Distribution of Complex and Core Lipids within New Hyperthermophilic Members of the Archaea Domain

Abstract

Core 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.
