Abstract
The moderately halophilic strain Salinivibrio sp. EG9S8QL was isolated among 11 halophilic strains from saline mud (Emisal Salt Company, Lake Qarun, Fayoum, Egypt). The lipopolysaccharide was extracted from dried cells of Salinivibrio sp. EG9S8QL by the phenol–water procedure. The OPS was obtained by mild acid hydrolysis of the lipopolysaccharide and was studied by sugar analysis along with 1H and 13C NMR spectroscopy, including 1H,1H COSY, TOCSY, ROESY, 1H,13C HSQC, and HMBC experiments. The OPS was found to be composed of linear tetrasaccharide repeating units of the following structure: →2)-β-Manp4Lac-(1→3)-α-ManpNAc-(1→3)-β-Rhap-(1→4)-α-GlcpNAc-(1→, where Manp4Lac is 4-O-[1-carboxyethyl]mannose.

Abstract
The primary structure of the acidic capsular antigen produced by E. coli K84 was shown by glycose and methylation analysis, and by 1D and 2D 1H and 13C NMR studies of the polysaccharide and an oligosaccharide produced by lithium-ethylenediamine degradation of the polysaccharide, to be comprised of linear hexasaccharide repeating units of the following structure: -->4)alpha-D-GaI pA-(1-->3)-alpha-D-Man p-(1-->4)-beta-D-GIc p-(1-->3)-alpha- D-Glc pNAc-(1-->2)-beta-D-Man p-(1-->3)-beta-D-Man pNAc-(1-->.
