| Comparison of Physico-chemical Properties of Dextran produced by Leuconostoc mesenteroides CMG713 and reference strain of Leuconostoc mesenteroides NRRL B512F. |
Comparison of physical and chemical properties of dextran produced by Leuconostoc mesenteroides CMG713 with that of L. mesenteroides NRRL B512F is presented in Table. Dextran produced by L. mesenteroides CMG713 was amorphous and colourless.
However, different dextrans produced by variants of L. mesenteroides produced range from gelatinous mass to granular precipitates. These physical variations may be due to differences in molecular aggregation.
Dextran produced by L. mesenteroides CMG713 was soluble in water giving a homogenous mixture of 5% solution, which was used for the analysis of the physical and chemical properties. Similar results have been reported for dextran produced by L. mesenteroides NRRL B512F that was also freely soluble in water, methyl sulfoxide, formamide, ethylene glycol and glycerol.
