Eutrophication-induced water deoxygenation occurs continually in coastal oceans, and alters community structure, metabolic processes, and the energy shunt, resulting in a major threat to the ecological environment.

Depth-related distribution of a key gene of the tetraether lipid biosynthetic pathway in marine Thaumarchaeota [PDF]
The distribution of isoprenoid glycerol dialkyl glycerol tetraethers (GDGT) lipids synthesized by Thaumarchaeota has been shown to be temperature-dependent in world oceans.

Low genome content diversity of marine planktonic Thaumarchaeota
Summary Members of Thaumarchaeota are responsible for much of the ammonia oxidation occurring in the ocean. Recent studies showed that marine Thaumarchaeota have versatile metabolic capabilities, but sequencing additional genomes has not significantly increased the gene content ascribed to this group.

Changes in DOM composition influence prokaryotic species growth in the Mediterranean Sea, shaping their metabolic responses and organic matter processing. In our study, higher DOP consumption and alkaline phosphatase activity led to the accumulation of recalcitrant DOM, highlighting how microbial community shifts drive distinct pathways in carbon ...

Ammonia-oxidising archaea living at low pH: Insights from comparative genomics [PDF]
Obligate acidophilic members of the thaumarchaeotal genus Candidatus Nitrosotalea play an important role in nitrification in acidic soils, but their evolutionary and physiological adaptations to acidic environments are still poorly understood, with only ...

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Diversity and seasonal dynamics of airborne archaea [PDF]
Archaea are widespread and abundant in many terrestrial and aquatic environments, and are thus outside extreme environments, accounting for up to ~10% of the prokaryotes.

Traditional 16S rRNA gene and Internal Transcribed Spacer region amplicon sequencing provides only relative abundance, often leading to biased ecological interpretations. To overcome this limitation, we developed Accu16S/AccuITS, an absolute quantification method for bacterial and fungal amplicons based on synthetic internal spike‐in DNA with known ...

Substrate pulses as a selection factor for clades of marine Thaumarchaeota
Abstract Oxidation rates of N supplied as ammonium (AO) or urea (UO) by Thaumarchaeota-dominated nitrifying communities in samples of aerobic waters from continental shelf and slope waters of the Southern Ocean west of the Antarctic Peninsula were inhibited by substrate amendments in the low nM range.
