Production of dextran

Dextran-producing strains of Leuconostoc mesenteroides ssp. cremoris, i.e. those registered at the CNCM under the designations l-1692 and l-1693, are new. Also claimed are: (a) production of dextran by fermenting a culture medium containing sucrose by inoculation with a preculture of a selected stra...

Zusammenfassung:	Dextran-producing strains of Leuconostoc mesenteroides ssp. cremoris, i.e. those registered at the CNCM under the designations l-1692 and l-1693, are new. Also claimed are: (a) production of dextran by fermenting a culture medium containing sucrose by inoculation with a preculture of a selected strain of Leuconostoc mesenteroides ssp. cremoris; and (b) recovering an additive containing the enzyme dextran-sucrase from the fermentation product. L'invention concerne une souche bactérienne produisant du dextrane, un procédé de production de dextrane, un procédé de production d'un additif contenant une enzyme impliquée dans la biosynthèse du dextrane ainsi que l'utilisation de ce dextrane, de cette enzyme et/ou d'une souche productrice de ce dextrane et de cette enzyme dans la fabrication d'une composition alimentaire ou cosmétique.
