Zusammenfassung:	ABSTRACT Methods of preparing highly purified steviol glycosides, particularly rebaudiosides A, D and M are described. The methods include utilizing recombinant microorganisms for converting various staring compositions to target steviol glycosides. In addition, novel steviol glycosides reb D2 and reb M2 are disclosed, as are methods of preparing the same. The highly purified rebaudiosides are useful as non-caloric sweetener in edible and chewable compositions such as any beverages, confectioneries, bakery products, cookies, and chewing gums. Date Recue/Date Received 2020-08-06 ABRÉGÉ : Il est décrit des procédés de préparation de glucosides de stéviol hautement purifiés, en particulier les rebaudiosides A, D et M. Les procédés incluent lutilisation de micro-organismes recombinés pour convertir diverses compositions fixes pour cibler des glucosides de stéviol. Il est également décrit de nouveaux glucosides de stéviol rebD2 et rebM2, ainsi que leurs procédés de préparation. Les rebaudiosides hautement purifiés sont utiles en tant quédulcorants non caloriques dans des compositions comestibles et des compositions à mâcher comme des boissons, des confiseries, des produits de boulangerie, des biscuits et des gommes à mâcher.
