Abstract:
The subject matter of the invention is dextrans which have between 95% and 99% of α-1,6 glucosidic bonds, a weight-average molar mass Mw at least equal to 0.7×109 g.mol−1, and a dispersity index D of between 1.3 and 3. The invention also relates to a dextran saccharase which makes it possible to produce such dextrans, and to a method for producing said dextrans.
