Gene Deletions Leading to a Reduction in the Number of Cyclopentane Rings in Sulfolobus acidocaldarius Tetraether Lipids. [PDF]

open access: yesFEMS Microbiology Letters, 2018
The cell membrane of (hyper)thermophilic archaea, including the thermoacidophile Sulfolobus acidocaldarius, incorporates dibiphytanylglycerol tetraether lipids.

Planktonic Euryarchaeota Are a Significant Source of Archaeal Tetraether Lipids in the Ocean [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2014
Archaea are ubiquitous in marine plankton, and fossil forms of archaeal tetraether membrane lipids in sedimentary rocks document their participation in marine biogeochemical cycles for >100 million years.

Beyond PEGylation: Archaeal Lipids for Long‐Circulating Liposomes

open access: yesAdvanced NanoBiomed Research
The growing concerns regarding the immunogenicity of polyethylene glycol (PEG) have prompted the search for alternative excipients that can prolong circulation in parenteral drug delivery.

Subsurface Production of Marine Derived Bacterial Tetraether Lipids: Implications for Paleoceanographic Reconstruction

open access: yesGeophysical Research Letters
Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are widely used as paleoclimate proxies on land, yet their origin in marine environments remains incompletely constrained.

Planktonic Archaeal Ether Lipid Origins in Surface Waters of the North Pacific Subtropical Gyre

open access: yesFrontiers 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 ...

Application of microbial membrane tetraether lipids in speleothems

open access: yesFrontiers 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 influence of near-surface sediment hydrothermalism on the TEX86 tetraether-lipid-based proxy and a new correction for ocean bottom lipid overprinting [PDF]

open access: yesBiogeosciences, 2022
The diversity and relative abundances of tetraether lipids produced by archaea and bacteria in soils and sediments are increasingly used to assess environmental change.

Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 83-102., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Functionalized Membrane Domains: An Ancestral Feature of Archaea?

open access: yesFrontiers in Microbiology, 2020
Bacteria and Eukarya organize their plasma membrane spatially into domains of distinct functions. Due to the uniqueness of their lipids, membrane functionalization in Archaea remains a debated area. A novel membrane ultrastructure predicts that monolayer

First Isolation and Structure Elucidation of GDNT‐β‐Glu – Tetraether Lipid Fragment from Archaeal Sulfolobus Strains

open access: yesChemistryOpen, 2021
Due to their special chemical structure, tetraether lipids (TEL) represent essential elements of archaeal membranes, providing these organisms with extraordinary properties.
