Abstract
A viscous extracellular polysaccharide produced by Lactobacillus helveticus K16 has been investigated. Sugar and methylation analysis, H-1 and C-13 NM R spectroscopy revealed that the polysaccharide is composed of a hexasaccha ride repeating unit. The sequence of sugar residues was determined by use o f two-dimensional nuclear Overhauser effect spectroscopy and heteronuclear multiple bond connectivity experiments. The structure of the repeating unit of the exopolysaccharide from L. helveticus K16 is as follows: [GRAPHICS] (C) 2000 Elsevier Science Ltd. All rights reserved.
