Production of Hesperetin Glycosides by Xanthomonas campestris and Cyclodextrin Glucanotransferase and Their Anti-allergic Activities
نویسندگان
چکیده
The production of hesperetin glycosides was investigated using glycosylation with Xanthomonas campestris and cyclodextrin glucanotransferase (CGTase). X. campestris glucosylated hesperetin to its 3'-, 5-, and 7-O-glucosides, and CGTase converted hesperetin glucosides into the corresponding maltosides. The resulting 7-O-glucoside and 7-O-maltoside of hesperetin showed inhibitory effects on IgE antibody production and on O2- generation from rat neutrophils.

The production of beta-maltooligosaccharides of glycitein and daidzein using Lactobacillus delbrueckii and cyclodextrin glucanotransferase (CGTase) as biocatalysts was investigated. The cells of L. delbrueckii glucosylated glycitein and daidzein to give their corresponding 4'- and 7-O-beta-glucosides. The beta-glucosides of glycitein and daidzein were converted into the corresponding beta-malto...

The production of β-maltooligosaccharides of capsaicin was investigated using Lactobacillus delbrueckii and cyclodextrin glucanotransferase (CGTase) as biocatalysts. The cells of L. delbrueckii glucosylated capsaicin to give its β-glucoside. The β-glucoside of capsaicin was converted into the corresponding β-maltoside and β-maltotrioside by CGTase. On the other hand, β-melibioside and β-isomalt...
متن کاملUse of Date Syrup as Agricultural Waste for Xanthan Production by Xanthomonas campestris
Xanthomonas campestris was used for producing xanthan gum using date syrup, prepared from low quality dates, as a substrate. Fermentation was carried out with date syrup and sucrose syrup at 28 ˚C and pH 6.8 in a rotary benmarin shaker (240 rpm). The effect of fermentation period (24, 48, 72, 96 and 120 h) on xanthan gum production was studied. The results showed that EPS concentration increase...

The glycosylation of αand δ-tocopherols using Klebsiella pneumoniae and cyclodextrin glucanotransferase (CGTase) was investigated. K. pneumoniae converted αand δ-tocopherols into the corresponding β-glucosides in 10 and 8% yield, respectively. CGTase glycosylated α-tocopheryl β-glucoside to α-tocopheryl β-maltoside (51%) and αtocopheryl β-maltotrioside (35%). On the other hand, δ-tocopheryl β-g...
