Nature and Extent of the Deep Biosphere
Reviews in Mineralogy and Geochemistry, 2013In the last three decades we have learned a great deal about microbes in subsurface environments. Once, these habitats were rarely examined, perhaps because so much of the life that we are concerned with exists at the surface and seems to pace its metabolic and evolutionary rhythms with the overt planetary, solar, and lunar cycles that dictate our own ...

Radionuclide Geomicrobiology of the Deep Biosphere
Geomicrobiology Journal, 2011This review summarizes research into interactions between microorganisms and radionuclides under conditions typical of a repository for high-level radioactive waste in deep hard rock environments at a depth of approximately 500 m. The cell–radionuclide interactions of strains of two bacterial species (i.e., Shewanella putrefaciens and Desulfovibrio ...

The deep subterranean biosphere
Earth-Science Reviews, 1993Abstract The main purpose with this review is to summarise present research on the microbiology of deep subterranean environments, deeper than 50–100 m. Included are mainly studies where drilling, excavation, core sampling and ground water sampling have been made for research.

Deep Biosphere: Microbiome of the Deep Terrestrial Subsurface
2019Deep biosphere represents an unexplored realm of planetary life residing underneath the continental and oceanic crusts that constitutes majorly of prokaryotic life forms bacteria and archaea. Microbial communities which reside within various deep subsurface environments form a significant but largely unknown portion of the Earth’s biosphere.

The deep subsurface biosphere is alive and well
Trends in Microbiology, 2005For the first time, metabolically active bacterial cells have recently been quantified in deep marine sediments. In contrast to previous total cell counts that do not differentiate between active cells and inactive or dormant cells, these quantifications using oligonucleotide hybridization probes target active cells and their ribosomal (r)RNA.

Microbiology of the Deep Continental Biosphere
2016Subsurface microbial communities in sediment and fractured rock environments beneath continental surface environments and beneath the ocean floor comprise a significant but largely unexplored portion of the Earth’s biosphere. The continental subsurface is highly geologically varied, and so the abundance, diversity, and metabolic functions of its ...

Microbial Life of the Deep Biosphere
2014This book brings together a variety of topics, covering the broad range of issues that are associated with deep biosphere exploration. In order to explain our observations from deep subsurface ecosystems it is necessary to develop interdisciplinary approaches, ranging from microbiology and geochemistry to physics and modeling.
