Archaebacterial lipids in hot-spring microbial mats
TL;DR: This work reports the first direct comparison between isopranyl ether-linked lipids in hot-spring microbial mats and the observed populations of archaebacteria, and finds that the phytanyl and biphytanyl ethers reflect the measured distribution of methanogenic archaEBacteria.

Petroporphyrins as indicators of geothermal maturation
TL;DR: Simulated geothermal maturation in the laboratory demonstrates that DPEP–etio conversion occurs proportionally to the severity of the treatment, and an analysis of petroporphyrins from a suite of genetically related petroleums and their source rocks reveal that the DPEP:etio ratio is inversely proportional to the presumed severity ofThe geothermal history of the sample.

TL;DR: In this article, the results show that lipids of differing origin are concentrated in different size particles of Severn Estuary mud and that the PAH mainly derived from combustion of fossil fuels are present in greatest proportion in the ‘sand’ fraction.

The lipid chemistry of an interfacial sediment from the Peru Continental Shelf: Fatty acids, alcohols, aliphatic ketones and hydrocarbons
TL;DR: A sample of sediment-water column interface which lies on the continental shelf under the Peru upwelling regime, has been examined for fatty acids, fatty alcohols, ketones and hydrocarbons as discussed by the authors.

The use of hydroxyacids as geochemical indicators
J. N. Cardoso,Geoffrey Eglinton +1 more
TL;DR: The distributions of hydroxyacids in a variety of recent and ancient sediments have been determined by gas chromatography-mass spectrometry as discussed by the authors, consistent with their presumed microbial origin, whereas di- and trihydroxyacids were present in the sediments with a significant higher plant input (Black Sea and Rostherne Mere).
