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

E3S Web of Conferences, 2016 Life extends far deeper into the Earth's subsurface than presumed possible 30 years ago. In the past, it was assumed that life is a surface phenomenon, and that even “hardy prokaryotic types” are not capable of living deeper than tens of meters below the

An Ionic Limit to Life in the Deep Subsurface. [PDF]
Front Microbiol, 2019 The physical and chemical factors that can limit or prevent microbial growth in the deep subsurface are not well defined. Brines from an evaporite sequence were sampled in the Boulby Mine, United Kingdom between 800 and 1300 m depth. Ionic, hydrogen and oxygen isotopic composition were used to identify two brine sources, an aquifer situated in strata ...

Evolutionary stasis of a deep subsurface microbial lineage. [PDF]
ISME J, 2021 Abstract Sulfate-reducing bacteria Candidatus Desulforudis audaxviator (CDA) were originally discovered in deep fracture fluids accessed via South African gold mines and have since been found in geographically widespread deep subsurface locations.

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

Artificial subsurface lithoautotrophic microbial ecosystems and gas storage in deep subsurface. [PDF]
FEMS Microbiol EcolAbstract Over the next few years, it is planned to convert all or part of the underground gas storage (UGS) facilities used for natural gas (salt caverns, depleted hydrocarbon reservoirs, and deep aquifers) into underground dihydrogen (H2) storage reservoirs.

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