Organic matter content and source is associated with the depth‐dependent distribution of prokaryotes in lake sediments

Freshwater Biology, Volume 69, Issue 4, Page 496-508, April 2024.
Abstract Aquatic sediments harbour a diverse array of microorganisms that drive organic matter recycling, carbon sequestration and greenhouse gases (e.g., CO2, CH4, N2O) emissions. Although largely studied in water columns, vertical profiles of the diversity and composition of prokaryotic communities (i.e., Bacteria and Archaea) in aquatic sediments ...

YeeD is an essential partner for YeeE-mediated thiosulfate uptake in bacteria and regulates thiosulfate ion decomposition.

PLoS Biology
Uptake of thiosulfate ions as an inorganic sulfur source from the environment is important for bacterial sulfur assimilation. Recently, a selective thiosulfate uptake pathway involving a membrane protein YeeE (TsuA) in Escherichia coli was characterized.

Similar diversity of Alphaproteobacteria and nitrogenase gene amplicons on two related Sphagnum mosses

Frontiers in Microbiology, 2012
Sphagnum mosses represent a main component in ombrotrophic wetlands. They harbor a specific and diverse microbial community with essential functions for the host. To understand extend and degree of host specificity, Sphagnum fallax and S.

Metabarcoding reveals unique microbial mat communities and evidence of biogeographic influence in low‐oxygen, high‐sulfur sinkholes and springs

Ecology and Evolution, Volume 14, Issue 3, March 2024.
Groundwater‐fed underwater sinkholes and springs create habitats with high‐sulfur, low‐oxygen conditions. Multi‐marker metabarcoding was used to describe microbial mat communities in these extreme aquatic habitats. Unique bacterial and diatom communities were found in five springs in Michigan and Florida, with water parameters and biogeography ...

PIP2 inhibits pore opening of the cyclic nucleotide-gated channel SthK

Nature Communications
The signaling lipid phosphatidylinositol-4,5-bisphosphate (PIP2) regulates many ion channels. It inhibits eukaryotic cyclic nucleotide-gated (CNG) channels while activating their relatives, the hyperpolarization-activated and cyclic nucleotide-modulated (

Coral-Associated Bacterial Diversity is Conserved Across Two Deep-Sea Anthothela Species

Frontiers in Microbiology, 2016
Cold-water corals, similar to tropical corals, contain diverse and complex microbial assemblages. These bacteria provide essential biological functions within coral holobionts, facilitating increased nutrient utilization and production of antimicrobial ...

Combined Genomic and Imaging Techniques Show Intense Arsenic Enrichment Caused by Detoxification in a Microbial Mat of the Dead Sea Shore

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 3, March 2024.
Abstract Microbial mats and microbialites are essential tools for reconstructing early life and its environments. To better understand microbial trace element cycling, a microbial mat was collected from the sinkhole systems of the western shores of the Dead Sea, a dynamic environment exhibiting diverse extreme environments.

Microbial Assemblages and Metabolic Activity in Organic‐Rich Subterranean Estuaries: Impact of Climate and Land Use Changes

Journal of Geophysical Research: Biogeosciences, Volume 129, Issue 3, March 2024.
Abstract Microbial communities in subterranean estuaries mediate biogeochemical reactions of coastal groundwater discharging into the oceans; however, studies on their response to abrupt environmental changes caused by climate and land use alterations are still limited.
