Evaluating Performance of Bouteloua gracilis Cultivars After Drought: The Role of the Soil Microbiome

Grass and Forage Science, Volume 80, Issue 4, December 2025.
ABSTRACT After the Dust Bowl in the 1930s, it was common to reseed native grasses in areas impacted by the drought to help restore grassland ecosystem structure and function. Given the forecasts of intensified drought events, reseeding may need to be employed more frequently to enhance post‐drought recovery. For such reseeding efforts, it is imperative

Genome-Enabled Insights into the Ecophysiology of the Comammox Bacterium “Candidatus Nitrospira nitrosa”

mSystems, 2017
The recently discovered comammox bacteria have the potential to completely oxidize ammonia to nitrate. These microorganisms are part of the Nitrospira genus and are present in a variety of environments, including biological nutrient removal (BNR) systems.

Heterotrophic ammonia oxidation by Alcaligenes balances ROS generation and terminal electron transport

mLife, Volume 4, Issue 5, Page 527-538, October 2025.
Abstract Heterotrophic nitrifiers are bacteria that aerobically oxidize ammonia in the presence of organic carbon sources, which differs from autotrophic nitrifiers that extract energy from ammonia oxidation for cell metabolism and growth. The physiological significance of heterotrophic ammonia oxidation remains unclear, even though this process has ...

It Takes a Village: Discovering and Isolating the Nitrifiers

Frontiers in Microbiology, 2020
It has been almost 150 years since Jean-Jacques Schloesing and Achille Müntz discovered that the process of nitrification, the oxidation of ammonium to nitrate, is a biological process carried out by microorganisms.

Substrate Effect on the Contribution of Ammonium and Urea to Marine Nitrification and Nitrous Oxide Production

Environmental Microbiology, Volume 27, Issue 10, October 2025.
The urea to ammonium concentration ratio is a good predictor of the relative importance of urea and ammonium to nitrite and N2O production in the ocean. In addition, the urea to ammonium ratio may be a key factor in shaping the genetic capability of marine ammonia‐oxidising archaea for urea utilisation.

Subsoiling Combined With Winter Active Italian Ryegrass Can Reduce Nitrous Oxide Emissions Without Increasing Nitrate Leaching: Evidence From Lysimeter and Field Plot Trials

Soil Use and Management, Volume 41, Issue 4, October‐December 2025.
ABSTRACT Subsoiling is a common practice for improving soil structure and has recently been recognised for its potential to reduce nitrous oxide (N2O) emissions. However, its impact on nitrate (NO3−–N) leaching must also be considered if it is to be used as a mitigation strategy. This study investigated N2O emissions, NO3−–N leaching and grass yield in

Media Optimization, Strain Compatibility, and Low-Shear Modeled Microgravity Exposure of Synthetic Microbial Communities for Urine Nitrification in Regenerative Life-Support Systems

, 2019
Urine is a major waste product of human metabolism and contains essential macro- and micronutrients to produce edible microorganisms and crops. Its biological conversion into a stable form can be obtained through urea hydrolysis, subsequent nitrification,

Niche differentiation and symbiotic association among ammonia/nitrite oxidizers in a full-scale rotating biological contactor

, 2022
Although the distribution of ammonia/nitrite oxidizers had been profiled in different habitats, current understanding is still limited regarding their niche differentiation in the integrated biofilm reactors, the symbiotic associations of ammonia/nitrite

Investigating the Atmospheric Microbial Ecosystem Through Theory, Bioenergetics, and Numerical Modeling: A Breath of Fresh Air for Aeromicrobiology

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 8, August 2025.
Abstract The atmosphere may constitute the Earth's largest microbial ecosystem, yet it remains the least understood. While microorganisms can persist and may even thrive in the polyextremes of the Earth's atmosphere, it is still unknown whether the atmosphere sustains an active microbial community.
