Microbial activity in the marine deep biosphere: Progress and prospects

open access: yesFrontiers in Microbiology, 2013
The vast marine deep biosphere consists of microbial habitats within sediment, pore waters, upper basaltic crust and the fluids that circulate throughout it.

Prokaryotic communities from a lava tube cave in La Palma Island (Spain) are involved in the biogeochemical cycle of major elements [PDF]

open access: yesPeerJ, 2021
Lava caves differ from karstic caves in their genesis and mineral composition. Subsurface microbiology of lava tube caves in Canary Islands, a volcanic archipelago in the Atlantic Ocean, is largely unknown.

From Surface to Subsurface: Diversity, Composition, and Abundance of Sessile and Endolithic Bacterial, Archaeal, and Eukaryotic Communities in Sand, Clay and Rock Substrates in the Laurentians (Quebec, Canada)

open access: yesMicroorganisms, 2022
Microbial communities play an important role in shallow terrestrial subsurface ecosystems. Most studies of this habitat have focused on planktonic communities that are found in the groundwater of aquifer systems and only target specific microbial groups.

Shifts in the bacterial community composition along deep soil profiles in monospecific and mixed stands of Eucalyptus grandis and Acacia mangium [PDF]

open access: yes, 2017
Our knowledge of the rhizosphere bacterial communities in deep soils and the role of Eucalyptus and Acacia on the structure of these communities remains very limited.

Geological and Geochemical Controls on Subsurface Microbial Life in the Samail Ophiolite, Oman

open access: yesFrontiers in Microbiology, 2017
Microbial abundance and diversity in deep subsurface environments is dependent upon the availability of energy and carbon. However, supplies of oxidants and reductants capable of sustaining life within mafic and ultramafic continental aquifers undergoing

There's Plenty of Room at the Bottom: Low Radiation as a Biological Extreme

open access: yesFrontiers in Astronomy and Space Sciences, 2020
The effects of high radiation as a biological extreme have historically been, and continue to be, extensively researched in the fields of radiation biology and astrobiology.

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

open access: yesFrontiers 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 ...
