AmoA-Targeted Polymerase Chain Reaction Primers for the Specific Detection and Quantification of Comammox Nitrospira in the Environment

Frontiers in Microbiology, 2017
Nitrification, the oxidation of ammonia via nitrite to nitrate, has always been considered to be catalyzed by the concerted activity of ammonia- and nitrite-oxidizing microorganisms.

Long‐Term Low‐DO Operation Changes the Ammonia Oxidizer Community and Oxygen Kinetics

Water Environment Research, Volume 98, Issue 10, October 2026.
Lower dissolved oxygen reduces energy demand for wastewater treatment but slows ammonia removal. This study investigates a pilot process maintaining complete nitrification, documenting ammonia oxidizer adaptation to low dissolved oxygen. ABSTRACT Low–dissolved oxygen (DO) biological nutrient removal is an attractive option for energy and cost reduction,

Restoring soil health from dredged sediments through electrokinetic remediation for zucchini cultivation

Agronomy Journal, Volume 118, Issue 5, September/October 2026.
Abstract Dredged sediments are rich in organic matter and nutrients, but their agricultural reuse is limited by high salinity. Electrokinetic remediation (EKR) can remove salts, yet its effect on overall soil health, including microbial function and plant nutrient dynamics, remains poorly understood.

Abundance and Community Composition of Ammonia-Oxidizers in Paddy Soil at Different Nitrogen Fertilizer Rates

Journal of Integrative Agriculture, 2014
Ammonia oxidation, the first and rate-limiting step of nitrification, is carried out by both ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA).

Nitrogen and Phosphorus Fertilization Reshapes the Abundance and Structure of Ammonia Oxidizers on a Leymus chinensis Steppe in Northern China

Agronomy, 2022
Although nitrogen (N) and phosphorus (P) fertilization are important for maintaining the health and productivity of Leymus chinensis steppe, their impact on the abundance and community structure of ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing ...

Organ Size and Metabolic Rate Co‐Vary with Dimensions of the Obstetric Pelvis: The Metabolic Coordination of Childbirth Hypothesis

American Journal of Biological Anthropology, Volume 191, Issue 1, September 2026.
Among South Asian women, those with larger organ mass and energy expenditure, indicating greater capacity to promote fetal growth, had larger pelvic dimensions, partly explained by linear growth patterns. However, body fat correlated with energy expenditure but not pelvic dimensions, helping explain why high adiposity increases risk of obstructed ...

Variation in soil nitrous oxide emission with nitrogen application rates under reclaimed water irrigation

Frontiers in Environmental Science
Nitrous oxide (N2O) is a potent greenhouse gas primarily emitted from agricultural soils through microbial nitrogen transformation processes. Different nitrogen application rates and fertilizer types influence soil nitrogen transformation pathways ...

Effects of mowing dominant grasses on root exudation and soil nitrogen cycling in a natural sod culture apple orchard

Plant, Soil and Environment, 2021
We evaluated the effects of mowing dominant grasses on root exudation and soil nitrogen (N) cycling by assessing metabolomics analysis of root exudates, microbial metabolism, the abundance of N-cycling-related prokaryotes, and different forms of N ...

Microbiome‐mediated plant‐soil feedbacks as a tool for resilient agriculture

iMetaOmics, Volume 3, Issue 3, September 2026.
Translating plant‐soil feedbacks (PSFs) into reliable agricultural management requires shifting from input‐dependent practices toward endogenous, process‐driven crop resilience. To bridge this gap, we propose a predictive framework centered on three strategic interventions: engineering the crop holobiont, diversifying the soil habitat, and deploying ...

Warm‐wet transition restructures arid lake microbiomes and functional potential

iMetaOmics, Volume 3, Issue 3, September 2026.
This study summarizes how a long‐term warm‐dry to warm‐wet transition restructures microbiomes and functional potential in Lake Bosten, an arid lake in northwestern China. Warm‐wet hydroclimatic change increased water level and hydrological connectivity, while decreasing salinity and total nitrogen.
