Kochikyan V.T., Markosyan A.A., Abelyan L.A., Balayan A.M., and Abelyan V.A. Combined Enzymatic Modification of Stevioside and Rebaudioside A

—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.

Cyclodextrin glucanotransferases (CGTases, EC 2.4.1.19) produced by mesophilic, thermophilic, alkaliphilic, and halophilic bacilli were used for transglycosylating stevioside (in order to remove bitterness and aftertaste), with cyclodextrins (CDs) being used as donors. It was shown that CGTases produced by extremophilic microorganisms are effective biocatalysts. Optimum temperature and pH of these enzymes were 45°C and pH 6.5–7.5, respectively. T...

Статья попубликована в Annals of Microbiology, 59 (4) 745-747 (2009). Bacillus subtilis isolates B2, B6 and Bacillus brevis isolate EN63-1 were evaluated for control of apple gray mould caused by Botrytis mali isolate 20JR. These isolates were evaluated alone, or in combination with sodium bicarbonate on artificially inoculated Golden Delicious apple cultivar. Treated fruit were stored at 4 and 20 °C for 30 and 14 days respectively. When applied...

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, 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 a...
