โœฆ Synopsis


The composition of the polysaccharide moieties of the lipopolysaccharide (LPS) fraction of Pseudomonas caryophylli is described. Two homopolysaccharide chains, the major one built up of (1 ~ 7)-linked a-caryophyllose [3,6,10-trideoxy-4-C-(D-glycero-l-hydroxyethyl)-o-erythro-Dgulo-decose] residues and the minor one made up of (1 ~ 7)-linked fl-caryose (4,8-cyclo-3,9-dideoxy-L-erythro-D-ido-nonose) residues, were identified in the LPS fraction. In addition, experimental evidence of a third polysaccharide fraction mainly composed of heptose and glucose is also reported. The structural analysis was performed by chemical and spectroscopic methods.
