Dextran is now produced from sucrose by certain lactic acid bacteria of the family lactobacillus. Species include Leuconostoc mesenteroides and Streptococcus mutans. The structure of dextran produced depends not only on the family and species of the bacterium but on the strain.

Dextran Structure. Dextran is an α-D-1,6-glucose-linked glucan with side-chains 1-3 linked to the backbone units of the Dextran biopolymer. The degree of branching is approximately 5% in native (unfractionated) dextran and decreases with decreasing molecular weight. The branches are mostly 1-2 glucose units long.
Dextran is a biodegradable neutral bacterial exopolysaccharide consisting of repeating glucose subunits. Dextran is soluble in water and organic solvents, and this feature can be used in the preparation of different structures through blending dextran with bioactive agents or hydrophobic polymers.
Jul 1, 2021 · The characteristics of dextran depend on the LAB or enzyme of origin, which makes each dextran unique in terms of molecular structure, molecular weight, and branching, which cause variations in the viscosity and flexibility, and thermal and rheological properties.
Feb 16, 2010 · Dextran is a complex, branched polysaccharide made of many glucose molecules joined into chains of varying lengths. The straight chain consists of α (1→6) glycosidic linkages between glucose molecules, while branches begin from α (1→3) linkages (and in some cases, α1→2 and α1→4 linkages as well).
