Hydrologic controls on seasonal and inter-annual variability of Congo River particulate organic matter source and reservoir age [PDF]
We present dissolved organic carbon (DOC) concentrations, particulate organic matter (POM) composition (δ13C, δ15N, ∆14C, N/C), and particulate glycerol dialkyl glycerol tetraether (GDGT) distributions from a 34-month time-series near the mouth of the ...

Archaeal Life on Tangkuban Perahu- Sampling and Culture Growth in Indonesian Laboratories
The aim of the expedition to Tangkuban Perahu, West Java was to obtain archaeal samples from the solfatara fields located in Domas crater. This was one of the places, where scientists from the University of Regensburg Germany had formerly isolated ...

Membrane homeoviscous adaptation in the piezo-hyperthermophilic archaeon Thermococcus barophilus
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

Archaeal intact polar lipids in polar waters: a comparison between the Amundsen and Scotia seas [PDF]
The West Antarctic Ice Sheet (WAIS) is one of the largest potential sources of future sea-level rise, with glaciers draining the WAIS thinning at an accelerating rate over the past 40 years.

Gene deletions leading to a reduction in the number of cyclopentane rings in Sulfolobus acidocaldarius tetraether lipids [PDF]
The cell membrane of (hyper)thermophilic archaea, including the thermoacidophile Sulfolobus acidocaldarius, incorporate dibiphytanylglycerol tetraether lipids.

Here, we model a negatively charged lipid vesicle, composed of a mixture of bipolar tetraether and diester (or diether) phospholipid molecules, by a spherical shell that has zero ion permeability.

The abundance and composition of glycerol dibiphytanyl glycerol tetraether (GDGT) and glycerol tribiphytanyl glycerol tetraether (GTGT) lipids were determined as a function of growth phase as a proxy for nutrient availability, the pH of growth medium ...

Planktonic archaea include predominantly Marine Group I Thaumarchaeota (MG I) and Marine Group II Euryarchaeota (MG II), which play important roles in the oceanic carbon cycle. MG I produce specific lipids called isoprenoid glycerol dibiphytanyl glycerol

The dispersal of fluvially discharged and marine, shelf-produced particulate organic matter in the northern Gulf of Mexico [PDF]
Rivers play a key role in the global carbon cycle by transporting terrestrial organic matter (TerrOM) from land to the ocean. Upon burial in marine sediments, this TerrOM may be a significant long-term carbon sink, depending on its composition and ...
