Subsurface Microbial Habitats in an Extreme Desert Mars-Analog Environment

Frontiers in Microbiology, 2019
Sediments in the hyper-arid core of the Atacama Desert are a terrestrial analog to Mars regolith. Understanding the distribution and drivers of microbial life in the sediment may give critical clues on how to search for biosignatures on Mars.

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 ...

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.

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.

An Ionic Limit to Life in the Deep Subsurface

Frontiers in Microbiology, 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.

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

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.

Bacterial community dissimilarity between the surface and subsurface soils equals horizontal differences over several kilometers in the western Tibetan Plateau.

Environmental Microbiology, 2016
Many studies have investigated patterns in the near-surface soil microbial community over large spatial scales. However, less is known about variation in subsurface (15-30 cm of depth) microbial communities.
