β¦ Synopsis
In continuation of our studies of the surface polysaccharides produced by reference strains of Serratia marcescens, we have isolated the lipopolysaccharide of the 015 strain C.D.C. 4523-60 (yield, 18% of the cell walls). The neutral monosaccharide composition (expressed as percentages of the total peak area on g.1.c. of the alditol acetates) was: rhamnose, 37.6; mannose, 22.4; glucose, 21.3; galactose, 1.6; D-glycero-D-manno-heptose, 3.8; L-glycero-D-manno-heptose, 13.2%.

Both a neutral and an acidic polymer have been isolated from a lipopolysaccharide extract of the reference strain for Serratia marcescens serogroup O22. The neutral polymer has a linear structure with the repeating unit shown. The same tetrasaccharide unit also forms the backbone of the branched neu
The structure of the acidic polysaccharide from Serratia marcescens serogroup O1 has been investigated. NMR spectroscopy together with sugar and methylation analysis have been used as well as a uronic acid degradation. The polysaccharide consists of pentasaccharide repeating units having the followi
