摘要：

Lactobacillus delbrueckii subsp. bulgaricus NCFB2074 when grown in skimmed milk secretes a highly branched exopolysaccharide. The exopolysaccharide has a heptasaccharide repeat unit and is composed of glucose and galactose in the molar ratio 3:4. Using chemical techniques and ID and 2D NMR spectroscopy the polysaccharide has been shown to possess the following repeat unit structure: (c) 2005 Elsevier Ltd. All rights reserved.
