A wide array of microorganisms, including many novel, phylogenetically deeply rooted taxa,
survive and thrive in extreme environments. These unique and reduced-complexity …

▪ Abstract The recent recognition of a potentially vast, unexplored hot microbial biosphere
associated with active volcanism along the global mid-ocean ridge network has …

The search for extraterrestrial life may be facilitated if ecosystems can be found on Earth that
exist under conditions analogous to those present on other planets or moons. It has been …

Microbial communities from a subseafloor sediment core from the southwestern Sea of
Okhotsk were evaluated by performing both cultivation-dependent and cultivation …

Microbes in marine sediments represent a large portion of the biosphere, and resolving their
ecology is crucial for understanding global ocean processes. Single-gene diversity surveys …

The eocyte hypothesis, in which Eukarya emerged from within Archaea, has been boosted
by the description of a new candidate archaeal phylum,“Lokiarchaeota”, from metagenomic …

Subsurface microbial communities supported by geologically and abiologically derived
hydrogen and carbon dioxide from the Earth's interior are of great interest, not only with …

Thermophilic microbial inhabitants of active seafloor and continental hot springs populate
the deepest branches of the universal phylogenetic tree, making hydrothermal ecosystems …

In contrast to the high accumulation in sequence data for hyperthermophilic archaea,
methodology for genetically manipulating these strains is still at an early stage. This study …

Prokaryotes inhabiting in the deep sea vent ecosystem will thus experience harsh conditions
of temperature, pH, salinity or high hydrostatic pressure (HHP) stress. Among the fifty-two …
