Metagenomic Analysis of Thawing Permafrost Highlights Links Between Carbon and Nitrogen Cycling Processes in Abrupt Thaw Simulation

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Abrupt permafrost thaw events are projected to contribute up to 40% of permafrost carbon (C) release to the atmosphere. They involve sudden hydrological shifts within the soil column; however, the exact microbial functional pathway shifts induced by these events remain cryptic. To investigate how C and nutrient cycling processes differ in thaw

Nitrification and Nitrifying Bacteria in a Coastal Microbial Mat [PDF]

, 2015
The first step of nitrification, the oxidation of ammonia to nitrite, can be performed by ammonia-oxidizing archaea (AOA) or ammonium-oxidizing bacteria (AOB).

Hydrazine Synthase From Anammox Is Inhibited by Linear and Aromatic Alkynes

Environmental Microbiology, Volume 28, Issue 3, March 2026.
Linear and aromatic alkynes inhibit anammox in culture and in wetlands. The inhibition by alkynes is specific to the hydrazine synthase, a key enzyme in the anammox pathway. ABSTRACT N2O emissions by nitrifiers are often estimated using selective inhibitors, such as 1‐alkynes.

Metagenomic Analysis of Ammonia-Oxidizing Archaea Affiliated with the Soil Group [PDF]

Frontiers in Microbiology, 2012
Ammonia-oxidizing archaea (AOA) have recently been recognized as a significant component of many microbial communities and represent one of the most abundant prokaryotic groups in the biosphere. However, only few AOA have been successfully cultivated so far and information on the physiology and genomic content remains scarce.

Inhibition of Ammonia Monooxygenase from Ammonia-Oxidizing Archaea by Linear and Aromatic Alkynes

Applied and Environmental Microbiology, 2020
Archaeal and bacterial ammonia oxidizers (AOA and AOB, respectively) initiate nitrification by oxidizing ammonia to hydroxylamine, a reaction catalyzed by ammonia monooxygenase (AMO).

River Microbiomes as Sentinels of National‐Scale Freshwater Ecosystems

Global Change Biology, Volume 32, Issue 3, March 2026.
River biofilms are complex microbial assemblages that underpin aquatic food webs and play a central role in biogeochemical cycling. By responding to environmental signals over space and time, biofilm microbial communities can act as sensitive indicators of river health.

Ancestral reconstructions decipher major adaptations of ammonia oxidizing archaea upon radiation into moderate terrestrial and marine environments

bioRxiv, 2020
Unlike all other archaeal lineages, ammonia oxidizing archaea (AOA) of the phylum Thaumarchaea are widespread and abundant in all moderate and oxic environments on Earth. The evolutionary adaptations that led to such unprecedented ecological success of a

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
