Environmental Conditions Outweigh Geographical Contiguity in Determining the Similarity of nifH-Harboring Microbial Communities in Sediments of Two Disconnected Marginal Seas

Frontiers in Microbiology, 2016
Ecological evidence suggests that heterotrophic diazotrophs fueled by organic carbon respiration in sediments play an important role in marine nitrogen fixation. However, fundamental knowledge about the identities, abundance, diversity, biogeography, and

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.

Microbiome of Trichodesmium Colonies from the North Pacific Subtropical Gyre

Frontiers in Microbiology, 2017
Filamentous diazotrophic Cyanobacteria of the genus Trichodesmium, often found in colonial form, provide an important source of new nitrogen to tropical and subtropical marine ecosystems.

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 ...

Anthropogenic impact on diazotrophic diversity in the mangrove rhizosphere revealed by nifH pyrosequencing

Frontiers in Microbiology, 2015
Diazotrophs in the mangrove rhizosphere play a major role in providing new nitrogen to the mangrove ecosystem and their composition and activity are strongly influenced by anthropogenic activity and ecological conditions.

Low abundance of phytophagous nematodes under invasive exotic Pinus elliottii – enemy release and plant–soil feedbacks

New Phytologist, Volume 249, Issue 6, Page 3060-3071, March 2026.
Summary According to the enemy release hypothesis (ERH), the fitness of exotic plants and their capacity to become invasive in their area of introduction may partly be attributable to the loss of their natural enemies. Invasive species may also benefit from modifying soil attributes and thereby creating a positive soil–plant feedback.

Nitrogen Fertilization Reduces Nitrogen Fixation Activity of Diverse Diazotrophs in Switchgrass Roots

Phytobiomes Journal, 2020
The use of synthetic nitrogen fertilizers to grow biofuel crops adds to the economic and environmental costs of biomass production. Biological nitrogen fixation provides an alternative, eco-friendly source of nitrogen for leguminous plants and some ...

Genome Analysis Reveals Diversity and Functional Potential of Novel Janthinobacterium Species From Subarctic Soils

MicrobiologyOpen, Volume 15, Issue 1, February 2026.
The Pseudomonadota are abundant and diverse members of high‐latitude soils. Here, we describe two novel species, Janthinobacterium silvisoli and Janthinobacterium saanense, of the order Burkholderiales, isolated from tundra heath and northern boreal forest soils.

Spatial and Temporal Variability of Microbial Nitrogen Cycling Genes in Arctic Streams

Global Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract The Arctic is undergoing rapid climate change, with thawing permafrost and shifts in vegetation altering nitrogen (N) delivery into streams. These changes can significantly affect microbial biofilm diversity and functional roles, yet knowledge of streambed microbial biofilms remains scarce across the Arctic.
