Structural studies of an acidic galactoglucomannan from the O15 reference strain (C.D.C. 4523-60) of Serratia marcescens.
Both neutral and acidic polymers have been isolated from the lipopolysaccharide extract of the reference strain (C.D.C. 4523-60) for Serratia marcescens serogroup O15. By means of n.m.r. spectroscopy, methylation analysis, and studies of degradation products, the acidic polysaccharide was shown to have a branched pentasaccharide repeating-unit with the following structure.
