Structure of an extracellular mannosylated cellulose produced by a mutant strain of Xanthomonas campestris.
Structural studies were performed in two atypical polysaccharides, PS-1 and PS-2 isolated from the broth of a Tn5 mutant strain of Xanthomonas campestris. Sugar composition, methylation and nuclear magnetic resonance analyses were determined. PS-1 is composed by repeating trisaccharide units containing D-glucose, D-mannose and having the structure. carbohydrate sequence [see text]. Preliminary studies on the PS-2 show a polymer composed in a large extent of rhamnose. Unexpectedly, this polysaccharide is soluble in alcoholic solutions.
