| Abstract: | Cyclodextrin glucanotransferases (CGTs, EC 2.4.1.19) from mesophilic, thermophilic, and halophilic bacteria and maltase (EC 3.2.1.20) from the yeast Saccharomyces cerevisiae were used for transglycosylation of ascorbic acid with starch, maltodextrin, γ-cyclodextrin, and maltose. These compounds served as donors of glucosyl residues. CGT from thermophilic strains was shown to be the most potent in this respect (the degree of transglycosylation was as high as 60%). |
