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.

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.

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 ...

Relative Diazotroph Abundance in Symbiotic Red Sea Corals Decreases With Water Depth
Frontiers in Marine Science, 2019 Microbial dinitrogen (N2) fixation (diazotrophy) is a trait critical for coral holobiont functioning. The contribution of N2 fixation to holobiont nitrogen (N) supply likely depends on the ecological niche of the coral holobiont.

Symbiotic unicellular cyanobacteria fix nitrogen in the Arctic Ocean. [PDF]
, 2018 Biological dinitrogen (N2) fixation is an important source of nitrogen (N) in low-latitude open oceans. The unusual N2-fixing unicellular cyanobacteria (UCYN-A)/haptophyte symbiosis has been found in an increasing number of unexpected environments ...

Expression of the Klebsiella pneumoniae nifH gene in Saccharomyces cerevisiae
Enzyme and Microbial Technology, 1987 Dinitrogenase reductase, a component of a complex and highly regulated prokaryotic enzyme, nitrogenase, is expressed in the eukaryote Saccharomyces cerevisiae. A plasmid pH-ADH-1 was constructed that directs the expression of the Klebsiella pneumoniae nifH gene, encoding dinitrogenase reductase, from the yeast alcohol dehydrogenase I promoter.

Characterization of a nifH-Harboring Bacterial Community in the Soil-Limited Gotjawal Forest
Frontiers in Microbiology, 2019 Using a high-throughput metagenomic approach, we evaluated nifH-harboring bacterial communities and their assembly in the Gotjawal forest, which was naturally formed on basalt rocks with thin layer of soil.
