Characterization of novel long-chain 1,2-diols in Thermus species and demonstration that Thermus strains contain both glycerol-linked and diol-linked glycolipids

A study which was aimed at characterizing new Thermus strains and confirming the presence of glycerol-linked and diol-linked glycolipids within these strains was conducted. The methods used were extraction and purification of polar lipids, hydrolysis and analysis of glycolipids, preparation of fatty acid methyl esters (FAMEs) and derivatization. Results showed that partial structures of intact diol-containing lipids were present in the bacteria and some Thermus strains contain a mixture of diol- and glycerol-based glycolipids which were not present in the Thermomicrobium roseum.
