Abstract
Two strains of the gliding phototrophic bacterium Chloroflexus aurantiacus were investigated for the presence of lipopolysaccharide (LPS). With both strains, all fractions of hot phenol-water extracts and the extracted cell residues from whole cells or cell homogenates were found to be free from characteristic LPS constituents, such as 3-hydroxy fatty acids, 2-keto-3-deoxyoctonate, heptoses, or O-chain sugars. Phenolchloroform-petroleum ether extracts were also free from precipitable LPS. A lipid A fraction could not be obtained, and there was no hint for glucosamine as a possible lipid A backbone amino sugar. Absence of LPS was confirmed by sodium deoxycholate gel electrophoresis.
