Dextran from Leuconostoc mesenteroides

Descrição detalhada : Dextran is a D-glucosyl homopolysaccharide which has a-1,6 glucosidic linkages with different branches through alpha-1,2, alpha-1,3, and alpha-1,4 linkages correspondingly classified as group A, B and C. It can be synthesized from sucrose by cell-free filtrate., Dextrans are polysaccharides with molecular weights >=1,000 Dalton, with a linear backbone of alpha-linked D-glucopyranosyl repeating units. Dextrans are found as bacterial extracellular polysaccharides. They are synthesized from sucrose by Leuconostoc mesenteroides and Lactobacillus brevis. Bacteria employ dextran in biofilm formation or as a protective coating to evade host phagocytes in the case of pathogenic bacteria.Dextran from Leuconostoc mesenteroides (Mw: 25,000) may be used as an analytical standard to calibrate the column for gel permeation chromatography (GPC).
