โœฆ Synopsis

Partially acetylated acidic glucomannans have been isolated from three strains of Serrutia murcescens serogroup 014 and one strain of the cross-reacting serogroup 06. Degradative and spectroscopic studies established that the polysaccharides have branched tetrasaccharide repeating-units of the structure shown. Individual polymers may vary in the extent or location of 0-acetylation, and in the extent of undefined heterogeneity apparently associated with the glucosyluronic acid residues. Although the polymers were obtained from lipopolysaccharide extracts, there are indications of a (micro)capsular origin. The acidic glucomannans may constitute a common antigen which defines the 014-06 complex of S. murcescens. o-D-GIcPA 1 t -4)-a-o-Mo~p-(l'3)-a-o-Glcp-(l'3)-/3-~-Glc~-(l-*Presented, in part, at the XIIth International Carbohydrate Symposium,
