摘要：

Lipopolysaccharide was obtained by phenol-water extraction from dried bacterial cells of Azospirillum brasilense type strain Sp7. Mild acid hydrolysis of the lipopolysaccharide followed by GPC on Sephadex G-50 resulted in a polysaccharide mixture, which was studied by composition and methylation analyses, Smith degradation and H-1 and C-13 NMR spectroscopy. The following polysaccharide structures were established, where italics indicate a non-stoichiometric (similar to 40%) 2-O-methylation of L-rhamnose. [GRAPHICS] (C) 2013 Elsevier Ltd.
