Niche differentiation of microbial community shapes vertical distribution of recalcitrant dissolved organic matter in deep-sea sediments

Environment International, Journal Year: 2023, Volume and Issue: 178, P. 108080 - 108080

Published: July 1, 2023

Sedimentary organic matter provides carbon substrates and energy sources for microorganisms, which drive benthic biogeochemical processes in turn modify the quantity quality of dissolved (DOM). However, molecular composition distribution DOM its interactions with microbes deep-sea sediments remain poorly understood. Here, relationship were analyzed samples collected from two sediment cores (∼40 cm below sea floor), at depths 1157 2253 m South China Sea. Results show that niche differentiation was observed on a fine scale different layers, Proteobacteria Nitrososphaeria dominating shallow (0-6 cm) Chloroflexi Bathyarchaeia prevailing deeper (6-40 cm), indicating correspondence microbial community both geographical isolation availability matter. An intimate link between further indicates that, mineralization fresh layer potentially resulted accumulation recalcitrant (RDOM), while relatively low abundance RDOM linked to anaerobic utilization layers. In addition, higher overlying water, as compared surface sediment, suggests might be source RDOM. These results emphasize close relation community, laying foundation understanding complex dynamics water column.

Insights Into Phylogeny, Diversity and Functional Potential of Poseidoniales Viruses

Environmental Microbiology, Journal Year: 2025, Volume and Issue: 27(1)

Published: Jan. 1, 2025

ABSTRACT Viruses infecting archaea play significant ecological roles in marine ecosystems through host infection and lysis, yet they have remained an underexplored component of the virosphere. In this study, we recovered 451 archaeal viruses from a subtropical estuary, identifying 63 that are associated with dominant order Poseidoniales (Marine Group II Archaea). Phylogenetic analyses subset complete nearly‐complete viral genomes assigned these to Magrovirales , lineage viruses, identified novel group distinct . Utilising demarcation criteria established for classification tailed propose two families within Magrovirales: Apasviridae (magrovirus A), comprising genera Agnivirus Savitrvirus, Krittikaviridae E) encompassing genus Velanvirus. Additionally, new order, named Adrikavirales, which includes Vyasavirus. Our detailed genomic characterisation lineages revealed genes involved assembly egress, such as those responsible creating holin rafts lyse cell membranes, feature predominantly known bacteriophages. Furthermore, broad spectrum auxiliary metabolic genes, suggesting can modulate metabolism. Collectively, our findings substantially enhance current understanding diversity functional potential viruses.

Sulfate and Dissolved Organic Carbon Concentrations Drive Distinct Microbial Community Patterns in Prairie Wetland Ponds

Environmental Microbiology Reports, Journal Year: 2025, Volume and Issue: 17(1)

Published: Jan. 27, 2025

ABSTRACT Prairie wetland ponds on the Great Plains of North America offer a diverse array geochemical scenarios that can be informative about their impact microbial communities. These ecosystems invaluable ecological services while experiencing significant stressors, primarily through drainage and climate change. In this first study systematically combining environmental conditions with community composition to identify various niches in prairie ponds, sediments had higher abundance but lower phylogenetic diversity concentrations dissolved organic carbon ([DOC]; 10–18 mg/L) sulfate ([SO 4 2− ]; 37–58 water. As [DOC] [SO ] increased, there was an initial decline not diversity. Maximum values both occurred between 56 115 mg/L 5,000–6,000 decreased thereafter 150–180 8,000–14,000 ], respectively. findings confirm variables shape communities key taxa involved sulfur cycling dominated these potentially impacting vital biogeochemical processes such as bioavailability heavy metals, sequestration, methane emissions.

Abstract Coastal wetland sediments are vital to the global carbon cycle as they represent large sinks of blue – from atmospheric and oceanic sources which threatened by ecosystem loss. The forms sequestered sequestration capability affected many bio- geochemical factors that change unpredictably along coastal locales. In present study, we investigated three unique sites a mangrove two sabkhas with contrasting geology tidal influence in Qatar peninsula for their capture ability determine how biogeochemical indices affect potential. We applied suite biological tools, collecting sediment cores approximately 40 cm depth; analysed porewater; performed depth-profiling organic matter, sedimentary minerals, microbial community analysis surface pH, oxygen (O 2 ); redox potential hydrogen sulfide (H S) microsensors. High-resolution transmission electron microscopy energy-dispersive X-ray spectroscopy (TEM-EDXS) scanning (STXM) revealed templating effects promoted Mg-carbonate nucleation hypersaline environments. Microsensing reveals intricacy oxic/anoxic transition at surface. Microbial DNA sequencing various depths shows occurrence genera, whose functions explain trends pathways observed each site. Notably, found carbonate-sand sabkha was correlated matter degradation inorganic content, while siliciclastic it solely influenced density depth.

Over the last two decades archaeal research has expanded into a wide-ranging field, driven by fairly small community. Archaea are now recognized as important players in One-Health approach and expertise on biology of archaea become crucial study broad range topics environments, including host-associated microbiomes, major nutrient cycles, greenhouse gas metabolism, cell origin eukaryotes, adaptation life to extremes, well various biotechnological applications. Here, we summarize existing resources ongoing efforts engaged broader scientific community accelerate resource sharing guided FAIR (findable, accessible, interoperable, reusable) data-sharing principles. We highlight that: (i) aim share protocols best practices for working with (e.g. ARCHAEA.bio), (ii) combine large 'omics datasets dissemination unified, system-wide results Archaeal Proteome Project, KBase) (iii) provide opportunities scientists present their work supportive environment forge connections collaborations Power Hour).
