The increasing emergence of new forms of multidrug resistance among human pathogenic
bacteria, coupled with the consequent increase of infectious diseases, urgently requires the …

Members of the Roseobacter clade are equipped with a tremendous diversity of metabolic
capabilities, which in part explains their success in so many different marine habitats. Ideas …

The oceanic waters below a depth of 200 m represent, in terms of volume, the largest habitat
of the biosphere, harboring approximately 70% of the prokaryotic biomass in the oceanic …

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 …

By the end of the 19th century British and French oceanographic expeditions had shown that
life exists in the deepest ocean trenches. Since then, microorganisms have been found to …

Psychrophilic (cold-adapted) microorganisms make a major contribution to Earth's biomass
and perform critical roles in global biogeochemical cycles. The vast extent and …

Traditional culture techniques usually retrieve a small fraction of the marine microbial
diversity, which mainly belong to the so-called rare biosphere. However, this paradigm has …

Hadal trenches, oceanic locations deeper than 6,000 m, are thought to have distinct
microbial communities compared to those at shallower depths due to high hydrostatic …

Microbial life has been prevailing in the biosphere for the last 3.8 Ga at least. Throughout
most of the Earth's history it has experienced a range of pressures; both dynamic pressure …

The hadal zone is the deep ocean with depths exceeding 6000 m. With an area
approximately equal to the size of Australia, but constituting the deepest 45% of the vertical …
