A polysaccharide produced by a mucoid strain of Moraxella nonliquefaciens with a 2-acetamido-2-deoxy-5-O-(3-deoxy-beta-D-manno-octulopyranosyl)-beta-D- galactopyranosyl repeating unit.
A capsular polysaccharide, isolated from the mucoid Moraxella nonliquefaciens strain 3828/60, has been investigated by component analyses, periodate oxidation, methylation analyses, mass spectrometry, 1H and 13C NMR spectroscopy, and hydrolysis to give a disaccharide that was isolated and characterised. The results showed that the polysaccharide has the repeating unit-->3)-beta-D- GalpNAc-(1-->5)-beta-Kdo p-(2-->, with approximately 40% of O-8 of Kdo being acetylated.
