  • The polysaccharide GtfA reuteran is a unique, soluble glucan produced from sucrose by the glucansucrase GtfA-ΔN of Lactobacillus reuteri strain 121. The branched structure contains mainly α(1→4) and α(1→6) glucosidic linkages, with no repeating units present. The production of glucans using lactic acid bacteria is Generally Recognized as Safe (GRAS), and the compounds have potential prebiotic properties.

  • The polysaccharide GtfO-∆N reuteran is a soluble glucan produced from sucrose by the glucansucrase GtfO of Lactobacillus reuteri ATCC 55730 (LB BIO). The branched structure contains mainly 79% α(1→4) and a minor amount 21 % α(1→6) glycosidic linkages, without repeating units present. The production of glucans using lactic acid bateria is Generally Recognized as Safe (GRAS), and the compounds have potential prebiotic properties.

  • The exopolysaccharide Gtf180 dextran is produced using sucrose by the glucansucrase of Lactobaccillus reuteri 180. The heavily branched α-D-glucan has a heterogeneous structure containing α(1→3) and α(1→6) glucosidic linkages with no repeating units present. The terminal positions only carries -α-D-Glcp-(1→6) units, whether all the -α-D-Glcp-α(1→3)- units are 6-substituted. The polysaccharide is formed from different isomalto-oligosaccharides (IMMO), connected by single α(1→3) bridges in linear and branched orientations.

  • The glucansucrase of Lactobacillus reuteri 180 catalysis the synthesis of a diversity of α-glucans from sucrose. An enzyme mutation of Leu940 in domain B significantly changed the linkage and reaction specificity. Compared with GTF180-ΔN, the GTF180-ΔN L940E mutant has an increased percentage α(1→6) linkages, and a decreased percentage of α(1→3) linkages in the product. Furthermore, the mutant enzyme has an increased polysaccharide synthesis.
