The past decade has revealed the diversity and ubiquity of archaea in nature, with a growing
number of studies highlighting their importance in ecology, biotechnology and even human …

Why do bacteria have shape? Is morphology valuable or just a trivial secondary
characteristic? Why should bacteria have one shape instead of another? Three broad …

A range of bacteria and archaea produce intracellular gas-filled proteinaceous structures
that function as flotation devices in order to maintain a suitable depth in the aqueous …

Le domaine des archéens représente une troisième lignée de descendance dans
l'évolution, distincte des bactéries et des eucaryotes. Les premières études ont semblé …

Background The square halophilic archaeon Haloquadratum walsbyi dominates NaCl-
saturated and MgCl 2 enriched aquatic ecosystems, which imposes a serious desiccation …

Archaea play indispensable roles in global biogeochemical cycles, yet many crucial cellular
processes, including cell-shape determination, are poorly understood. Haloferax volcanii, a …

Thomas D. Brock defined extreme environments, considering that there are environments
with high species diversity and others with low species diversity. Those environments with …

Hypersaline environments are dominated by archaea and bacteria and are almost entirely
devoid of eukaryotic organisms. In addition, hypersaline environments contain considerable …

(Cas) system provides adaptive and heritable immunity against foreign genetic elements in …

As a group, the halophilic archaea (class Halobacteria) are the most salt-requiring and salt-
resistant microorganisms within the domain Archaea. Halophilic archaea flourish in …
