Subsurface Microbial Community Composition in Anchialine Environments Is Influenced by Original Organic Carbon Source at Time of Deposition

Frontiers in Marine Science, 2022
Prokaryotes constitute the majority of sedimentary biomass, where they cycle organic carbon and regulate organic matter transformation. The microbes inhabiting sediment are diverse and the factors controlling microbial community composition are not fully

Organic Matter Type Defines the Composition of Active Microbial Communities Originating From Anoxic Baltic Sea Sediments

Frontiers in Microbiology, 2021
Carbon cycling in anoxic marine sediments is dependent on uncultured microbial communities. Niches of heterotrophic microorganisms are defined by organic matter (OM) type and the different phases in OM degradation.

High-throughput sequencing revealed novel Dehalococcoidia in dechlorinating microbial enrichments from PCB-contaminated marine sediments [PDF]

FEMS Microbiology Ecology, 2017
In this study, six PCE-to-ethene dechlorinating cultures, fed with a fermentable substrate (lactate) or hydrogen as electron donor, were obtained from PCB and PCE dechlorinating microcosms constructed with PCB-contaminated marine sediments. A novel Chloroflexi member (OTU-DIS1) affiliated to Dehalococcoidales Incertae Sedis, only distantly related to ...

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 ...

Decoding Past Microbial Communities Shifts Induced by Natural and Anthropogenic Disturbance Events Through Extracellular DNA. [PDF]

Mol Ecol
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.

Genome sequencing of a single cell of the widely distributed marine subsurface Dehalococcoidia, phylum Chloroflexi [PDF]

The ISME Journal, 2013
Abstract Bacteria of the class Dehalococcoidia (DEH), phylum Chloroflexi, are widely distributed in the marine subsurface, yet metabolic properties of the many uncultivated lineages are completely unknown. This study therefore analysed genomic content from a single DEH cell designated ‘DEH-J10’ obtained from the sediments of Aarhus Bay ...

Organic sulfur from source to sink in low‐sulfate Lake Superior

Limnology and Oceanography, Volume 68, Issue 12, Page 2716-2732, December 2023., 2023
Abstract Organic sulfur plays a crucial role in the biogeochemistry of aquatic sediments, especially in low sulfate (< 500 μM) environments like freshwater lakes and the Earth's early oceans. To better understand organic sulfur cycling in these systems, we followed organic sulfur in the sulfate‐poor (< 40 μM) iron‐rich (30–80 μM) sediments of Lake ...

Resilience and functional redundancy of methanogenic digestion microbiome safeguard recovery of methanogenesis activity under the stress induced by microplastics

mLife, Volume 2, Issue 4, Page 378-388, December 2023., 2023
Abstract Microplastics and nanoplastics are emerging pollutants that substantially influence biological element cycling in natural ecosystems. Plastics are also prevalent in sewage, and they accumulate in waste‐activated sludge (WAS). However, the impacts of plastics on the methanogenic digestion of WAS and the underpinning microbiome remain ...
