Am. Winn et Sg. Wilkinson, STRUCTURE OF THE O20 ANTIGEN OF STENOTROPHOMONAS (XANTHOMONAS OR PSEUDOMONAS) MALTOPHILIA, Carbohydrate research, 294, 1996, pp. 109-115
The O-antigen polymer recovered from the reference strain for Stenotro
phomonas (Xanthomonas or Pseudomonas) maltophilia serogroup O20, by mi
ld acid hydrolysis of the lipopolysaccharide, was found to contain D-r
hamnose and D-mannose. By means of chemical degradations and NMR studi
es, the repeating-unit of the polymer was deduced to be a linear tetra
saccharide with the structure shown. ap-(1-->2)-alpha-D-Rhap-(1-->2)-a
