Lipopolysaccharides of Acidiphilium cryptum and Acidiphilium symbioticum , the acidophilic heterotrophs of sulfidic mine environments, contain rhamnose, glucose, galactose and mannose. Molar ratios of the neutral sugars differ in these two lipopolysaccharide preparations. 3‐Deoxy‐d‐manno‐2‐octulosonic acid is present in both the lipopolysaccharides, and galactosamine was the only amino sugar detected. 3‐Hydroxytetradecanoic acid was found to be the major fatty acid component along with minute amounts of decanoic and dodecanoic acids. Deoxycholate‐PAGE electrophoresis revealed the presence of short sugar chains and unsubstituted cores. The implications of these findings are discussed in relation to acidiphilicity and systematics of Acidiphilium species.
