Chapter 9 Membrane lipids of archaea
TL;DR: The existence of such a large variety of unusual lipid structures in archaea raises questions concerning the biosynthetic pathways for these lipids and their function in archaeal membranes, and also concerning the evolutionary relationships within the archaea and among archaea, eubacteria and eukarya.

Taxonomic Significance of the Distribution of Component Parts of Polar Ether Lipids in Methanogens
TL;DR: In this article, a determinative key of methanogens, only based on lipid component analysis, is proposed, which can become a new chemotaxonomic marker, which utilises more lipid-structureoriented information than a thin-layer chromatographic pattern.

Structural and physicochemical properties of polar lipids from thermophilic archaea
TL;DR: This microreview focuses primarily on structural and physicochemical properties of polar lipids of (hyper)thermophilic archaea.

Membrane homeoviscous adaptation in the piezo-hyperthermophilic archaeon Thermococcus barophilus
TL;DR: The archaeon Thermococcus barophilus, one of the most extreme members of hyperthermophilic piezophiles known thus far, is able to grow at temperatures up to 103°C and pressures up to 80 MPa, and analyzed the membrane lipids by high performance liquid chromatography–mass spectrometry as a function of pressure and temperature.
Respiratory quinones in Archaea: phylogenetic distribution and application as biomarkers in the marine environment

TL;DR: Quinone distributions indicate that Thaumarchaeota dominate respiratory activity at a narrow interval in the chemocline, while they contribute only 9% to the microbial biomass at this depth, as determined by membrane lipid analysis.

Towards a natural system of organisms: proposal for the domains Archaea, Bacteria, and Eucarya.
TL;DR: It is proposed that a formal system of organisms be established in which above the level of kingdom there exists a new taxon called a "domain." Life on this planet would be seen as comprising three domains, the Bacteria, the Archaea, and the Eucarya, each containing two or more kingdoms.

Acidianus infernus gen. nov., sp. nov., and Acidianus brierleyi Comb. nov.: Facultatively Aerobic, Extremely Acidophilic Thermophilic Sulfur-Metabolizing Archaebacteria
TL;DR: A new genus, Acidianus, is characterized from studies of 26 isolates of thermoacidophilic archaebacteria from different solfatara fields and marine hydrothermal systems; these isolates grow as facultative aerobes by lithotrophic oxidation and reduction of SO, respectively, and are therefore different from the strictly aerobic Sulfolobus species.
