Evaluation of the process performance of comammox-like nitrospira dominant down-flow hanging sponge reactor with reduced nitrous oxide emissions

Water Research X
Nitrification/denitrification mitigates excess nitrogen in wastewater and reduces nutrient pollution in recipient surface waters but emits substantial amounts of nitrous oxide (N₂O).

Light-weight oxygen supply for portable biological nitrogen removal from urine and sweat

Chemical Engineering Journal Advances, 2022
The weight or availability of potable water often limits foot travel into remote arid regions for recreational, or government-sponsored activities. To address this limitation, a portable bioprocessing unit, intended to be one treatment stage in the ...

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.

Low yield and abiotic origin of N2O formed by the complete nitrifier Nitrospira inopinata

Nature Communications, 2019
Ammonia-oxidizing bacteria and archaea are major producers of the gases nitrous oxide and nitric oxide. Here, Kits et al. show that a complete ammonia-oxidizing (comammox) bacterium emits nitrous oxide at levels that are comparable to those produced by ...

Comparison of Biochar- and Lime-Adjusted pH Changes in N₂O Emissions and Associated Microbial Communities in a Tropical Tea Plantation Soil

Agronomy, 2023
The use of biochar and lime (CaO) is a common approach to mitigating soil acidification. However, little is known about how biochar and lime amendments impact N2O emissions and potential microbial mechanisms.

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.

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.
