  • 1 March 2007
SUMMARY This review deals with the in vitro biosynthesis of the characteristics of polar lipids in archaea along with preceding in vivo studies. Isoprenoid chains are synthesized through theExpand
Aeropyrum pernix gen. nov., sp. nov., a Novel Aerobic Hyperthermophilic Archaeon Growing at Temperatures up to 100°C
A novel aerobic hyperthermophilic archaeon was isolated from a coastal solfataric vent at Kodakara-Jima Island, Japan. The new isolate, strain K1, is the first strictly aerobic organism growing atExpand

  • 1 January 2005
A great number of novel and unique chemical structures of archaeal polar lipids have been reported. Since 1993, when those lipids were reviewed in several review articles, a variety of core lipidsExpand
A novel ether core lipid with H-shaped C80-isoprenoid hydrocarbon chain from the hyperthermophilic methanogen Methanothermus fervidus.
A new ether lipid core (designated as FU) was found in Methanothermus fervidus total lipid. Comparison with caldarchaeol showed lower mobility of FU on TLC and smaller molecular weight (m/z 1298) byExpand

  • 15 August 2012
The physiological characteristics that distinguish archaeal and bacterial lipids, as well as those that define thermophilic lipids, are discussed from three points of view that (1) the role of theExpand
Correlation of Polar Lipid Composition with 16S rRNA Phylogeny in Methanogens. Further Analysis of Lipid Component Parts.
Qualitative analyses of lipid component parts (core lipids, phospholipid-polar head groups, and glycolipid-sugar moieties) without separation of individual lipids were done for further 14 strains ofExpand
Ether polar lipids of methanogenic bacteria: structures, comparative aspects, and biosyntheses.
Complete structures of nearly 40 ether polar lipids from seven species of methanogens have been elucidated during the past 10 years. Three kinds of variations of core lipids, macrocyclic archaeol andExpand
Did Archaeal and Bacterial Cells Arise Independently from Noncellular Precursors? A Hypothesis Stating That the Advent of Membrane Phospholipid with Enantiomeric Glycerophosphate Backbones Caused the
One of the most remarkable biochemical differences between the members of two domains Archaea and Bacteria is the stereochemistry of the glycerophosphate backbone of phospholipids, which areExpand
Extraction and composition of polar lipids from the archaebacterium, Methanobacterium thermoautotrophicum: effective extraction of tetraether lipids by an acidified solvent.
The usual Bligh and Dyer method could extract only a small part of the lipids of Methanobacterium thermoautotrophicum. When the water in the solvent was replaced by 5% trichloroacetic acid, the lipidExpand
Aeropyrum pernix gen. nov., sp. nov., a novel aerobic hyperthermophilic archaeon growing at temperatures up to 100 degrees C.
A novel aerobic hyperthermophilic archaeon was isolated from a coastal solfataric vent at Kodakara-Jima Island, Japan. The new isolate, strain K1, is the first strictly aerobic organism growing atExpand
