Figure 3. ¹H-NMR spectra of the exopolysaccharides produced by B. vietnamiensis and B. multivorans.

A) ¹H-NMR spectrum of the EPOLs mixture produced by B. vietnamiensis on YEM agar plates. Anomeric proton signals and methyl groups of 6-deoxy sugars belonging to CEP and BV-EP are shown. B) ¹H-NMR spectrum of the EPOLs mixture produced by B. multivorans C1576 on YEM agar plates: anomeric proton signals and methyl groups of 6-deoxy sugar of CEP are indicated, while triangles indicate new signals.
