The major phospholipids of Halorubrum lacusprofundi grown at 25 1C were archaeol phosphatidylglycerol, archaeol … phosphatidylglycerylsulphate and archaeol phosphatidylglycerylphosphate methyl ester.Glycolipids included a monoglycosyl archaeol and the sulphate ester of a diglycosyl archaeol.
Improved testing and remediation procedures for sites … contaminated with petroleum hydrocarbons are a priority … in remote cold regions such as Antarctica, where costs are … higher and remediation times are longer.
A common technique for comparing the in situ microbial potential for mineralisation of petroleum hydrocarbons in different environments or under different remediation strategies, is by use of radiolabelled tracer studies.
Two novel glycolipids, docosanyl 3-O-methyl-alpha - rhamnopyranoside and docosanyl 3-O-methylxylopyranoside, were identified as the most abundant GC-amenable components of extracts of sediments of Ace Lake, an Antarctic meromictic lake.
Surface sediments (0-25 cm) from Ace Lake (eastern Antarctica), a saline euxinic lake, were analyzed to study the early incorporation of reduced inorganic sulfur species into organic matter. The apolar fractions were shown to consist predominantly of dimeric (poly)sulfide linked C-27-C-29 steroids.
