Notes:
Three kinds of capsular polysaccharide (CP) were found to be produced by Burkholderia pseudomallei. When the bacterium was grown with the medium without glycerol, CP-1a and CP-1b were produced. CP-1a was mainly 1,4-linked glucan and CP-1b was identified as a polymer composed of galactose and 3-deoxy-d-manno-octulosonic acid, whose chemical structure was recently reported by other laboratories. When the bacterium was grown with the medium containing 5% glycerol, CP-2 was synthesized. CP-2 contained galactose, rhamnose, mannose, glucose and a uronic acid in a ratio of approximately 3:1:0.3:1:1. Methylation analysis of the purified polysaccharides demonstrated that the two acidic polysaccharides, CP-1b and CP-2, shared no common structure, indicating that CP-2 was an acidic capsular polysaccharide whose chemical characters were not reported previously.
