Microbial activities in deep subsurface environments [PDF]
Geomicrobiology Journal, 1989 Abstract Activities of microorganisms residing in terrestrial deep subsurface sediments were examined in 46 sediment samples from three boreholes. Radiolabeled time course experiments assessing in situ microbial activities were initiated within 30 min of core recovery.

Soil and water pollution in a banana production region in tropical Mexico [PDF]
, 2010 The effects of abundant Mancozeb (Mn, Zn— bisdithiocarbamate) applications (2.5 kg ha-1week-1 for 10 years) on soil and surface-, subsurface- and groundwater pollution were monitored in a banana production region of tropical Mexico.

Active anaerobic methane oxidation and sulfur disproportionation in the deep terrestrial subsurface
The ISME Journal, 2021 Microbial life is widespread in the terrestrial subsurface and present down to several kilometers depth, but the energy sources that fuel metabolism in deep oligotrophic and anoxic environments remain unclear.

Deep carbon storage potential of buried floodplain soils. [PDF]
, 2017 Soils account for the largest terrestrial pool of carbon and have the potential for even greater quantities of carbon sequestration. Typical soil carbon (C) stocks used in global carbon models only account for the upper 1 meter of soil.

The deep continental subsurface: the dark biosphere [PDF]
International Microbiology, 2018 Although information from devoted geomicrobiological drilling studies is limited, it is clear that the results obtained so far call for a systematic exploration of the deep continental subsurface, similar to what has been accomplished in recent years by the Ocean Drilling Initiatives.

Deep-branching acetogens in serpentinized subsurface fluids of Oman
Proceedings of the National Academy of Sciences of the United States of America, 2022 Significance Acetate-producing microorganisms (acetogens) have long been hypothesized as among the earliest evolving organisms. Concomitantly, serpentinite formations have been widely considered the most likely habitat to have supported early life.

Dark Fermentation in the Dark Biosphere: The Case of Citrobacter sp. T1.2D-12
Fermentation, 2023 Microbial diversity that thrives in the deep subsurface remains largely unknown. In this work, we present the characterization of Citrobacter sp. T1.2D-1, isolated from a 63.6 m-deep core sample extracted from the deep subsurface of the Iberian Pyrite ...

Lord Coke, the Restatement, and Modern Subsurface Trespass Law [PDF]
, 2011 The First Restatement of Property provides that “‘property’ . . . denote[s] legal relations between persons with respect to a thing.” The “thing” considered in this article is the subsurface of real property, and the legal relationship involved in the ...

Hypotheses for near-surface exchange of methane on Mars [PDF]
, 2016 The Curiosity rover recently detected a background of 0.7 ppb and spikes of 7 ppb of methane on Mars. This in situ measurement reorients our understanding of the Martian environment and its potential for life, as the current theories do not entail any ...
