Abstract Models are widely used tools in aquatic science to understand the mechanism of phytoplankton growth and anticipate the occurrence of harmful algal blooms. However, model parameterization remains challenging and issues that may introduce prediction uncertainty exist.

Survival of diazotrophic cyanobacteria in soil
World Journal of Microbiology & Biotechnology, 1993The survival under drough conditions for one year of 12 heterocystous cyanobacterial strains inoculated in three different soil types (silt clay, calcareous clay and silt loam) gave the highest survival (50%) forScytonema 208L.Fischerella 288L andNostoc OP25 also showed significant survival.

Science, 2021
Nitrogen Fixation About half of the planet's nitrogen fixation occurs out at sea by prokaryote diazotrophs, yet we still have a poor understanding of which ones do what. Karlusich et al. applied a combination of image capture and nitrogenase gene ( nifH ) sequencing on globally gathered data to map diazotrophs sampled at different depths.

Life in grasses: diazotrophic endophytes
Trends in Microbiology, 1998N2-fixing bacteria such as Azoarcus spp., Herbaspirillum spp, and Acetobacter diazotrophicus can infect the interior of gramineous plants without causing symptoms of plant disease but do not survive in soil. Like phytopathogens, they can penetrate into central tissues and spread systemically.

Microbial mats have been the focus of scientific research for a few decades. These small-scale ecosystems are examples of versatile benthic communities of microorganisms, usually dominated by phototrophic bacteria (e.g., Krumbein et al., 1977; Jørgensen et al., 1983). They develop as vertically stratified populations of functionally different groups of

The Diazotroph as an Endophyte and How a Diazotroph Interacts with Its Plant Host
2021The “diazotrophs” are dinitrogen-fixing (N2-fixing) microorganisms that include members of the bacteria and archaea, and are functionally important microbes that convert gaseous N2 to ammonia (NH3). There are endophytic diazotrophic bacteria that live within plant tissues for at least part of the plants life cycle without causing apparent disease ...

Description and Classification of Diazotrophs
1975In comparative biology it is normally observed that organisms possessing a common function also tend to have certain distinguishing physiological, metabolic, structural and genetic characteristics. The organisms which can use N2 to meet their nitrogen requirement, however, appear to violate this rule: except for the ability to fix N2, these organisms ...

Nitrogen fixation and diazotroph diversity in groundwater systems
The ISME Journal, 2023Abstract Biological nitrogen fixation (BNF), the conversion of N2 into bioavailable nitrogen (N), is the main process for replenishing N loss in the biosphere. However, BNF in groundwater systems remains poorly understood. In this study, we examined the activity, abundance, and community composition of diazotrophs in groundwater in the ...

Diversity of Nitrogenase Systems in Diazotrophs
Journal of Integrative Plant Biology, 2006Abstract Nitrogenase is a metalloprotein complex that catalyses the reaction of biological nitrogen fixation. At least three genetically distinct nitrogenase systems have been confirmed in diazotrophs, namely Nif, Vnf, and Anf, in which the active‐site central metals are Mo, V, and Fe, respectively.

Biogeography of diazotrophic bacteria in soils
World Journal of Microbiology and Biotechnology, 2010This study evaluated diazotrophic bacterial diversity of soils from four different sites in South and North America. Approximately one hundred and thirty-nine thousand partial sequences of the small subunit of the bacterial ribosomal RNA gene generated for a previous study were used for this work.
