英文摘要An immunoactive extracelluar polysaccharide was isolated from Pseudoalteromonas sp. S-15-13, a bacterium screened from Antarctic sea-ice. In order to accurately define the structure of the Antarctic bacterial EPSs and to relate these findings to the function of these molecules in the natural environment, purification and structural analysis of S-15-13 EPSs was carried out. Exopolysaccharide fractions were extracted and were purified by DEAE-Sephadex A-50 ion-exchange and Sephadex G-100 gel chromatography to give EPS-II. The EPS-II was eluted as a single peak in HPLC analysis, indicating that the homogeneity and purity of EPS-II were suited to the structural analysis. The molecular weight of the EPS-II was determined as 62000 by the HPLC method. Sugar composition analysis, methylation analysis and one-dimensional and two-dimensional NMR spectroscopies reveal that the main structure of EPS-II was a 1 2 linking mannan with fewer 1 2, 6-linking branch, a new extracelluar polysaccharide from Antarctic bacterium.
