The cytoplasmic membrane of bacteria and archaea determine to a large extent the
composition of the cytoplasm. Since the ion and in particular the proton and/or the sodium …

In extreme environments, mainly Archaea are encountered. The archaeal cytoplasmic
membrane contains unique ether lipids that cannot easily be degraded, are temperature …

An isolate of an acidophilic archaeon, strain YT, was obtained from a bioleaching pilot plant.
The organism oxidizes ferrous iron as the sole energy source and fixes inorganic carbon as …

We investigated the distributions and δ13C values of biomarkers for Archaea associated
with anaerobic methane oxidation in disparate settings throughout two Eastern …

Recent work has highlighted the ubiquity of bacteria and archaea and continues to affirm
their significance in diverse biogeochemical processes. The δ13C values and distributions …

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

Microbes often face contrasted and fluctuating environmental conditions, to which they need
to adapt or die. Because membranes play a central role in regulating fluxes inward and …

Halophilic Archaea of the order Halobacteriales are found in hypersaline environments in
which salt concentrations exceed 150–200 g/liter. They inhabit salt lakes such as the Great …

In this review, the history of the classification of the family Halobacteriaceae, the extremely
halophilic aerobic Archaea, is reviewed with some emphasis on the recently described new …

The 16S rRNA genes of three species of the genus Natronobacterium (Natronobacterium
gregoryi, Natronobacterium pharaonis, and Natronobacterium vacuolatum) were sequenced …
