Ebook: Combined Enzymatic Modification of Stevioside and Rebaudioside A

Article. - Publicied in: Appl. Biochem. Microbiol., 2006, vol.42, pp.31–37.
Cyclodextrin glucanotransferases (CGTases, EC 2.4.1.19) produced by mesophilic, thermophilic,
alkaliphilic, and halophilic bacilli were used for transglycosylating stevioside and rebaudiosides A with the use of starch as a donor. CGTases produced by Bacillus stearothermophilus B-5076 B. macerans
BIO-4m were the most effective biocatalysts. This method can be used successfully for direct transglycosylation of stevia extract without purification of its individual components.
