Pleomorphic viruses establish stable relationship with marine hyperthermophilic archaea

The ISME Journal
Abstract Non-lytic viruses with enveloped pleomorphic virions (family Pleolipoviridae) are ubiquitous in hypersaline environments across the globe and are associated with nearly all major lineages of halophilic archaea. However, their existence in other ecosystems remains largely unknown. Here, we show that evolutionarily-related viruses

Transient Ecological Niches for Diazotrophs in Upwelling Bays

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Diazotrophs, microorganisms capable of fertilizing the ocean through biological nitrogen fixation (BNF), are widespread in the oceans, including upwelling bays. However, their ability to respond to short‐lived upwelling pulses, lasting only a few days, remains poorly understood. To investigate diazotrophy across temporal scales, we analyzed 18

Large-scale biogeography of marine pelagic bacteria and archaea

, 2023
The dark ocean contains about 70% of the ocean’s microbial cells and 60% of its heterotrophic activity, which is mainly fueled by the flux of organic particles produced in the surface ocean and exported to the bathypelagic ocean (1,000 – 4,000 m depth).

Tropical aquatic Archaea show environment-specific community composition.

PLoS ONE, 2013
The Archaea domain is ubiquitously distributed and extremely diverse, however, environmental factors that shape archaeal community structure are not well known.

Putative Mechanisms for Initial Reaction of Anaerobic Benzene Degradation Presumably Involving a Flavoprotein

Environmental Microbiology, Volume 28, Issue 8, August 2026.
Anaerobic biodegradation of benzene by sulphate‐reducing strain BzS1 was studied by combining genomics, differential proteomics and targeted metabolite analyses. Strain BzS1 has an exceptionally streamlined metabolism. A highly abundant heterotrimeric flavoprotein may add benzene to either enolpyruvate or glutaconyl‐CoA followed by channelling into the

In Situ Bacterioplankton Growth Partitioning by High‐Resolution Metatranscriptomics

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Bacterial growth and primary production are key ecological indicators, yet often measured in bulk. Using metatranscriptomics, the authors identify FtsZ expression to track dividing cells (A, B). Phylogenetic placement of transcripts (C–E) enables linking growth activity to specific taxa (E, F), potentially bridging bulk measurements with fine‐scale ...

Three Decades of Soil N2O Research—Insights and Gaps

Global Change Biology, Volume 32, Issue 8, August 2026.
Progress in N2O Research and Key Breakthroughs and Transitions from 1990 to 2025 across three domains: (A) process understanding, (B) microbial ecology, and (C) modelling of soil N2O emissions. ABSTRACT Nitrous oxide (N2O) is a potent greenhouse gas (GHG) whose atmospheric concentration continues to rise, largely driven by nitrogen (N) inputs to ...

Ultrastructural insights into cellular organization, energy storage and ribosomal dynamics of an ammonia-oxidizing archaeon from oligotrophic oceans

Frontiers in Microbiology
IntroductionNitrososphaeria, formerly known as Thaumarchaeota, constitute a diverse and widespread group of ammonia-oxidizing archaea (AOA) inhabiting ubiquitously in marine and terrestrial environments, playing a pivotal role in global nitrogen cycling.

Substrate‐driven enrichment and eDNA metabarcoding reveal indigenous microbiomes in mangrove sediments with potential for ammonia and nitrite transformation

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract Effective management of ammonia and nitrite remains a major challenge in intensive shrimp aquaculture, where excessive nitrogen loading compromises water quality and animal health. Indigenous microbial communities inhabiting mangrove sediments are widely considered potential sources of ammonia‐ and nitrite‐transforming microorganisms; however,

Oxygen-driven divergence of marine group II archaea reflected by transitions of superoxide dismutases

Microbiology Spectrum
The superoxide anion radical (O2•−), the primary reactive oxygen species (ROS), is detrimental to cellular functions. Marine group II (MGII) archaea predominantly inhabit surface ocean environments that are rich in ROS; however, their defense mechanisms ...
