Contrasted Reactivity to Oxygen Tensions in Frankia sp. Strain CcI3 throughout Nitrogen Fixation and Assimilation [PDF]

, 2014
Reconciling the irreconcilable is a primary struggle in aerobic nitrogen-fixing bacteria. Although nitrogenase is oxygen and reactive oxygen species-labile, oxygen tension is required to sustain respiration.

Diversity and Plant Growth‐Promoting Potential of Duckweed‐Associated Bacteria on Wolffia globosa Biomass Production and Nutritional Quality

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Co‐cultivation screening of 116 duckweed‐associated bacteria revealed isolates that enhanced Wolffia globosa biomass up to 77.75%, with Pseudomonas toyotomiensis W5–11 increasing dry weight 3.18‐fold and chlorophyll content 2.75‐fold, demonstrating their potential as biofertilisers for sustainable duckweed production.

Reprogramming of Gene Transcripts and Metabolites by the Wild Soybean Endophyte Pseudomonas sp. 77S3 Improves Soybean Salt Tolerance

Plant Biotechnology Journal, Volume 24, Issue 4, Page 2704-2721, April 2026.
ABSTRACT Soybean is a critical source of protein and vegetable oil worldwide. Expanding its cultivation into salinity lands represents a promising strategy for increasing production; however, soil salinity severely limits soybean growth by disrupting physiological and metabolic homeostasis.

Heterotrophic N2-fixation contributes to nitrogen economy of a common wetland sedge, Schoenoplectus californicus.

PLoS ONE, 2018
A survey of the ecological variability within 52 populations of Schoenoplectus californicus (C.A. Mey.) Soják across its distributional range revealed that it is commonly found in nitrogen (N) limited areas, but rarely in phosphorus limited soils.

High nitrogen fixation and Braarudosphaera presence in the North Sea

Limnology and Oceanography, Volume 71, Issue 3, March 2026.
Abstract Nitrogen fixation, the microbial conversion of dinitrogen gas to ammonia, is a key nitrogen source and critical for sustaining marine productivity. We investigated the diversity and activity of nitrogen‐fixers in surface waters of the North Sea and Norwegian coast during July 2023.
