Structure of surface polysaccharides from Aeromonas sp AMG272, a plant-growth promoting rhizobacterium isolated from rice rhizosphere
Aeromonas sp. AMG272 is a Gram-negative bacterium that has been isolated from agricultural soil and studied for its plant growth-promoting activities. Structures of the O-specific polysaccharide chain of the AMG272 lipopolysaccharide and its capsular polysaccharide were elucidated using GLC-MS and N...

| Sumario: | Aeromonas sp. AMG272 is a Gram-negative bacterium that has been isolated from agricultural soil and studied for its plant growth-promoting activities. Structures of the O-specific polysaccharide chain of the AMG272 lipopolysaccharide and its capsular polysaccharide were elucidated using GLC-MS and NMR spectroscopy. The structure of the O-specific polysaccharide, →4)-α-L-Rhap-(1→3)-β-D-GlcpNAc-(1→, has been found in other Aeromonas strains and related bacteria, whereas the structure of the capsular polysaccharide has not been reported before: →6)[β-D-Fucp3NAc4Ac-(1→3)]-α-D-GlcpNAc-(1→4)-α-D-Galp-(1→3)-α-D-GalpNAc-(1→4)-α-D-Galp-(1→. |
