Effects of straw returning combined with earthworm addition on nitrification and ammonia oxidizers in paddy soil

Frontiers in Microbiology, 2022
IntroductionSoil ammonia oxidation, which acts as the first and rate-limiting step of nitrification, is driven by ammonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA) and complete ammonia oxidizer (comammox, amoA gene of clade-A and clade-B).

Comammox Nitrospira Clade B is the most abundant complete ammonia oxidizer in a dairy pasture soil and inhibited by dicyandiamide and high ammonium concentrations [PDF]

, 2022
The recent discovery of comammox Nitrospira, a complete ammonia oxidizer, capable of completing the nitrification on their own has presented tremendous challenges to our understanding of the nitrification process.

Genome-centered metagenomics illuminates adaptations of core members to a partial Nitritation–Anammox bioreactor under periodic microaeration

Frontiers in Microbiology, 2023
The partial nitritation-anaerobic ammonium oxidation (anammox; PN-A) process has been considered a sustainable method for wastewater ammonium removal, with recent attempts to treat low-strength wastewater.

Impact of comammox process on membrane-aerated biofilm reactor for autotrophic nitrogen removal

Water Research X
This study compared the simulation results of the side-stream membrane-aerated biofilm reactor (MABR) in terms of total nitrogen (TN) removal and N2O production obtained by the conventional comammox-exclusive biological nitrogen removal (BNR) model and ...

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.

Hydrological and microbial dynamics in an Arctic wastewater infiltration system

Vadose Zone Journal, Volume 25, Issue 2, March/April 2026.
Abstract Passive wastewater treatment systems are widely used in the Arctic, but studies addressing the vadose zone dynamics that influence the operation and performance of subsurface or soil‐based infiltration systems, such as rapid infiltration basins, are rare.

Acidification Stimulates N2O Production by Oceanic Nitrifying Bacteria

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Recent studies have shown changes in the production rates of nitrous oxide (N2O) in aerobic seawater in response to ocean acidification (OA). Understanding how N2O production responds to OA is crucial because N2O is a strong greenhouse gas and stratospheric ozone‐depleting substance emitted from the ocean.

Unveiling Global Diversity of Patescibacteriota and Functional Interactions with Host Microbes

Advanced Science, Volume 13, Issue 11, 23 February 2026.
Patescibacteriota represents a diverse group of ultra‐small epibiotic bacteria, which is largely overlooked. By integrating ribosomal protein S3‐based community profiling with MAG‐based metabolic potential analyses, this study provides new insights into their distribution, diversity, and potential interactions with other bacteria across diverse ...
