Drivers of pelagic and benthic microbial communities on Central Arctic seamounts

Frontiers in Marine Science, 2023
Seamounts are abundant features on the seafloor that serve as hotspots and barriers for the dispersal of benthic organisms. The primary focus of seamount ecology has typically been on the composition and distribution of faunal communities, with far less ...

Assessment of prokaryotic communities in Southwestern Atlantic deep-sea sediments reveals prevalent methanol-oxidising Methylomirabilales

Scientific Reports, 2023
Continental slopes can play a significant contribution to marine productivity and carbon cycling. These regions can harbour distinct geological features, such as salt diapirs and pockmarks, in which their depressions may serve as natural sediment traps ...

The Shift of Soil Bacterial Community After Afforestation Influence Soil Organic Carbon and Aggregate Stability in Karst Region

Frontiers in Microbiology, 2022
Soil microbes regulate the carbon cycle and affect the formation and stabilization of soil aggregates. However, the interactions between the soil microbial community and soil organic carbon (SOC) fractions, organic carbon (OC) content in aggregates, and ...

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).

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 ...

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,

Experimental, Genomic, and Structural Evidence Supporting Putative PET‐Hydrolases in Thermophilic Bacteria Isolated From Hot Springs in Cajamarca, Peru

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Integrated microbiological, genomic, and structural analyses of bacteria isolated from a Peruvian geothermal system reveal enzymatic potential for the transformation of polyesters such as PET. This study links experimental evidence with genomic determinants and in silico analyses that support the thermophilic bacteria biodegradation capacity.

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
