The deep terrestrial biosphere encompasses the life below the photosynthesis-fueled
surface that perseveres in typically nutrient and energy depleted anoxic groundwaters. The …

Earth's deep continental subsurface is a prime setting to study the limits of life's relationship
with environmental conditions and habitability. In Precambrian crystalline rocks worldwide …

The continental bedrock contains groundwater-bearing fractures that are home to microbial
populations that are vital in mediating the Earth's biogeochemical cycles. However, their …

The microbiome of deep continental aquifers is considered the most slowly evolving part of
the biosphere. The Yessentukskoye Mineral Water Basin (YMWB), located in the pre …

The class Limnochordia harbors a single cultivated member, the mesophilic Limnochorda
pilosa, which was isolated from a meromictic lake. Despite numerous molecular signatures …

Dissolved inorganic carbon has been hypothesized to stimulate microbial chemoautotrophic
activity as a biological sink in the carbon cycle of deep subsurface environments. Here, we …

Coastal waters such as those found in the Baltic Sea already suffer from anthropogenic
related problems including increased algal blooming and hypoxia while ongoing and future …

Deep fracture‐hosted fluids of Precambrian bedrock cratons are relatively stagnant over
long time spans compared to near‐surface systems. However, episodic events, such as …

The continental deep biosphere contains a vast reservoir of microorganisms, although a
large proportion of its diversity remains both uncultured and undescribed. In this study, the …

The deep biosphere refers to the vast ecosystem of life beneath the Earth's surface, residing
in the fractured bedrock and pores of rocks, largely isolated from solar energy. These …
