Abstract :
Mild acid degradation of the lipopolysaccharide of Citrobacter youngae O9, strain PCM 1538 released a homopolysaccharide of 4-acetamido-4,6-dideoxy-d-mannose (d-Rha4NAc, N-acetyl-d-perosamine). Studies by methylation analysis and 1H and 13C NMR spectroscopy, using two-dimensional 1H,1H COSY, TOCSY, NOESY and H-detected 1H,13C HSQC experiments showed the presence of two structurally different polysaccharides consisting of the following units:→2)-α-d-Rhap4NAc-(1→and→3)-α-d-Rhap4NAc-(1→3)-β-d-Rhap4NAc-(1→
