Subsurface microbial habitats on Mars [PDF]
We developed scenarios for shallow and deep subsurface cryptic niches for microbial life on Mars. Such habitats could have considerably prolonged the persistence of life on Mars as surface conditions became increasingly inhospitable.

Ecological and Genomic Attributes of Novel Bacterial Taxa That Thrive in Subsurface Soil Horizons. [PDF]
, 2019 While most bacterial and archaeal taxa living in surface soils remain undescribed, this problem is exacerbated in deeper soils, owing to the unique oligotrophic conditions found in the subsurface.

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract Xenon (Xe) is a heavy noble gas with intriguing chemical properties, such as having several stable isotopes and the ability to form compounds under extreme conditions. Despite the predictions based on cosmochemical models that suggest xenon should be relatively abundant in planetary reservoirs, empirical data indicate a significant depletion ...

Consumption of Methane and CO_2 by Methanotrophic Microbial Mats from Gas Seeps of the Anoxic Black Sea [PDF]
, 2007 The deep anoxic shelf of the northwestern Black Sea has numerous gas seeps, which are populated by methanotrophic microbial mats in and above the seafloor.

Water Resources Research, Volume 62, Issue 4, April 2026.Abstract In situ remediation of contaminated soil and groundwater demands real‐time monitoring to capture complex subsurface dynamics. Geophysical methods, particularly electrical resistivity tomography (ERT) and induced polarization (IP), offer non‐ or minimally invasive, high‐resolution imaging of subsurface changes during remediation.

Recovery and Origin of Subsurface Microbiological Contamination from an Acrylic Latex Coating
Journal of Applied Poultry Research, 1995 Abstract This study investigated the potential subsurface retention of microbes including foodborne pathogens by coatings applied to poultry processing plant walls and ceilings. Recovery and origin of subsurface microbial contamination of an acrylic latex coating in a simulated poultry processing plant environment with or without sanitation were ...

Environmental Microbiology, Volume 28, Issue 4, April 2026.In this cultivation‐based study, two novel moderately thermophilic Nitrospira enrichments were obtained from the geothermal field Las Máquinas in the Neuquén Province, Argentina. Both nitrite oxidizers, belonging to lineage V or the novel taxonomic lineage VIII, contain quorum‐sensing genes and a high genome GC content of 60.6% and 69.4%.

Microbiological Comparison of Surface Soil and Unsaturated Subsurface Soil from a Semiarid High Desert [PDF]
Applied and Environmental Microbiology, 1989 Thirty-two chemoheterotrophic bacteria were isolated from unsaturated subsurface soil samples obtained from ca. 70 m below land surface in a high desert in southeastern Idaho. Most isolates were gram positive (84%) and strict aerobes (79%). Acridine orange direct counts of microbes in one subsurface sample showed lower numbers than similar
