Active sulfur cycling in the terrestrial deep subsurface. [PDF]

ISME J, 2020
AbstractThe deep terrestrial subsurface remains an environment where there is limited understanding of the extant microbial metabolisms. At Olkiluoto, Finland, a deep geological repository is under construction for the final storage of spent nuclear fuel.

Sustainable co-production of 1,3-PDO, ethanol and H2 from glycerol via dark fermentation by Citrobacter telavivensis T1.2D-1 isolated from the deep subsurface [PDF]

Frontiers in Bioengineering and Biotechnology
The increasing production of biodiesel has led to a surplus of glycerol, a polluting by-product in need of valorization. In this study, we demonstrate that Citrobacter telavivensis T1.2D-1, an extremophile bacterium isolated from the Iberian Pyrite Belt,

Establishment of the Deep Mine Microbial Observatory (DeMMO), South Dakota, USA, a Geochemically Stable Portal Into the Deep Subsurface

Frontiers in Earth Science, 2019
Identifying temporal trends in deep subsurface geomicrobiology is challenging as it requires both in-depth knowledge of in situ geochemistry and innovative sampling techniques.

Progress and prospect of surface-wave imaging techniques in near-surface applications

地球与行星物理论评, 2022
Elastic properties of near-surface materials and their effects on seismic wave propagation are of fundamental interest in groundwater, engineering, and environmental studies. Shear-wave velocity is used to determine 'stiffness', one of the key properties

A Comparative Study on the Dynamic Tensile Strength Evaluation Method of Rock Materials

Shock and Vibration, 2023
The representative calculation methods of dynamic tensile strength applied to the spalling test are comparatively reviewed in the same experimental cases. The results are compared with those of the ISRM suggested dynamic BD method.

Advances in Defining Ecosystem Functions of the Terrestrial Subsurface Biosphere

Frontiers in Microbiology, 2022
The subsurface is one of the last remaining ‘uncharted territories’ of Earth and is now accepted as a biosphere in its own right, at least as critical to Earth systems as the surface biosphere.
