“…However, there is no evidence from abundant culture experiments that the monounsaturated archaeol will be directly biosynthesized. The only previously reported unsaturated diether is bis-O-geranylglyceroldiether (IV; Sulfolobus solfataricus, De Rosa et al, 1983; Methanopyrus kandleri, Sprott et al, 1997), which is significantly different than the compound observed here. Moreover, in the brine sample, ␦ 13 C values of hydroxyarchaeol and monounsaturated archaeol are similar (Ϫ87 and Ϫ82‰, respectively) and depleted relative to archaeol (Ϫ63‰), suggesting a common origin.…”

Abstract-We investigated the distributions and ␦ 13 C values of biomarkers for Archaea associated with anaerobic methane oxidation in disparate settings throughout two Eastern Mediterranean mud dome fields. All major classes of archaeal lipids are present in the studied sediments, including isoprenoid glycerol diethers, isoprenoid glycerol dialkyl glycerol tetraethers, and irregular isoprenoid hydrocarbons. Of the compounds present, many, including a novel glycerol tetraether and sn-3-hydroxyarchaeol, have not been previously reported for settings in which methane oxidation is presumed to occur. Archaeal lipids are depleted in 13 C, indicating that the Archaea from which they derive are either directly or indirectly involved with methane consumption. The most widespread archaeal lipids are archaeol, PMI, and glycerol tetraethers, and these compounds are present at all active sites. However, archaeal lipid abundances and distributions are highly variable; ratios of crocetane, PMI, and hydroxyarchaeol relative to archaeol vary from 0 to 6.5, from 0 to 2, and from 0 to 1, respectively. These results suggest that archaeal communities differ amongst the sites examined. In addition, carbon isotopic variability amongst archaeal biomarkers in a given mud breccia can be as large as 24 ‰, suggesting that even at single sites multiple archaeal species perform or are supported by anaerobic methane oxidation.

“…They can represent the main constituents of archaeal membranes and can contain 0-8 cyclopentane rings (De Rosa et al, 1983;Langworthy, 1985;De Rosa and Gambacorta, 1988). In the carbonate crusts and mud breccias GDGTs prevail over all other identified archaeal lipids.…”

Biomarker and 16S rDNA evidence for anaerobic oxidation of methane and related carbonate precipitation in deep-sea mud volcanoes of the Sorokin Trough, Black Sea

Many mud volcanoes were recently discovered in the euxinic bottom waters of the Sorokin Trough (NE Black Sea). Three of them, i.e., NIOZ, Odessa, and Kazakov, were selected for a detailed biogeochemical investigation. Four methane-related carbonate crusts covered with microbial mats, and sediments (dmud brecciaT) from these mud volcanoes were collected during the 11th Training-Through-Research cruise (TTR-11) in 2001, the first finding of methanotrophic microbial mats associated with authigenic carbonates in the deep Black Sea. We measured the concentrations and d13 C values of methane and specific archaeal and bacterial lipids, and determined archaeal and bacterial 16S rRNA gene sequences. The d 13 C of the microbial lipids reflected the carbon isotopic values of the methane, indicating that methane was the main carbon source for microorganisms inducing carbonate formation. Anaerobic oxidation of methane (AOM) in these settings was performed by archaea affiliated with the so-called ANME-1 group. None of the identified archaeal sequences were closely related to known methanogens. The combined 16S rRNA gene sequence and biomarker data revealed a distinct difference in archaeal assemblage between the carbonate crusts and mud breccias. Besides gene sequences of sulfate-reducing bacteria, DNA analysis of bacterial communities revealed a diversity of bacteria with apparent contrasting metabolic properties. The methane utilization via AOM processes was detected in the uppermost sediments where it subsequently induces authigenic carbonate precipitation most probably below seafloor. The results of integrated biomarker and 16S rRNA gene study reveal a crucial role of AOM processes in formation of authigenic carbonates in methane seep environments. D

“…The second series has a structural organization similar to that of GDGTs, but a more complex polyol with nine carbon atoms replaces one of the glycerols. By analogy this series is named GDNTs (glycerol dialkyl nonitol tetraethers; De Rosa et al, 1983). The uncyclized GDGT a (Fig.…”

SummaryCore and complex lipids of several new hyperthermophilic archaeal isolates were analyzed. The organisms belong to the Sulfolobales,Archaeoglobus, Pyrobaculum, and Methanococcus. A detailed structural investigation of complex lipids of Pyrobaculum species is reported. The different lipid structures are of help for a rapid and simple phylogenetic classification of the new isolates. They are in agreement with the classification based on other features.
