Long solids retention times and attached growth phase favor prevalence of comammox bacteria in nitrogen removal systems [PDF]

Water Research, 2019
ABSTRACT The discovery of the complete ammonia oxidizing (comammox) bacteria overturns the traditional two-organism nitrification paradigm which largely underpins the design and operation of nitrogen removal during wastewater treatment.

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 ...

Compound drought-heat legacies promote the contribution of comammox Nitrospira to N2O emissions: as evidenced from both acidic and alkaline soils

Geoderma
The responses of complete ammonia oxidization (comammox) to compound drought and heat and their contributions to post-drought nitrous oxide (N2O) emissions remain unclear.

Principles for Rigorous Design and Application of Synthetic Microbial Communities

Advanced Science, Volume 13, Issue 10, 18 February 2026.
SynComs are artificially designed to enable inter‐species metabolic interactions, metabolic division of labor, and ecological interactions that can elicit phenotypes like colonization stability and environmental adaptation. This systematic review explores the processes used to construct SynComs, the assessment of the mechanisms of metabolic interaction

Spatial and Temporal Variability of Microbial Nitrogen Cycling Genes in Arctic Streams

Global Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract The Arctic is undergoing rapid climate change, with thawing permafrost and shifts in vegetation altering nitrogen (N) delivery into streams. These changes can significantly affect microbial biofilm diversity and functional roles, yet knowledge of streambed microbial biofilms remains scarce across the Arctic.

Plant Identity Impacts the Soil Microbiome More Than Interspecific Interactions in Intensively Managed Grasslands

European Journal of Soil Science, Volume 77, Issue 1, January–February 2026.
The impact of plant identity and interspecific interactions on the soil microbiome in intensively managaged grasslands. ABSTRACT Plants and soil microbes are intricately linked, and agricultural production relies heavily on microbially mediated ecosystem services. However, the effects of plant diversity (richness, relative abundance and composition) on

Soil pH modulates microbial nitrogen allocation in soil via compositional and metabolic shifts across forests in Japan

iMetaOmics, Volume 2, Issue 4, December 2025.
This study reveals how soil pH regulates microbial N allocation in forest soils across Japan. We show that microbial abundance controls the overall rate of N cycling, while microbial composition and metabolic potential determine whether ammonium is released or retained.

Enrichment of Comammox and Nitrite-Oxidizing Nitrospira From Acidic Soils

Frontiers in Microbiology, 2020
In agricultural soils fertilized with a high amount of ammonium nitrogen, the pH decreases because of the oxidation of ammonia by nitrifiers. Molecular-based analyses have revealed that members of the genus Nitrospira dominate over other nitrifiers in ...

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

Unique characteristics of acid-tolerant comammox bacteria revealed by multi-omics analyses

ISME Communications
Abstract Complete ammonia oxidation (comammox) is a critical biogeochemical process in the nitrogen cycle. In this study, we utilized comammox Nitrospira to convert urine wastewater into ammonium nitrate by operating a laboratory-scale membrane bioreactor at pH 3 ~ 4.
