Solvent extracted sediments from El Junco Lake, Galapagos were sequentially hydrolyzed with base and acid. Some of the “bound” lipids thus generated were not detected among the “free” lipids obtained from the initial solvent extract of the fr

Lipid biomarkers in lacustrine sediments provide valuable information about lake history and environmental change. Here we report the occurrence of a unique set of lipid biomarkers from a freshwater crater lake, El Junco, in the Galapagos. In additio

The thermal reactivity of organic matter in source rocks is usually kinetically represented by a set of parallel and independent first order reactions. This approach assumes that only defunctionalization reactions take place upon thermal decompositio

The lipids of three gram-negative bacteria, Acineto-bacter calcoaceticus, Marinobacter aquaeolei, and Pseudomonas oleovorans grown on mineral media supplemented with ammonium acetate or hydrocarbons, were isolated, purified, and their structures dete

Batch cultures of the hydrocarbon-rich alga Botryococcus braunii, Kutz. (axenic strains, non-axenic strains, associations with selected microorganisms) were examined with regard to total biomass and hydrocarbons at the onset of the stationary phase.

The lipids of the gram-negative marine bacterium Marinobacter hydrocarbonoclasticus, cultivated in synthetic seawater supplemented with 1-chlorooctadecane as sole source of carbon, were isolated, purified, and their structures determined. Three pools

Four new tetraterpenoid ethers, lycopanerols I-L (5-8), were isolated from a culture of a strain of the green microalga Botryococcus braunii (L race). The structures were determined by means of spectral analyses and chemical degradation. The relative

Two high molecular weight ether lipids, C151 and C153 lycopanerols H, have been isolated from the lipid extract of a strain of the green microalga Botryococcus braunii. These new compounds arise from the linkage via ether bridges of tetraterpenoid, n

A novel hydrocarbon 3,7,18,22-tetramethylsqualane has been identified in extracts from the Maniguin-2 well on Maniguin Island, Philippines, the Duri oil from Sumatra, Indonesia and the Maoming Oil Shale from China. A related hydrocarbon, tentatively

The lipids of the Gram-negative marine bacterium Marinobacter hydrocarbonoclasticus , cultivated in synthetic seawater on a single carbon source, acetate or n -icosane, were isolated, purified and their structures determined. Three different pools of
