Nonmarine crenarchaeol in Nevada hot springs
Article Abstract:
The lipid extracts of the samples of microbial community biomass obtained from several alkaline neutral-pH hot springs in Nevada, United States are analyzed by high-performance liquid chromatography-mass spectrometry. The occurrence of crenarchaeol in environments counting sequences affiliated with thermophilic crenarchaeota suggests a wide phenotypic distribution of this compound.

Thermophilic temperature optimum for crenarchaeol synthesis and its implication for archaeal evolution
Article Abstract:
The isoprenoid lipid crenarchaeol is widespread in hotsprings of California and Nevada and terrestrial and marine data together suggest a maximum relative abundance of crenarchaeol at -40 degrees Celsius. This warm temperature optimum may have facilitated colonization of the ocean by (hyper) thermophilic Archaea and the major marine radiation of Crenarchaeota.

Isolation, characterization, and ecology of sulfur-respiring Crenarchaea inhabiting acid-sulfate-chloride-containing geothermal springs in Yellowstone National Park
Article Abstract:
The isolation, characterization, and ecology of two novel, [S.sup.0]-reducing Crenarchaea from an acid geothermal spring are reported. Both isolates are capable of cycling sulphur in acid geothermal springs throughout the Yellowstone National Park geothermal complex.
