✦ Synopsis
A method For the determination of the composition of the extracellular polysaccharides of some soil bacteria by gas chromatography was worked out, Monosaccharides originating from the hydrolysis of polysaccharides were separated as trimethylsilyl derivatives. In addition to the main components, cc-and P-D-glucose, D-galactose and D-mannose, other hexoses and pentoses, D-fructose, 6-deoxy-L-mannose, D-ribose, D-xylose and uranic acids, i.e. D-glucuronic, D-gahCtUrOniC and Dmannuronic acids, could be detected in the extracellular polysaccharide. Composition of the extracellular polysaccharide was determined in several species of soil bacteria, including Achromobacter deficatulum, Pseudomonas dcsmolyticum, Xanthomonas phaseoli var. fuscans and Azotobacter chroococcum.

A sensitive method for the identification of polysaccharides in pharmaceuticals is described. Polysaccharides are isolated by gel filtration and subsequently hydrolysed. The monomeric carbohydrates obtained are transformed into oxime-trimethylsilyl derivatives and analysed by capillary gas chromatog
