Dextran from Leuconostoc mesenteroides

CAS No.: 9004-54-0

Dextran is a mixture of polysaccharides, a complex branched glucan. It is a glucose polymer where the linkage between glucose units are almost entirely of the α-1,6-glucan type. Dextran is a white or almost white lyophilized powder. It is soluble in water, slightly soluble in ethanol. Dextran is manufactured by hydrolysis and fractionation of polysaccharides produced by fermentation of sucrose using certain strains of Leuconostoc mesenteroides
