title: [Physico-chemical properties and heterogeneity of Alcaligenes faecalis polysaccharide].
abstract: Two species of O-antigenic molecules with following sedimentation characteristics S(o)20, W 1,25.10(-13) S, D(o)20, W 9,7.10(-7) cm2/s, M 8000 and S(o)20, W 2,5.10(-13) S, D(o)20, W 5.10(-7) cm2/s, M 23,000-30,000 were detected in the cell wall of the strain Alcaligenes faecalis, a representative species of conditionally pathogenic microorganisms with unidentified taxonomic position. "Light" and "heavy" types of molecules have a lipopolysaccharide nature and show no differences in the monosaccharide composition of the polysaccharide moiety, structural organization of O-chain, or lipid A fatty-acid composition.
