Preparation and characterization of dextran from Leuconostoc mesenteroides.

In conjunction with investigations on the a-l, 6-glucosidic linkage in starch, it was desirable to conduct comparative studies on other substances containing this linkage. The dextran from Leuconostoc mesenteroides, a polysaccharide having predominantly a-1 ,6-glucosidic linkages, was selected to be used directly in these comparative studies and to provide a source of simpler substances contain...

Characteristics of Leuconostoc mesenteroides from Cane Juice.

Purification and Characterization of Dextransucrase from Leuconostoc Mesenteroides Nrrl B-1149

Leuconostoc mesenteroides NRRL B-1149 produces extracellular dextransucrase which in this study was purified using different concentrations of polyethylene glycol (PEG). The dextran produced by this enzyme is unique in that it contains α(16) and α-(13) linkages which have clinical applications. The cell free supernatant with 0.9 U/mg enzyme specific activity was subjected to fractionation by ...

Characterization of the Dextran Produced by Leuconostoc mesenteroides from Date Fruit Extract

In the present study, the production of dextran from date extract and sucrose as carbon sources by the bacterium Leuconostoc mesenteroides NRRL B512 (f) was investigated. In comparison to blue dextran (Mw≈2000 Da), dextran molecular weight was reduced (Mw2000 KDa). Flow behavior indices of dextran solutions from date extracts were investigated and rheological parameters were evaluated at concen...
