Characterization of the Different Dextransucrase Activities Excreted in Glucose, Fructose, or Sucrose Medium by Leuconostoc mesenteroides NRRL B-1299.
When grown in glucose or fructose medium in the absence of sucrose, Leuconostoc mesenteroides NRRL B-1299 produces two distinct extracellular dextransucrases named glucose glucosyltransferase (GGT) and fructose glucosyltransferase (FGT). The production level of GGT and FGT is 10 to 20 times lower than that of the extracellular dextransucrase sucrose glucosyltransferase (SGT) produced on sucrose...
متن کاملGrowth and energetics of Leuconostoc mesenteroides NRRL B-1299 during metabolism of various sugars and their consequences for dextransucrase production.
The metabolic and energetic properties of Leuconostoc mesenteroides have been examined with the goal of better understanding the parameters which affect dextransucrase activity and hence allowing the development of strategies for improved dextransucrase production. Glucose and fructose support equivalent specific growth rates (0.6 h-1) under aerobic conditions, but glucose leads to a better bio...

متن کاملPreparation 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...
متن کاملCharacterization 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...
