Tracking microbial habitats in subseafloor sediments [PDF]
Proceedings of the National Academy of Sciences, 2012 Throughout the world’s oceans, the sediments that cover the seafloor, and the cracks and fissures of the basaltic ocean crust, are permeated by microbial life (1, 2). As these bacteria and archaea are mostly not available in laboratory culture and thus elude direct physiological characterization, Jorgensen et al.

Tracking Microbial Evolution in the Subseafloor Biosphere
mSystems, 2021 The deep marine subsurface constitutes a massive biosphere that hosts a multitude of archaea, bacteria, and viruses across a diversity of habitats. These microbes play key roles in mediating global biogeochemical cycles, and the marine subsurface is thought to have been among the earliest habitats for life on Earth.

Frontiers in Microbiology, 2013 Microbial processes within the subseafloor can be examined during the ephemeral and uncommonly observed phenomena known as snowblower venting. Snowblowers are characterized by the large quantity of white floc that is expelled from the seafloor following ...

Preparing for the new age of the Nagoya Protocol in scientific ocean drilling [PDF]
Scientific Drilling, 2018 Deep biosphere research has become one of the major scientific focuses in ocean drilling science. Increased scientific attention to microbiological research of the subseafloor environment raises the complications and concerns related to adherence to ...

Progress in Earth and Planetary Science, 2023 Microbes in marine sediments detected and counted by direct observation of membrane-filtered sediment samples stained with acridine orange. This technique can still be applied to high-biomass (> 105 cells/cm3) sedimentary habitats, such as organic-rich ...

Metagenomic Insights Into the Microbial Iron Cycle of Subseafloor Habitats
Frontiers in Microbiology, 2021 Microbial iron cycling influences the flux of major nutrients in the environment (e.g., through the adsorptive capacity of iron oxides) and includes biotically induced iron oxidation and reduction processes.

Physiological limits to life in anoxic subseafloor sediment [PDF]
FEMS Microbiology Reviews, 2020 ABSTRACTIn subseafloor sediment, microbial cell densities exponentially decrease with depth into the fermentation zone. Here, we address the classical question of 'why are cells dying faster than they are growing?’ from the standpoint of physiology. The stoichiometries of fermentative ATP production and consumption in the fermentation zone place bounds
