RESUMO
A phosphorylated 2-keto-3-deoxyoctonic acid (KDO) was released from the lipopolysaccharides of Vibrio cholerae Ogawa and Inaba after strong acid hydrolysis. The phosphorylated KDO was identified by gas-liquid chromatography and mass spectrometry after reduction and permethylation as KDO-5-phosphate and an isomer of it being phosphorylated at position 7 or 8. After treatment with alkaline phosphatase, KDO was detected by gas-liquid chromatography and mass spectrometry. It was indistinguishable from authentic 2-keto-3-deoxy-D-manno-octonic acid.
