Geological processes mediate a microbial dispersal loop in the deep biosphere. [PDF]
Sci Adv, 2022 The deep biosphere is the largest microbial habitat on Earth and features abundant bacterial endospores. Whereas dormancy and survival at theoretical energy minima are hallmarks of microbial physiology in the subsurface, ecological processes such as ...

Thermochronologic perspectives on the deep-time evolution of the deep biosphere. [PDF]
Proc Natl Acad Sci U S A, 2021 Significance The Earth’s deep biosphere is one of the least explored and understood environments. It hosts microbial lineages that are of interest for understanding the origin and evolution of life on our planet.

Lipid analysis of CO2-rich subsurface aquifers suggests an autotrophy-based deep biosphere with lysolipids enriched in CPR bacteria. [PDF]
ISME J, 2020 Sediment-hosted CO2-rich aquifers deep below the Colorado Plateau (USA) contain a remarkable diversity of uncultivated microorganisms, including Candidate Phyla Radiation (CPR) bacteria that are putative symbionts unable to synthesize membrane lipids ...

Cold seep formation from salt diapir-controlled deep biosphere oases. [PDF]
Proc Natl Acad Sci U S ASignificance We provide compelling evidence that highly biologically diverse deep marine cold seeps can arise, and be further maintained, by methane supplied from methanogenic archaeal deep biosphere oases.

Rock-crushing derived hydrogen directly supports a methanogenic community: significance for the deep biosphere. [PDF]
Environ Microbiol Rep, 2019 Summary Microbial populations exist to great depths on Earth, but with apparently insufficient energy supply. Earthquake rock fracturing produces H2 from mechanochemical water splitting, however, microbial utilization of this widespread potential energy ...

Statistical Analysis of Community RNA Transcripts between Organic Carbon and Geogas-Fed Continental Deep Biosphere Groundwaters. [PDF]
mBio, 2019 Despite being separated from the photosynthesis-driven surface by both distance and time, the deep biosphere is an important driver for the earth’s carbon and energy cycles.

A new macrofaunal limit in the deep biosphere revealed by extreme burrow depths in ancient sediments. [PDF]
Sci Rep, 2018 Macrofauna is known to inhabit the top few 10s cm of marine sediments, with rare burrows up to two metres below the seabed. Here, we provide evidence from deep-water Permian strata for a previously unrecognised habitat up to at least 8 metres below the ...
