title: [Transglycosylation of L-ascorbic acid].
abstract: Cyclodextrin glucanotransferases (CGTase, EC 2.4.1.19) produced by mesophilic, thermophilic, and halophilic bacilli, as well as maltase (EC 3.2.1.20) produced by various strains of Saccharomyces cerevisiae have been applied for transglycosylation of L-ascorbic acid using starch, maltodextrin, gamma-cyclodextrin, and maltose as donors of glucosyl residue. The CGTases produced by thermophilic strains are the most efficient. The degree of transglucosylation is more than 60%.
