Differentiation of dextran-producing leuconostoc strains by a modified randomly amplified polymorphic DNA protocol
Seven dextran-producing Leuconostoc strains were differentiated by using a modified randomly amplified polymorphic DNA (RAPD) protocol that incorporated specific primers designed from conserved regions of dextransucrase genes. RAPD profiles showed intraspecies differences among the Leuconostoc mesenteroides strains tested. This modified RAPD protocol will aid in the differentiation of polymer-p...
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...
متن کاملCharacterization of Leuconostoc strains isolated from fresh anchovy (Engraulis anchoita).
The biomass value of anchovy (Engraulis anchoita), the most abundant fi sh species in the Southwest Atlantic Ocean, is considered to be around 4,300,000 tons, with a maximum sustainable yield of 1,140,000 tons (Cabrer et al., 2002), being at present under exploited at 27,800 tons/year (SAGPyA, 2008). Recently, as part of the FAO’s project Towards a Sustainable Aquaculture: Selected Issues and G...
متن کاملProduction of Dextran by Newly Isolated Strains of Leuconostoc mesenteroides PCSIR-4 and PCSIR-9
Different isolated strains of Leuconostoc mesenteroides produce dextran compared with that of L. mesenteroides NRRL B-512 F. Among nine newly isolated strains, strains PCSIR-4 and PCSIR-9 produced dextran of different quality. Using these two newly isolated strains, the development of dextran coincided closely with the disappearance of sucrose. The yield of dextran increased during growth and m...
