Isolation and characterization of electrochemically active subsurface Delftia and Azonexus species

Frontiers in Microbiology, 2016
Continental subsurface environments can present significant energetic challenges to the resident microorganisms. While these environments are geologically diverse, potentially allowing energy harvesting by microorganisms that catalyze redox reactions ...

Microbial diversity gradients in the geothermal mud volcano underlying the hypersaline Urania Basin

Frontiers in Microbiology, 2022
Mud volcanoes transport deep fluidized sediment and their microbial communities and thus provide a window into the deep biosphere. However, mud volcanoes are commonly sampled at the surface and not probed at greater depths, with the consequence that ...

Microbiological influences on fracture surfaces of intact mudstone and the implications for geological disposal of radioactive waste [PDF]

, 2011
The significance of the potential impacts of microbial activity on the transport properties of host rocks for geological repositories is an area of active research. Most recent work has focused on granitic environments. This paper describes pilot studies

Experimental and simulation efforts in the astrobiological exploration of exooceans [PDF]

, 2020
The icy satellites of Jupiter and Saturn are perhaps the most promising places in the Solar System regarding habitability. However, the potential habitable environments are hidden underneath km-thick ice shells.

Succession Patterns and Physical Niche Partitioning in Microbial Communities from Subsurface Coal Seams

iScience, 2019
Summary: The subsurface represents a largely unexplored frontier in microbiology. Here, coal seams present something of an oasis for microbial life, providing moisture, warmth, and abundant fossilized organic material.

Deep Subsurface Microbiology

, 2015
Deep subsurface microbiology is a highly active and rapidly advancing research field at the interface of microbiology and the geosciences; it focuses on the detection, identification, quantification, cultivation and activity measurements of bacteria, archaea and eukaryotes that permeate the subsurface biosphere of deep marine sediments and the basaltic

The DynaDeep observatory – a unique approach to study high-energy subterranean estuaries

Frontiers in Marine Science, 2023
Subterranean estuaries are connective zones between inland aquifers and the open sea where terrestrial freshwater and circulating seawater mix and undergo major biogeochemical changes.

Microbiological Quality of Subsurface Drainage Water from Irrigated Agricultural Land [PDF]

Journal of Environmental Quality, 1972
AbstractIrrigation and subsurface drainage waters sampled from an 82,150‐hectare (203,000‐acre) irrigation district in southern Idaho were evaluated for bacteriological quality. The soils in the district are wind deposited over fractured basalt, calcareous, and have a pH near 7.8.

Microbiological Comparisons within and across Contiguous Lacustrine, Paleosol, and Fluvial Subsurface Sediments [PDF]

Applied and Environmental Microbiology, 1995
Twenty-six subsurface samples were collected from a borehole at depths of 173.3 to 196.8 m in the saturated zone at the Hanford Site in south-central Washington State. The sampling was performed throughout strata that included fine-grained lacustrine (lake) sediments, a paleosol (buried soil) sequence, and coarse-grained fluvial (river) sediments.
