers and to improve the nutritional status of crops. However, the potential use of such technology is limited due to the lack of studies in diverse vegetable crops. We evaluated the production of chicory (
