The Gram-negative bacterium under study belongs to the genus Kaistella. It was isolated from a soil sample of the Haian Island in China, and it produces a lipophilic polysaccharide characterised by a branched hexasaccharide repeating unit, counting four 6-deoxy-a-L-mannose (Rha) residues, one 2-acetamido-2-deoxy-b-D-glucose (GlcNAc) and a 2-acetamido-2,6-dideoxy-b-D-galactose (FucNAc) unit. The structure of the repeating unit, assigned through 2D-NMR spectroscopy, is herein reported for the first time:

Abstract
The Gram-negative bacterium under study belongs to the genus Kaistella. It was isolated from a soil sample of the Haian Island in China, and it produces a lipophilic polysaccharide characterised by a branched hexasaccharide repeating unit, counting four 6-deoxy-a-L-mannose (Rha) residues, one 2-acetamido-2-deoxy-b-D-glucose (GlcNAc) and a 2-acetamido-2,6-dideoxy-b-D-galactose (FucNAc) unit. The structure of the repeating unit, assigned through 2D-NMR spectroscopy, is herein reported for the first time:| File | Dimensione | Formato | |
