Evaluating Oxygen Demand in Mainstream Anammox, A2O and Partial Denitrification/Anammox (PD/A) Processes: A Gradient‐Based Sensitivity Analysis

open access: yesWater and Environment Journal, EarlyView.
This graphical abstract illustrates the oxygen demand reduction potential of the mainstream anammox process compared to conventional A2O and PD/A processes. It visually demonstrates maximum oxygen savings of 28.25% and 18.58%, respectively, under optimal conditions.

Recent Advances in Metal‐Organic Framework Photo‐Electrocatalysts for the Synthesis of Ammonia

open access: yesCarbon Neutralization, Volume 5, Issue 5, September 2026.
This diagram illustrates the role of Metal‐Organic Frameworks (MOFs) in the photocatalytic and electrocatalytic synthesis of ammonia, highlighting their potential as efficient catalysts for sustainable nitrogen fixation under light irradiation and electrode excitation.

Characterization of Abiotic Stress Tolerant Rhizobia as PGPR of Mothbean, Clusterbean and Mungbean Grown in Hyper-arid Zone of Rajasthan

open access: yesInternational Journal of Bio-Resource and Stress Management, 2017
The present investigation was focused on isolation and in vitro characterization of high abiotic stress tolerance, PGPR traits and dinitrogen fixation efficiency among cultivable rhizobia nodulating mothbean, clusterbean and mungbean.

Riverine nitrate and nitrification cannot be the only sources for nitrate assimilation in the Amazon River Plume margins

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract The Northern Amazon River Plume plays a crucial role in carbon sequestration and nitrogen cycling. This study quantified NO3− budgets along the plume during a period of high discharge, revealing NO3− uptake rates in excess of inputs from riverine sources and nitrification beyond 5°N.

Niche construction by non‐diazotrophs for N2 fixers in the eastern tropical North Atlantic Ocean

open access: yesGeophysical Research Letters, 2017
Diazotrophic dinitrogen (N2) fixation contributes ~76% to “new” nitrogen inputs to the sunlit open ocean, but environmental factors determining N2 fixation rates are not well constrained.

Di-nitrogen fixation at the early and late growth stages of soybean

open access: yesActa Scientiarum. Agronomy, 2018
  Soybean derives a significant portion of the required nitrogen (N) from the symbiosis with rhizobia bacteria. However, information on the available genetic variation for N2 fixation capacity in different growth stages of soybean is limited.

Nitrogen fixation and denitrification activity differ between coral- and algae-dominated Red Sea reefs

open access: yesScientific Reports, 2021
Coral reefs experience phase shifts from coral- to algae-dominated benthic communities, which could affect the interplay between processes introducing and removing bioavailable nitrogen.

Managing the Environmental Impacts of Outdoor Winter Grazing by Livestock

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 4, August 2026.
This review presents a synthesis of current knowledge about managing the potential impacts of outdoor animal wintering activities and their consequences for a range of environmental outcomes. The scope is confined to field‐based wintering approaches and thus, does not consider issues associated with the winter use of animal shelters or standoff systems.

A global dataset of nitrogen fixation rates across inland and coastal waters

open access: yesLimnology and Oceanography Letters
Biological nitrogen fixation is the conversion of dinitrogen (N2) gas into bioavailable nitrogen by microorganisms with consequences for primary production, ecosystem function, and global climate.
