Structure of the O-polysaccharide of Photorhabdus temperata subsp. temperata XlNachT containing a novel branched monosaccharide, 3,6-dideoxy-4-C-[(S)-1,2-dihydroxyethyl]-d-xylo-hexose

- O-Polysaccharide was isolated from an entomopathogenic bacterium Photorhabdus temperata.
- Structure of the O-polysaccharide was established by NMR and chemical approaches.
- A novel branched C8 monosaccharide was identified as a polysaccharide component.
