✦ Synopsis

Batch-culture growth of Zoogfoea rumigeru 115 in a defined medium produced a weakly acidic polysaccharide containing glucose and galactose residues, and (Qpyruvic acetal groups. Analytical results indicated that the polysaccharide does not have a simple repeating-unit.

Mainly with the aid of Smith degradation of the native polysaccharide and oxidation and subsequent ,S-elimination of the methylated and then depyruvylated polysaccharide, some structural features of the polysaccharide were identified.
