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

Rock Surface Fungi in Deep Continental Biosphere—Exploration of Microbial Community Formation with Subsurface In Situ Biofilm Trap [PDF]
Microorganisms, 2020 Fungi have an important role in nutrient cycling in most ecosystems on Earth, yet their ecology and functionality in deep continental subsurface remain unknown.

Active microbial biofilms in deep poor porous continental subsurface rocks [PDF]
Scientific Reports, 2018 Deep continental subsurface is defined as oligotrophic environments where microorganisms present a very low metabolic rate. To date, due to the energetic cost of production and maintenance of biofilms, their existence has not been considered in poor ...

Subduction hides high-pressure sources of energy that may feed the deep subsurface biosphere. [PDF]
Nat Commun, 2020 Geological sources of H2 and abiotic CH4 have had a critical role in the evolution of life and sustainability of the deep subsurface biosphere, yet the origins of these sources remain largely unconstrained.

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.

Dark Fermentation in the Dark Biosphere: The Case of Citrobacter sp. T1.2D-12
Fermentation, 2023 Microbial diversity that thrives in the deep subsurface remains largely unknown. In this work, we present the characterization of Citrobacter sp. T1.2D-1, isolated from a 63.6 m-deep core sample extracted from the deep subsurface of the Iberian Pyrite ...

Horizontal Stratification during Deep Convection in the Labrador Sea [PDF]
, 2014 Deep convection—the process by which surface waters are mixed down to 1000 m or deeper—forms the primary downwelling of the meridional overturning circulation in the Northern Hemisphere.
