Structures of the O-Specific Polysaccharides from Yokenella regensburgei (Koserella trabulsii) Strains PCM 2476, 2477, 2478, and 2494: High-Resolution Magic-Angle Spinning NMR Investigation of the O-Specific Polysaccharides in Native Lipopolysaccharides and Directly on the Surface of Living Bacteria

The structures of the carbohydrate O-specific side-chain moiety of the lipopolysaccharides (LPS) of Yokenella regensburgei, strains PCM 2476, 2477, 2478, and 2494, have been investigated by 1H and 13C NMR, fast atom bombardment tandem mass spectrometry (FAB-MSMS), matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry, methylation analysis, partial acid hydrolysis, and immunological methods. It was concluded...
