Diazotroph community succession during the VAHINE mesocosm experiment (New Caledonia lagoon) [PDF]

, 2015
The VAHINE mesocosm experiment, conducted in the low-nutrient low-chlorophyll waters of the Noumea lagoon (coastal New Caledonia) was designed to trace the incorporation of nitrogen (N) fixed by diazotrophs into the food web, using large volume (50 m(3))

Global biogeography of N₂-fixing microbes: nifH amplicon database and analytics workflow [PDF]

Earth System Science Data
Marine dinitrogen (N2) fixation is a globally significant biogeochemical process carried out by a specialized group of prokaryotes (diazotrophs), yet our understanding of their ecology is constantly evolving. Although marine N2 fixation is often ascribed

Similar Diversity of Alphaproteobacteria and Nitrogenase Gene Amplicons on Two Related Sphagnum Mosses [PDF]

, 2012
Sphagnum mosses represent a main component in ombrotrophic wetlands. They harbor a specific and diverse microbial community with essential functions for the host. To understand extend and degree of host specificity, Sphagnum fallax and S.

Microbial regulation of global macroalgal blooms (green tides): From holobiont interactions to bloom dynamics and biogeochemistry

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Green tides caused by Ulva species have become one of the most serious marine ecological disasters, now impacting many coastal nations around the world. Although climatic and environmental drivers of these macroalgal blooms are well recognized, growing evidence identifies Ulva‐associated microbiota as potential pivotal regulators of bloom ...

Predicting compatibility between ferredoxins and the Fe protein of nitrogenase using in silico protein modeling

Protein Science, Volume 35, Issue 3, March 2026.
Abstract Biological nitrogen fixation is the process by which certain bacteria and archaea use the enzyme nitrogenase to reduce atmospheric nitrogen into bioavailable ammonium. Engineering non‐nitrogen‐fixing organisms, like plants, to use nitrogenase could reduce dependency on synthetic fertilizer and mitigate the environmental impacts of industrial ...

Nanocomposite Reduces Volatile and Aqueous Reactive Nitrogen Losses From Soil Compared to Conventional and Alternative Fertilisers

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Reactive nitrogen losses from agriculture contribute substantially to greenhouse gas emissions, water pollution and ecosystem degradation. Controlled‐release fertiliser technologies offer potential solutions, yet few comprehensively evaluate performance across multiple nitrogen loss pathways and soil types.

Stage‐specific biological nitrogen fixation depends on distinct carbon and nitrogen availability in long‐term fertilized paddy fields

Functional Ecology, Volume 40, Issue 3, Page 692-705, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Industrial Haber–Bosch provides 32 Tg nitrogen (N) per year to global croplands. Such large amounts of N fertilization will reshape soil N cycles. One uncertainty is whether and how these long‐term N inputs impact soil biological N2 fixation (BNF) associated with plant ...

Nitrogenase genes in PCR and RT-PCR reagents: implications for studies of diversity of functional genes

BioTechniques, 2003
Studies of the diversity of microorganisms in the environment have been facilitated by use of PCR and reverse transcription PCR (RT-PCR). Inhibition of the PCR by complex sample matrices and low abundance of some target microorganisms require the use of ...
