Abstract
Structural studies were performed in two atypical polysaccharides, PS- I and PS-2 isolated from the broth of a Tn5 mutant strain of Xanthomon as campestris. Sugar composition, methylation and nuclear magnetic res onance analyses were determined. PS-1 is composed by repeating trisacc haride units containing D-glucose, D-mannose and having the stucture - ->4)-beta-D-Glcp(1-->4)-(-D-Glcp(1--> 3 up arrow 1 alpha-D-Manp Prelim inary studies on the PS-2 show a polymer composed in a large extent of rhamnose. Unexpectedly, this polysaccharide is soluble in alcoholic s olutions.
