Structure of the extracellular polysaccharide from slime-forming Lactococcus lactis subsp. cremoris SBT 0495.
The extracellular polysaccharide obtained from slime-forming Lactococcus lactis subsp. cremoris SBT 0495 is composed of D-glucose, D-galactose, L-rhamnose, and phosphate. Methylation analysis of the native and dephosphorylated polysaccharides provided information on the linkage of the sugar residues and the location of the phosphate group. N.m.r. spectroscopy confirmed the structure of the polysaccharide, which is assigned the following repeating-unit: [formula: see text]
