Glycerol tetraethers with head-to-head isoprenoid 40-carbon chains that are typical of archaebacteria, in particular of methanogens, were identified in the polar lipids of sediments and petroleums. These structures are at least partially preserved in the subsurface beyond the stage of petroleum formation. Their identification provides further evidence that a significant part of geological organic matter derives from the lipids of membranes of microorganisms. 
Ether lipids of planktonic archaea in the marine water column
Compound-specific isotope analyses of the carbon skeletons suggest that planktonic archaea utilize an isotopically heavy carbon source such as algal carbohydrates and proteins or dissolved bicarbonate. Expand
Petroleum isoprenoid hydrocarbons derived from catagenetic degradation of archaebacterial lipids
Abstract The three GC coeluting C 40 bis-phytanes with head-to-tail, tail-to-tail and head-to-head linkages considered to be archaebacterial markers, have been recognized in petroleum by enhancedExpand
Acyclic archaebacterial ether lipids in swamp sediments
Abstract Acyclic phytanyl diether glycerol and biphytanyl ether lipids have been quantified in two modern swamp sediment cores in concentrations ranging up to 360 μg/ml porewater. MethanogenicExpand
Archaebacterial ether lipids: Natural tracers of biogeochemical processes
Abstract Methanogen ether lipids have been quantified in sediments from a Florida swamp and the Atlantic ocean. Swamp cores containing acyclic and monocyclic isopranyl ethers are clearlyExpand

ABSTRACT The kingdom Crenarchaeota is now known to include archaea which inhabit a wide variety of low-temperature environments. We report here lipid analyses of nonthermophilic crenarchaeotes, whichExpand
High proportions of tetraether phospholipids in Methanobacterium thermoautotrophicum strain Hveragerdi measured by high performance liquid chromatography
The diether and tetraether lipids were isolated from the phospholipids of Methanobacterium thermoautotrophicum strain Hveragerdi and the ratio of diether to tetra Ether lipids was 1:14 on a weight basis and represents the highest proportion of tetra ether yet reported in a methanogenic bacterium.

Archaea in Black Sea water column particulate matter and sediments—evidence from ether lipid derivatives
Abstract Phytane and long-chain, C40, head-to-head acyclic (C40:0cy) and cyclic isoprenoids with 1–3 cyclopentyl rings (C40:1cy, C40:2cy, and C40:3cy) derived from archaeal core lipids are present inExpand
Bacteriohopanetetrol from chemical degradation of an oil shale kerogen
Microbial lipids play an important role in the formation of geologically derived organic matter1. Among these lipids the hopanoids have a key function as they show an almost ubiquitous occurrence inExpand
Production of pristane and phytane in the marine environment: role of prokaryotes.
Prokaryotes appear to play a key role in formation of these isoprenoid alkanes in the marine environment. Expand
Anaerobic bacterial degradation of pristenes and phytenes in marine sediments does not lead to pristane and phytane during early diagenesis
Abstract Anaerobic degradation of mixtures of isomeric pristenes and phytenes by sedimentary bacterial communities was investigated. These isoprenoid alkenes were quickly metabolized withoutExpand


Novel complex polar lipids from the methanogenic archaebacterium Methanospirillum hungatei.
The methanogenic archaebacterium Methanospirillum hungatei contains two unusual phosphoglycolipids that account for 64 percent of the total cellular lipids and may function as covalently bonded lipid bilayers to impart stability and rigidity to methanogen membranes. Expand

Characterization of these lipids resulted in their identification as dialkyl glyceryl ether and diglycerol tetraethers, and the ether-linked alkyl chains were identified as the 20- and 40-carbon branched chains for the diether and tetra ether, respectively. Expand
Chemical structure of the ether lipids of thermophilic acidophilic bacteria of the Caldariella group
Abstract The lipids of the Caldariella group of extremely thermophilic acidophilic bacteria are based on a 72-membered macrocyclic tetraether made up from two C40 diol units and either two glycerolExpand
Diphytanyl and dibiphytanyl glycerol ether lipids of methanogenic archaebacteria.
The occurrence of both types of isopranyl glycerol ethers in methanogenic bacteria supports the proposal that they have a close genealogical relationship to the extremely halophilic and thermoacidophilic bacteria. Expand
The Hopanoids: palaeochemistry and biochemistry of a group of natural products
More than 100 individual derivatives of hopane have been isolated from sedimentary organic matter of most varied origin. They are ubiquitous molecular fossils derived from cellular constituents ofExpand
Specific acyclic isoprenoids as biological markers of methanogenic bacteria in marine sediments
The first recognition of 2,6,10,15,19,19-pentamethyleicosane (II), a known component of methanogens5, 6, in marine sediments of Recent to Cretaceous age is reported and it is suggested that it and certain other acyclic isoprenoids may be used as biological markers for meethanogens. Expand
Structure of calditol, a new branched-chain nonitol, and of the derived tetraether lipids in thermoacidophile archaebacteria of the Caldariella group
A second category of membrane lipids in extreme thermoacidophile archaebacteria of the Caldariella group is based on the same type of macrocyclic tetraether, incorporating two 16,16′-biphytanyl chains, but only one of the hydrophobic components is glycerol; the second hydrophilic component is calditol, a unique branched-chain nonitol.
