Abstract
The halophilic Archaeon Haloferax mediterranei exudes into the growth medium a high molecular weight sulfated polysaccharide. The structure of the repeating unit of this polymer was determined by a combination of glycose, methylation. and sulfate analysis, periodate oxidation, an d 1D and 2D NMR spectroscopic analysis of the native and periodate-oxi dised/reduced polysaccharides. The location of the sulfate group was e stablished from the H-1 and C-13 NMR data. The structure of the repeat ing unit of the polysaccharide may be written as 6)-alpha-D-Manp-(1-4) -beta-D-GlcpNAcA-3-O-SO3--(1- (C) 1996 Elsevier Science Ltd.
