The K8 and K54 capsular polysaccharides were isolated from Acinetobacter baumannii BAL 097 and RCH52, respectively, and studied by sugar analysis, partial acid hydrolysis and selective solvolysis with CF3CO2H in the presence of 2-methyl-1-propanol, along with 1D and 2D 1H and 13C NMR spectroscopy. The following structures of related branched tetrasaccharide repeats (K units) of the polysaccharides were established:
