The structures of glycolipids isolated from the highly thermophilic bacterium Thermus thermophilus Samu-SA1.
Thermophiles constitute a class of microorganisms able to grow at extremely elevated temperatures. Some of these spe-cies are classified as Gram-negative bacteria, because of the presence of an outer membrane in the cell envelope, which is located on the top of a thick murein layer. Unlike typical Gram-negative bacteria, the outer membranes of Thermus species are not composed of lipopolysaccharides but of pecu-liar glycolipids (GL), whose structures seem to be strictly involved in the adaptation to high temperatures. In this work, the complete structures of the major GL components from the cell envelope of the thermophilic bacterium Thermus thermo-philus Samu-SA1 are presented. Protocols conventionally adopted for Gram-negative bacteria were used, and, for the first time, GL from Thermus were analyzed in their native form. Two GL and one phosphoglycolipid (PGL) wer
