The structure of the exopolysaccharides produced by Streptococcus thermophilus LY03 and S. thermophilus Sfi20 determined by 400-MHz 1H-NMR spectroscopy (A) are identical to the one reported by Doco et al. (11) for S. thermophilus CNCMI 733 (B). Only the 1H-NMR spectrum of the S. thermophilus LY03 exopolysaccharide is shown.
