Microbial communities reveal niche partitioning across the slope and bottom zones of the challenger deep. [PDF]

Environ Microbiol Rep
The physical–chemical characteristics related to depth across the slope and bottom, along with the distinct hydrology between seawaters and sediments, influence the microbial communities in the challenger deep of the Marianas trench. This leads to niche differentiation in community composition and metabolic functions, which is a result of niche ...

Deciphering Historical Water-Quality Changes Recorded in Sediments Using eDNA

Frontiers in Environmental Science, 2021
Reservoir sediments harbor abundant bacterial communities that are sensitive to substances transferred from the water column and might record historic water quality in environmental DNA (eDNA).

Novel Chloroflexi genomes from the deepest ocean reveal metabolic strategies for the adaptation to deep-sea habitats

Microbiome, 2022
Background The deep sea harbors the majority of the microbial biomass in the ocean and is a key site for organic matter (OM) remineralization and storage in the biosphere.

Homoacetogenesis in Deep-Sea Chloroflexi, as Inferred by Single-Cell Genomics, Provides a Link to Reductive Dehalogenation in Terrestrial Dehalococcoidetes

mBio, 2017
The deep marine subsurface is one of the largest unexplored biospheres on Earth and is widely inhabited by members of the phylum Chloroflexi. In this report, we investigated genomes of single cells obtained from deep-sea sediments of the Peruvian Margin,

A Seasonal Record of Bacterial Communities in Micritized Carbonate Sediments of the Eastern Red Sea

Environmental Microbiology, Volume 28, Issue 5, May 2026.
Evidence of intense micritization is observed throughout Al Kharrar lagoon sediments (0–80 cm). Diverse bacterial communities with putative roles in carbonate cycling display depth‐related shifts. Their stable seasonal presence suggests sustained micritization beyond the photic zone, refining our understanding of the potential role of bacteria in early

Sediment Depth-Dependent Spatial Variations of Bacterial Communities in Mud Deposits of the Eastern China Marginal Seas

Frontiers in Microbiology, 2018
The mud sediments of the eastern China marginal seas (ECMS) are deposited under different hydrodynamic conditions with different organic matter sources.

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 ...

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.

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.
