Ribosomal DNA (rDNA) sequences have been aligned and compared in a number of living
organisms, and this approach has provided a wealth of information about phylogenetic …

Many archaea are extremophiles. They thrive at high temperatures, at high pressure and in
concentrated acidic environments. Nevertheless, the largest proportion and greatest …

The recently described aerobic, extremely halophilic archaeobaterium, Halobacterium
lacusprofundi was subjected to lipid analysis so that comparisons could be made between …

Abstract The Second Edition of Bergey's Manual of Systematic Bacteriology represents a
major departure from the First Edition, as well as from the Eighth and Ninth Editions of the …

For practical purposes, the growth medium should be defined as “rich”, or more accurately,
the medium that supports the most rapid growth under optimal salt concentrations. To return …

In hypersaline environments, Nanohaloarchaeota (Diapherotrites, Parvarchaeota,
Aenigmarchaeota, Nanoarchaeota, Nanohaloarchaeota [DPANN] superphylum) are thought …

Archaebacterial halophiles (Haloarchaea) are oxygen-respiring heterotrophs that derive
from methanogens—strictly anaerobic, hydrogen-dependent autotrophs. Haloarchaeal …

Increased membrane fluidity, which causes cofactor leakage and loss of membrane
potential, has long been documented as a cause for decreased cell growth during exposure …

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

The Archaea evolved as one of the three primary lineages several billion years ago, but the
first archaea to be discovered were described in the scientific literature about 130 years ago …
