Groundwater Microbial Diversity Associated With Icelandic Basaltic Subsurface Environments

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Overview of microbial diversity and environmental drivers in Icelandic deep basaltic aquifers. Using 16S rRNA gene metabarcoding across 22 geothermal wells spanning broad temperature, pH, and bedrock‐age gradients, the study reveals distinct bacterial and archaeal community structures shaped by temperature, pH, and host‐rock reactivity.

Current understanding of electroautotrophy and its relevance in astrobiology‐related research

mLife, Volume 4, Issue 5, Page 473-493, October 2025.
Abstract Electroautotrophy—the use of extracellular electrons as the primary energy source for autotrophic metabolism—remains understudied compared to photoautotrophy and chemoautotrophy. Its occurrence in deep‐earth and deep‐sea environments suggests profound implications for astrobiology, yet electroautotrophic microorganisms remain poorly explored ...

Complete genome sequence of the sulfur-oxidizing chemolithoautotrophic Sulfurovum lithotrophicum 42BKTT

Standards in Genomic Sciences, 2017
A sulfur-oxidizing chemolithoautotrophic bacterium, Sulfurovum lithotrophicum 42BKTT, isolated from hydrothermal sediments in Okinawa, Japan, has been used industrially for CO2 bio-mitigation owing to its ability to convert CO2 into C5H8NO4 − at a high ...

The relationship between microbial community succession, decay, and anatomical character loss in non‐biomineralized animals

Palaeontology, Volume 68, Issue 5, September/October 2025.
Abstract A fundamental assumption of hypothesis‐driven decay experiments is that, during decay, the loss of anatomy follows a sequence broadly controlled by the intrinsic compositional properties of tissues. Recent work investigating the succession of postmortem endogenous microbial communities (thanatomicrobiome) challenges this assumption in that the

Mechanisms of Bacterial Extracellular Electron Exchange. [PDF]

, 2016
The biochemical mechanisms by which microbes interact with extracellular soluble metal ions and insoluble redox-active minerals have been the focus of intense research over the last three decades. The process presents two challenges to the microorganism;

Genomic Insights Into Energy Metabolism of Carboxydocella thermautotrophica Coupling Hydrogenogenic CO Oxidation With the Reduction of Fe(III) Minerals

Frontiers in Microbiology, 2018
The genus Carboxydocella forms a deeply branching family in the class Clostridia and is currently represented by three physiologically diverse species of thermophilic prokaryotes. The type strain of the type species, Carboxydocella thermautotrophica 41T,

Unusual Plastoquinones in Non‐Phototrophic Nitrifying Bacteria

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
Chemolithoautotrophic nitrifying bacteria of the genus Nitrospira exclusively possess unusual methyl‐plastoquinones with a standard redox potential below that of canonical plastoquinone and ubiquinone, suggesting functional roles in bidirectional electron transport.
