Rhizosphere Diazotrophs and Other Bacteria Associated with Native and Encroaching Legumes in the Succulent Karoo Biome in South Africa

Microorganisms, 2022
Total and diazotrophic bacteria were assessed in the rhizosphere soils of native and encroaching legumes growing in the Succulent Karoo Biome (SKB), South Africa.

Taxonomy and Phylogeny of Diazotrophs

, 1998
The biodiversity of nitrogen-fixing organisms is huge. Taxonomic and phylogenetic research is needed to structure this diversity, to facilitate communication among scientists, and to increase our understanding of the evolution and biology of diazotrophs.

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 .

Redox Regulation in Diazotrophic Bacteria in Interaction with Plants

Antioxidants, 2021
Plants interact with a large number of microorganisms that greatly influence their growth and health. Among the beneficial microorganisms, rhizosphere bacteria known as Plant Growth Promoting Bacteria increase plant fitness by producing compounds such as

Diazotroph Genomes and Their Seasonal Dynamics in a Stratified Humic Bog Lake

Frontiers in Microbiology, 2020
Aquatic N-fixation is generally associated with the growth and mass development of Cyanobacteria in nitrogen-deprived photic zones. However, sequenced genomes and environmental surveys suggest active aquatic N-fixation also by many non-cyanobacterial ...

Bleaching forces coral’s heterotrophy on diazotrophs and Synechococcus [PDF]

The ISME Journal, 2019
Abstract Coral reefs are threatened by global warming, which disrupts the symbiosis between corals and their photosynthetic symbionts (Symbiodiniaceae), leading to mass coral bleaching. Planktonic diazotrophs or dinitrogen (N2)-fixing prokaryotes are abundant in coral lagoon waters and could be an alternative nutrient source for corals ...

Influence of N, P, and Fe availability on Braarudosphaera bigelowii, Trichodesmium, Crocosphaera, and noncyanobacterial diazotrophs: a review

Frontiers in Marine Science
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 have been conducted studying the effects of nutrients such as total ...

Optimizing the Growth Conditions of the Selected Plant-Growth-Promoting Rhizobacteria Paenibacillus sp. MVY-024 for Industrial Scale Production

Biology, 2022
In this study, thirteen isolates, which were possibly expected to fix nitrogen, were isolated from soil and pea root nodules and identified by the gene analysis of 16S rDNA sequences.

Haloalkaliphilic diazotrophs in soda solonchak soils [PDF]

FEMS Microbiology Ecology, 2008
Nitrogen fixation (NF) potential was measured in more than 40 samples of soda solonchak soils with the pH of water extract between 9.5 and 11.0 collected in several locations of Central Asia and in Egypt, using the acetylene reduction method. NF was detected in most of the samples.

Global marine metagenomics reveals the functional diversity and ecological adaptations of diazotrophs across marine ecosystems

Communications Earth & Environment
Biological nitrogen fixation by diazotrophs is vital for nitrogen supply and marine productivity. Despite extensive documentation of diverse diazotrophs, their functional diversity and adaptive strategies across ecosystems remain largely underexplored ...
