Lactobacillus helveticus Lh59 secretes an exopolysaccharide that is identical to the one produced by Lactobacillus helveticus TN-4, a presumed spontaneous mutant of Lactobacillus helveticus TY1--2.

Abstract excerpt

Lactobacillus helveticus Lh59 produces a high-molecular-mass exopolysaccharide (> or = 2 x 10(6) Da) when cultured in skimmed milk. Compositional analysis, methylation analysis and NMR experiments (1H and 13C) recorded from the native polysaccharide as well as from oligosaccharides released by partial acid hydrolysis, allowed the complete structural determination of this polysaccharide, which consists of the...
