Abstract
The extracellular polysaccharide produced by Lactobacillus rhamnosus strain C83 was found to be composed of D-glucose and D-galactose in a molar ratio of 2.3. The primary structure of the polysaccharide was shown by sugar ana lysis, methylation analysis, FARMS, partial acid hydrolysis and nuclear mag netic resonance (NMR) spectroscopy to consist of a pentasaccharide repeatin g unit having the following structure: --> 3)-alpha-D-Glcp-(1 --> 2)-beta-D-Galf-(1 --> 6)-alpha-d-Glcp-(1 --> 3)- beta-D-Galf-(1 --> (C) 1998 Elsevier Science Ltd.
