Methodological approaches to planning remediation actions on military territories contaminated with petroleum products

open access: yesМінеральні ресурси України, 2023
This paper describes the urgent problem of remediation of the subsurface contaminated with petroleum products. A strategy for the control of petroleum contamination of the subsurface, which should be based on risk assessment and management, is proposed ...

Visualizing Microorganism-Mineral Interaction in the Iberian Pyrite Belt Subsurface: The Acidovorax Case

open access: yesFrontiers in Microbiology, 2020
Despite being considered an extreme environment, several studies have shown that life in the deep subsurface is abundant and diverse. Microorganisms inhabiting these systems live within the rock pores and, therefore, the geochemical and geohydrological ...

Parapatric speciation of Meiothermus in serpentinite-hosted aquifers in Oman

open access: yesFrontiers in Microbiology, 2023
The factors that control the distribution and evolution of microbial life in subsurface environments remain enigmatic due to challenges associated with sampling fluids from discrete depth intervals via boreholes while avoiding mixing of fluids.

Viruses in Subsurface Environments

open access: yesAnnual Review of Virology, 2022
Over the past 20 years, our knowledge of virus diversity and abundance in subsurface environments has expanded dramatically through application of quantitative metagenomic approaches. In most subsurface environments, viral diversity and abundance rival viral diversity and abundance observed in surface environments.

Characterizing Natural Organic Matter Transformations by Microbial Communities in Terrestrial Subsurface Ecosystems: A Critical Review of Analytical Techniques and Challenges

open access: yesFrontiers in Microbiology, 2022
Determining the mechanisms, traits, and pathways that regulate microbial transformation of natural organic matter (NOM) is critical to informing our understanding of the microbial impacts on the global carbon cycle.

Bacterial Necromass Is Rapidly Metabolized by Heterotrophic Bacteria and Supports Multiple Trophic Levels of the Groundwater Microbiome

open access: yesMicrobiology Spectrum, 2022
Pristine groundwater is a highly stable environment with microbes adapted to dark, oligotrophic conditions. Input events like heavy rainfalls can introduce the excess particulate organic matter, including surface-derived microorganisms, thereby ...

Chapter 2: Digital Data Supplements subsurface dataset Rhine-Meuse delta in the Netherlands

open access: yes, 2023
Quantitative local determination of these characteristics poses a major challenge in natural environments with a heterogeneous substrate. Geological knowledge on the natural genesis and resulting structure of the subsurface may provide useful information

Ecohydrologically important subsurface structures in peatlands revealed by ground-penetrating radar and complex conductivity surveys. [PDF]

open access: yes, 2008
The surface pattern of vegetation influences the composition and humification of peat laid down during the development of a bog, producing a subsurface hydrological structure that is expected to affect both the rate and pattern of water flow.

Origin and Evolution of Flavin-Based Electron Bifurcating Enzymes

open access: yesFrontiers in Microbiology, 2018
Twelve evolutionarily unrelated oxidoreductases form enzyme complexes that catalyze the simultaneous coupling of exergonic and endergonic oxidation–reduction reactions to circumvent thermodynamic barriers and minimize free energy loss in a process known ...
