Oxidation of urea‐derived nitrogen by thaumarchaeota‐dominated marine nitrifying communities [PDF]

Environmental Microbiology, 2016
Summary Urea nitrogen has been proposed to contribute significantly to nitrification by marine thaumarchaeotes. These inferences are based on distributions of thaumarchaeote urease genes rather than activity measurements. We found that ammonia oxidation rates were always higher than oxidation rates of urea‐derived

Degradable versus inert microplastics: Effects on soil organic carbon persistence via microbial drivers in an agroecosystem

Functional Ecology, Volume 40, Issue 8, Page 2628-2641, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Microplastics (MPs) are widespread in terrestrial ecosystems, raising global concerns that they may disrupt soil organic carbon (SOC) cycling and undermine agroecosystem contributions to climate mitigation.

Archaeal Tetraether Lipids as Tracers for Past Marine Environmental Change

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract Archaea are single‐celled microorganisms that are abundant in marine environments and play a key role in the carbon and nitrogen cycles. Archaea can biosynthesize a wide variety of isoprenoid membrane lipids, including isoprenoid glycerol dibiphytanyl glycerol tetraethers (isoGDGTs).

Depth-related distribution of a key gene of the tetraether lipid biosynthetic pathway in marine Thaumarchaeota

, 2015
The distribution of isoprenoid glycerol dialkyl glycerol tetraethers (GDGT) lipids synthesized by Thaumarchaeota has been shown to be temperature-dependent in world oceans.

Linking Abundance and Activity of Ammonia‐Oxidising Bacteria and Archaea in an Agriculturally Impacted First‐Order Stream

Environmental Microbiology, Volume 28, Issue 7, July 2026.
Ammonia‐oxidising archaea (AOA) and bacteria (AOB) coexist in streambed sediments, but their contributions to nitrification remain unresolved. Using field sampling, sequencing, qPCR, microcosm incubations and modelling, we show that AOB dominated nitrification in streambed sediments despite lower abundance, emphasizing the importance of distinguishing ...

Microbial Diversity in a Venezuelan Orthoquartzite Cave is Dominated by the Chloroflexi (Class Ktedonobacterales) and Thaumarchaeota Group I.1c.

Frontiers in Microbiology, 2014
The majority of caves are formed within limestone rock and hence our understanding of cave microbiology comes from carbonate-buffered systems. In this paper, we describe the microbial diversity of Roraima Sur Cave, an orthoquartzite (SiO4) cave within ...

Functional Metagenomics Insights Into the Allium ampeloprasum Rhizosphere Microbiome Under Different Fertilization Regimes

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Shotgun metagenomic sequencing was used to characterize the functional potential of the Allium ampeloprasum rhizosphere microbiome under chemical fertilizer (G1), biofertilizer (G2), and unfertilized (Bulk) soil (G3) management practices. This study revealed that different fertilization regimes altered microbial functional profiles.
