Distribution of tetraether lipids in agricultural soils – differentiation between paddy and upland management [PDF]
Biogeosciences, 2016 Rice paddies constitute almost a fifth of global cropland and provide more than half of the world's population with staple food. At the same time, they are a major source of methane and therewith significantly contribute to the current warming of Earth's

An Adaptation To Life In Acid Through A Novel Mevalonate Pathway. [PDF]
, 2016 Extreme acidophiles are capable of growth at pH values near zero. Sustaining life in acidic environments requires extensive adaptations of membranes, proton pumps, and DNA repair mechanisms.

Constraints in the application of the Branched and Isoprenoid Tetraether index as a terrestrial input proxy [PDF]
, 2011 Determination of the relative inputs of aquatic autochthonous and terrestrial allochthonous organic matter into marine and lacustrine environments is essential to understanding the global carbon budget.

Assessing branched tetraether lipids as tracers of soil organic carbon transport through the Carminowe Creek catchment (southwest England) [PDF]
Biogeosciences, 2020 Soils represent the largest reservoir of organic carbon (OC) on land. Upon mobilization, this OC is either returned to the atmosphere as carbon dioxide (CO2) or transported and ultimately locked into (marine) sediments, where it will act as a long-term ...

Energy flux controls tetraether lipid cyclization in Sulfolobus acidocaldarius [PDF]
Environmental Microbiology, 2019 Summary Microorganisms regulate the composition of their membranes in response to environmental cues. Many Archaea maintain the fluidity and permeability of their membranes by adjusting the number of cyclic moieties within the cores of their glycerol dibiphytanyl glycerol tetraether (GDGT) lipids.

Constraints on the sources of branched tetraether membrane lipids in distal marine sediments [PDF]
, 2014 Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are membrane lipids produced by soil bacteria and occur in near coastal marine sediments as a result of soil organic matter input.

Biosynthesis of archaeal membrane ether lipids
Frontiers in Microbiology, 2014 A vital function of the cell membrane in all living organism is to maintain the membrane permeability barrier and fluidity. The composition of the phospholipid bilayer is distinct in archaea when compared to bacteria and eukarya.

Archaeosomes and Tetraether Lipid Liposome
Pharmaceutical Sciences and Research, 2012 Archaea have phytanyl ether lipids which is one of the characteristics that separates them from bacteria and eukaryotes. Some archaea have also unique membrane spanning tetrae- ther lipids (T EL); in Sulfolobus and Ihermoplasma species these TELmake up the majority of total membrane lipids.

Benthic archaea as potential sources of tetraether membrane lipids in sediments across an oxygen minimum zone [PDF]
Biogeosciences, 2018 Benthic archaea comprise a significant part of the total prokaryotic biomass in marine sediments. Recent genomic surveys suggest they are largely involved in anaerobic processing of organic matter, but the distribution and abundance of these archaeal ...
