NMR spectra were obtained using an Avance DPX-500 NMRspectrometer (Bruker, Germany) resonating at 75.5 MHz at 35◦C.The concentration of the samples was 5–20 mg of polysaccha-ride/mL of D2O for 1D and 2D experiments.GLC–MS of alditol acetate derivatives was performed using aHewlett-Packard 6850 (USA) chromatograph equipped with HP-5MS capillary column (30 m x 0.2 mm) with a temperature gradientof 150 → 230◦C at 3◦C min−1.MALDI-TOF mass spectra were recorded with an Ultra FlexIII MALDI-TOF/TOF mass spectrometer (Bruker, Germany) with aSmartBeam laser (355 nm), reflector and potential LIFT tandemmodes of operation.ESIMS/MS spectra were recorded with an ESI Q-TOF massspectrometer (Agilent 6510 LC Q-TOF, USA) with a dualelectrospray-ionization source.
