Planktonic Euryarchaeota are a significant source of archaeal tetraether lipids in the ocean [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 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.

Application of microbial membrane tetraether lipids in speleothems
Frontiers in Ecology and Evolution, 2023 Glycerol dialkyl glycerol tetraethers (GDGTs), which are derived from microbial membranes, occur widely in soils, peats, lake sediments, marine sediments, hot springs, and other environments.

The Role of Tetraether Lipid Composition in the Adaptation of Thermophilic Archaea to Acidity [PDF]
Frontiers in Microbiology, 2013 Diether and tetraether lipids are fundamental components of the archaeal cell membrane. Archaea adjust the degree of tetraether lipid cyclization in order to maintain functional membranes and cellular homeostasis when confronted with pH and/or thermal ...

Lipid hydrogen isotope compositions primarily reflect growth water in the model archaeon Sulfolobus acidocaldarius [PDF]
Applied and Environmental MicrobiologyThe stable hydrogen isotope composition (δ2H) of lipid biomarkers can track environmental processes and remain stable over geologically relevant time scales, enabling studies of past climate, hydrology, and ecology.

Production of branched tetraether lipids in the lower Pearl River and estuary: effects of extraction methods and impact on bGDGT proxies [PDF]
Frontiers in Microbiology, 2012 Branched glycerol dibiphytanyl glycerol tetraethers (bGDGTs) are known as bacterial lipids that occur widely in terrestrial environments, particularly in anaerobic peat bogs and soil.

Environmental Controls on Crenarchaeol Distributions in Hydrothermal Springs [PDF]
Environ MicrobiolThe optimal pH and temperature for crenarchaeol (a unique archaeal lipid) production in hydrothermal springs are 7.4°C and 46°C, respectively, which has important implications for archaeal evolution. Our study also indicates that pH is the most important environmental variable for archaeal lipid membrane compositions.

Structure-function relationships in pure archaeal bipolar tetraether lipids. [PDF]
Chem Sci, 2023 A series of archaeal bipolar glycerol dialkyl glycerol tetraether (GDGT) lipids were synthesized. Structural properties of self-assembled structures of GDGTs were studied and related to functional behavior such as membrane fusion.

Planktonic Archaeal Ether Lipid Origins in Surface Waters of the North Pacific Subtropical Gyre
Frontiers in Microbiology, 2021 Thaumarchaeota and Thermoplasmatota are the most abundant planktonic archaea in the sea. Thaumarchaeota contain tetraether lipids as their major membrane lipids, but the lipid composition of uncultured planktonic Thermoplasmatota representatives remains ...
