Asian Winter Monsoon Imprint on the Water Column Structure at the Northern South China Sea Coast
Frontiers in Earth Science, 2021 Coastal regions of the northern South China Sea (SCS) strongly interact with the Asian monsoon circulation (AMC). Thus, variations of sea surface temperature (SST) here are newly suggested to document AMC changes in an effective manner, but additional ...

Provenance of tetraether membrane lipids in a large temperate lake (Loch Lomond, UK): implications for glycerol dialkyl glycerol tetraether (GDGT)-based palaeothermometry [PDF]
Biogeosciences, 2014 The application of glycerol dialkyl glycerol tetraether (GDGT)-based palaeoenvironmental proxies, such as the branched vs. isoprenoidal tetratether (BIT) index, TEX86 and the MBT–CBT palaeothermometer, has lately been expanded to lacustrine sediments ...

Structure-Function Relationships in Pure Archaeal Bipolar Tetraether Lipids [PDF]
, 2023 Archaea, the third fundamental domain of life are distinguished from bacteria and eukaryotes due to the presence of unique lipids in their cell membranes.

Frontiers in Earth Science, 2021 Hadal trenches have higher microbial carbon turnover rates as compared to adjacent abyssal plains. However, the source of organic carbon in the trench remains enigmatic. In this study, we show that a fraction of organic carbon is possibly derived in situ

Cytoplasmic Lipid Membrane Biogenesis in Prokaryotes: From Soluble Lipid Building Blocks to a Dynamic and Functional Boundary Layer [PDF]
ChembiochemLipid membranes are fundamental to all prokaryotic life. Besides acting as barrier, by orienting as hydrophobic bilayer, lipids are involved in a wide variety of other cellular processes. As a consequence, prokaryotic membranes are dynamic entities that switch their lipid composition as required; a process that requires tight interplay with the lipid ...

Life, 2015 The functionality of the plasma membrane is essential for all organisms. Adaption to high growth temperatures imposes challenges and Bacteria, Eukarya, and Archaea have developed several mechanisms to cope with these.

Membrane homeoviscous adaptation in the piezo-hyperthermophilic archaeon Thermococcus barophilus
Frontiers in Microbiology, 2015 The archaeon Thermococcus barophilus, one of the most extreme members of hyperthermophilic piezophiles known thus far, is able to grow at temperatures up to 103°C and pressures up to 80MPa. We analyzed the membrane lipids of T. barophilus by HPLC-MS as a

A laboratory experiment on the behaviour of soil-derived core and intact polar GDGTs in aquatic environments [PDF]
Biogeosciences, 2015 We have performed incubation experiments in order to examine the behaviour of soil-derived branched glycerol dialkyl glycerol tetraether (brGDGT) membrane lipids upon entering an aquatic environment and to evaluate the processes that potentially take ...

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 ...

Frontiers in Microbiology, 2020 The influence of oxidation-reduction (redox) potential on the expression of biomolecules is a topic of ongoing exploration in geobiology. In this study, we investigate the novel possibility that structures and compositions of lipids produced by microbial
