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 ...

Sulfur metabolizing microbes dominate microbial communities in Andesite-hosted shallow-sea hydrothermal systems.

PLoS ONE, 2012
To determine microbial community composition, community spatial structure and possible key microbial processes in the shallow-sea hydrothermal vent systems off NE Taiwan's coast, we examined the bacterial and archaeal communities of four samples ...

Response to Nutrient Stress in the Industrial Model Bacterium Cupriavidus necator: A Thermal Proteome Profiling (TPP) Investigation

PROTEOMICS, Volume 25, Issue 20, Page 25-38, October 2025.
ABSTRACT The facultative chemolithoautotroph Cupriavidus necator is capable of heterotrophic growth on diverse carbon sources, or of autotrophic growth using CO2 fixation with H2 as an energy source. Under stress conditions, it produces biodegradable polyesters (polyhydroxyalkanoates, PHAs) as a storage material occupying a high proportion of the total

Microbial diversity in the deep-subsurface hydrothermal aquifer feeding the giant gypsum crystal-bearing Naica mine, Mexico

Frontiers in Microbiology, 2013
The Naica mine in Northern Mexico is famous for its giant gypsum crystals, which may reach up to 11 m long and contain fluid inclusions that might have captured microorganisms during their formation.

Genomic resolution of a cold subsurface aquifer community provides metabolic insights for novel microbes adapted to high CO2 concentrations. [PDF]

, 2016
As in many deep underground environments, the microbial communities in subsurface high-CO2 ecosystems remain relatively unexplored. Recent investigations based on single-gene assays revealed a remarkable variety of organisms from little studied phyla in ...

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

Diversity and Transcriptional Levels of RuBisCO Form II of Sulfur-Oxidizing γ-Proteobacteria in Coastal-Upwelling Waters with Seasonal Anoxia

Frontiers in Marine Science, 2017
Seasonal wind-driven upwelling, high primary production in surface waters, and oxygen deficiency in subsurface waters characterize the coastal ecosystem of the subtropical eastern South Pacific (ESP), and shape the nature and dynamics of the microbial ...

Disproportionation of Inorganic Sulfur Compounds by Mesophilic Chemolithoautotrophic Campylobacterota

mSystems, 2023
The disproportionation of inorganic sulfur compounds could be widespread in natural habitats, and microorganisms could produce energy to support primary productivity through this catabolism. However, the microorganisms that carry this process out and the
