A global perspective on bacterial diversity in the terrestrial deep subsurface [PDF]

open access: yesMicrobiology (United Kingdom), 2023
While recent efforts to catalogue Earth’s microbial diversity have focused upon surface and marine habitats, 12–20% of Earth’s biomass is suggested to exist in the terrestrial deep subsurface, compared to ~1.8% in the deep subseafloor.

Shewanella sp. T2.3D-1.1 a Novel Microorganism Sustaining the Iron Cycle in the Deep Subsurface of the Iberian Pyrite Belt [PDF]

open access: yesMicroorganisms, 2022
The Iberian Pyrite Belt (IPB) is one of the largest deposits of sulphidic minerals on Earth. Río Tinto raises from its core, presenting low a pH and high metal concentration.

The Mystery of Piezophiles: Understudied Microorganisms from the Deep, Dark Subsurface

open access: yesMicroorganisms, 2023
Microorganisms that can withstand high pressure within an environment are termed piezophiles. These organisms are considered extremophiles and inhabit the deep marine or terrestrial subsurface.

The potential for coupled organic and inorganic sulfur cycles across the terrestrial deep subsurface biosphere [PDF]

open access: yesNature Communications
Organosulfur compounds (OrgS) are fundamental components of life’s biomass, yet the cycling of these compounds in the terrestrial deep subsurface, one of Earth’s largest ecosystems, has gone relatively unexplored.

Microbial Life in the Deep Subsurface Aquifer Illuminated by Metagenomics [PDF]

open access: yesFrontiers in Microbiology, 2020
To get insights into microbial diversity and biogeochemical processes in the terrestrial deep subsurface aquifer, we sequenced the metagenome of artesian water collected at a 2.8 km deep oil exploration borehole 5P in Western Siberia, Russia. We obtained

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]

open access: yesFrontiers 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,

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

open access: yes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

open access: yesShock 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.
