Purification of glycerol dialkyl nonitol tetraether from Sulfolobus acidocaldarius.
Journal of Lipid Research, 1989 A modified procedure for extraction and purification of hydrolyzed archaebacterial lipids is described. Lipids were extracted from Sulfolobus acidocaldarius using a Soxhlet extraction procedure followed by trichloroacetic acid solvent-extraction of the ...

OPTiMAL: a new machine learning approach for GDGT-based palaeothermometry [PDF]
Climate of the Past, 2020 In the modern oceans, the relative abundances of glycerol dialkyl glycerol tetraether (GDGT) compounds produced by marine archaeal communities show a significant dependence on the local sea surface temperature at the site of deposition. When preserved in

The effect of meter-scale lateral oxygen gradients at the sediment-water interface on selected organic matter based alteration, productivity and temperature proxies [PDF]
Biogeosciences, 2012 A valid assessment of selective aerobic degradation on organic matter (OM) and its impact on OM-based proxies is vital to produce accurate environmental reconstructions. However, most studies investigating these effects suffer from inherent environmental

Planktonic Euryarchaeota are a significant source of archaeal tetraether lipids in the ocean [PDF]
Proceedings of the National Academy of Sciences, 2014 Significance All three domains of life—Eukarya, Bacteria, and Archaea—are known to inhabit the marine water column from surface waters to great depth. Planktonic marine Archaea are comprised of two dominant groups—the Thaumarchaeaota and Euryarchaeota.

Identification and significance of unsaturated archaeal tetraether lipids in marine sediments [PDF]
Rapid Communications in Mass Spectrometry, 2014 RATIONALE Studies of archaeal glycerol dibiphytanyl glycerol tetraethers (GDGTs) in the environment and cultures have exclusively focused on compounds with fully saturated alkyl moieties. Here we report a number of novel unsaturated GDGTs (uns‐GDGTs) whose alkyl chains contain up to six double bonds and zero to ...
