Microorganisms that adapt to moderate and high salt environments use a variety of solutes,
organic and inorganic, to counter external osmotic pressure. The organic solutes can be …

No organism can survive across the entire temperature range found in the biosphere, and a
given species can rarely support active metabolism across more than a few tens of° C …

Extremophilic microorganisms have adopted a variety of ingenious strategies for survival
under high or low temperature, extreme pressure, and drastic salt concentrations. A novel …

The availability of water is the most important prerequisite for life of any living cell, and
exposure of cells to hypersaline conditions always threatens the cells with a drastic loss of …

Microorganisms respond to osmotic stress mostly by accumulating compatible solutes, either
by uptake from the medium or by de novo synthesis. These osmotically active molecules …

The accumulation of organic solutes is a prerequisite for osmotic adjustment of all
microorganisms. Thermophilic and hyperthermophilic organisms generally accumulate very …

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

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 …

Covering: up to early 2008 In order to survive extremes of pH, temperature, salinity and
pressure, organisms have been found to develop unique defences against their …

The ability to adapt to ffuctuations in external osmotic pressure (osmoadaptation) and the
development of specific mechanisms to achieve this (osmoregulation) are fundamental to …
