Microbial community changes along the active seepage site of one cold seep in the Red Sea

Frontiers in Microbiology, 2015
The active seepage of the marine cold seeps could be a critical process for the exchange of energy between the submerged geosphere and the sea floor environment through organic-rich fluids, potentially even affecting surrounding microbial habitats ...

Linking NrfD/PsrC‐like architecture to energy conservation: Functional residues in the quinone reactive QrcABCD complex of sulfate‐reducing bacteria

Protein Science, Volume 35, Issue 5, May 2026.
Abstract The QrcABCD quinone reductase complex is an electrogenic complex present in sulfate‐reducing bacteria of the Desulfobacterota phylum. It operates as a cytochrome c3:menaquinone oxidoreductase involved in electron transfer from periplasmic hydrogen or formate oxidation to the menaquinone (MK) pool.

Tropical aquatic Archaea show environment-specific community composition.

PLoS ONE, 2013
The Archaea domain is ubiquitously distributed and extremely diverse, however, environmental factors that shape archaeal community structure are not well known.

Hydromagnesite Precipitation in an Ultramafic‐Hosted Alkaline Lake: Insights From Lake Salda for Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Lake Salda (SW Turkey) is one of the most compelling terrestrial analogs for Jezero Crater on Mars due to its highly alkaline, Mg‐rich waters and hydromagnesite‐forming microbialites. This study integrates hydrochemical measurements, saturation‐index modeling, SEM–TEM imaging, and X‐ray diffraction (XRD) analysis to disentangle the biotic and ...

Ultrastructural insights into cellular organization, energy storage and ribosomal dynamics of an ammonia-oxidizing archaeon from oligotrophic oceans

Frontiers in Microbiology
IntroductionNitrososphaeria, formerly known as Thaumarchaeota, constitute a diverse and widespread group of ammonia-oxidizing archaea (AOA) inhabiting ubiquitously in marine and terrestrial environments, playing a pivotal role in global nitrogen cycling.

Characterisation of a cold‐adapted, thermostable glucokinase from psychrophilic Pseudoalteromonas sp. AS‐131 reveals how the enzyme achieves high thermal stability without loss of cold adaptation

The FEBS Journal, Volume 293, Issue 9, Page 2617-2636, May 2026.
We investigated glucokinase from the psychrophilic Pseudoalteromonas sp. AS‐131 (PsGK), which was isolated from the Antarctic Ocean. Biochemical studies revealed that PsGK is a cold‐adapted enzyme with high thermal stability, in contrast to general cold‐adapted enzymes, which have low thermal stability.

Membrane Vesicle Formation Removes Iron Sulfide Mineral Crusts From the Cell Surface of Growing Sulfate‐Reducing Bacteria

Geobiology, Volume 24, Issue 3, May/June 2026.
ABSTRACT Sulfate‐reducing bacteria (SRB) drive the process of sulfate reduction in low‐temperature sedimentary environments. Through the production of sulfide, they promote the formation of iron‐sulfide (Fe‐S) minerals when Fe(II) is available. The negative charge of the cell surface of bacteria can promote the binding of Fe(II), leading to the ...

Genomes of Two New Ammonia-Oxidizing Archaea Enriched from Deep Marine Sediments

PLoS ONE, 2014
Ammonia-oxidizing archaea (AOA) are ubiquitous and abundant and contribute significantly to the carbon and nitrogen cycles in the ocean. In this study, we assembled AOA draft genomes from two deep marine sediments from Donghae, South Korea, and Svalbard, Arctic region, by sequencing the enriched metagenomes. Three major microorganism clusters belonging

Oxygen-driven divergence of marine group II archaea reflected by transitions of superoxide dismutases

Microbiology Spectrum
The superoxide anion radical (O2•−), the primary reactive oxygen species (ROS), is detrimental to cellular functions. Marine group II (MGII) archaea predominantly inhabit surface ocean environments that are rich in ROS; however, their defense mechanisms ...
