✦ Synopsis

The exopolysaccharide produced by Lactobacillus helveticus 766 in skimmed milk was found to be composed of D-glucose and D-galactose in a molar ratio of 2:1. Linkage analysis and 1D/2D NMR studies (tH and 13C) performed on the native polysaccharide, and on oligosaccharides obtained from a partial acid hydrolysate, showed the polysaccharide to consist of hexasaccharide repeating units with the following structure:

## Abstract A method is described for constructing a conformational model in water of a heteropolysaccharide built up from repeating units, and is applied to the exopolysaccharide produced by __Lactobacillus helveticus__ 766. The molecular modeling method is based on energy minima, obtained from mo

A. beijerinckii strain B-1615 produced two acidic exopolysaccharides in the ratio approximately 9:1. The minor polysaccharide contained mannuronic and guluronic acids in the ratio 2.3:1 and is a bacterial alginate. The major polysaccharide consisted of D-galactose, L-rhamnose, and pyruvic acid in th
