Structural studies of an acidic galactoglucomannan from the O3 reference strain (C.D.C. 863-57) of Serratia marcescens.
A partially acetylated acidic galactoglucomannan has been isolated from the lipopolysaccharide of the O3 reference strain (C.D.C. 863-57) of Serratia marcescens. By means of n.m.r. spectroscopy, methylation analysis, and degradative studies, the polymer was found to have the branched pentasaccharide repeating-unit shown. The position(s) of partial acetylation were not determined. Although the polymer is believed to confer O specificity on the parent organism, it is probably not an integral component of the lipopolysaccharide. (Formula: see text).
