Energy Gradients Structure Microbial Communities Across Sediment Horizons in Deep Marine Sediments of the South China Sea

Frontiers in Microbiology, 2018
The deep marine subsurface is a heterogeneous environment in which the assembly of microbial communities is thought to be controlled by a combination of organic matter deposition, electron acceptor availability, and sedimentology.

Effect of irrigation and drainage practices on soil microbial community composition and physicochemical properties in typical saline–alkaline soil

Vadose Zone Journal, Volume 25, Issue 1, January/February 2026.
Abstract Irrigation and subsurface drainage (ISD) is used to improve physicochemical properties of soil; however, its effects on soil microorganism characteristics are not well understood, particularly in saline–alkaline soils. In this study, a 1‐year (2023–2024) field experiment was conducted in the Inner Mongolia to assess the effects of three ISD ...

Impact of Anaerobic Cold Storage on Subseafloor Microbial Communities

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Sediment cores recovered from the deep sea often cannot be sampled for microbiological analysis immediately due to the need for core splitting and processing for subsequent onboard measurements and core storage. Consequently, sections are often stored at 4°C under anaerobic conditions for extended periods.

Decoding Past Microbial Communities Shifts Induced by Natural and Anthropogenic Disturbance Events Through Extracellular DNA

Molecular Ecology, Volume 34, Issue 20, October 2025.
ABSTRACT Coastal marine ecosystems face escalating threats from multiple anthropogenic stressors, including the release of industrial contaminants. Despite decades of industrial activity impacting marine ecosystems, long‐term effects on microbial communities and related key ecological functions remain unclear.

Diversity of Rare and Abundant Prokaryotic Phylotypes in the Prony Hydrothermal Field and Comparison with Other Serpentinite-Hosted Ecosystems

Frontiers in Microbiology, 2018
The Bay of Prony, South of New Caledonia, represents a unique serpentinite-hosted hydrothermal field due to its coastal situation. It harbors both submarine and intertidal active sites, discharging hydrogen- and methane-rich alkaline fluids of low ...

Biogeochemical characterization of micritized carbonate grains in the shallow‐marine Al‐Kharrar Lagoon (Red Sea, Saudi Arabia)

Sedimentology, Volume 72, Issue 5, Page 1593-1619, August 2025.
ABSTRACT Micritization of marine carbonate grains is an early diagenetic process involving the alteration of the original carbonate fabric and the formation of cryptocrystalline textures through cycles of dissolution and reprecipitation. Microorganisms play a significant role in this process, actively contributing to the formation of constructive and ...

Probe Capture Enrichment Sequencing of amoA Genes Improves the Detection of Diverse Ammonia‐Oxidising Archaeal and Bacterial Populations

Molecular Ecology Resources, Volume 25, Issue 3, April 2025.
ABSTRACT The ammonia monooxygenase subunit A (amoA) gene has been used to investigate the phylogenetic diversity, spatial distribution and activity of ammonia‐oxidising archaeal (AOA) and bacterial (AOB), which contribute significantly to the nitrogen cycle in various ecosystems. Amplicon sequencing of amoA is a widely used method; however, it produces

Discovering Hidden Archaeal and Bacterial Lipid Producers in a Euxinic Marine System

Environmental Microbiology, Volume 27, Issue 3, March 2025.
We investigated the bacterial and archaeal membrane lipids in the Black Sea, focusing on isoprenoidal and branched GDGTs, combining high‐resolution accurate mass/mass spectrometry with metagenomics. Our objective was to identify the potential biological producers of these lipids and to begin understanding their role in microbial adaptation.

Comparative genomics reveals Dehalogenimonas genome dynamics and evolutionary trajectories toward organohalide respiration

Applied and Environmental Microbiology
Dehalogenimonas spp. specialize in organohalide respiration, a metabolism that features reductive dehalogenase (RDase) as the key catalyst, yet their evolutionary history and adaptation to halogenated substrates are largely unknown. Here, we surveyed the
