Fig. 4.From: Lyophilized alginate-based microspheres containing Lactobacillus fermentum D12, an exopolysaccharides producer, contribute to the strain’s functionality in vitro1H NMR spectra of EPS-r1 (a) and EPS-r2 (b) in D2O recorded at 500 MHz and 50 °C. a α-1,4 Glcp and α-1,6 Glcp = anomeric protons of 1,4- and 1,6-linked glucopyranose; b in the EPS-r2 spectrum the stars indicate the two most intense anomeric proton resonances attributed to t-Glcp and 2,6-GalfBack to article page
