Comparison of porous starches obtained from different enzyme types and levels [PDF]

, 2016
The objective was to compare the action of different hydrolases for producing porous corn starches. Amyloglucosidase (AMG), α-amylase (AM), cyclodextrin-glycosyltransferase (CGTase) and branching enzyme (BE) were tested using a range of concentrations ...

Research Progress on Enzymatic Preparation and Application of Large-Ring Cyclodextrin [PDF]

Shipin Kexue
Large-ring cyclodextrin (LR-CD) is a cyclic α-1,4-glucan consisting of nine to several hundred glucopyranose units. LR-CD is mainly prepared by the cyclization activity of cyclodextrin glucosyltransferase or 4-α-glucanotransferase that catalyzes ...

Enhanced secretory production of hemolysin-mediated cyclodextrin-glucanotransferase in Escherichia coli by random mutagenesis of the ABC transporter system. [PDF]

, 2010
The hemolysin transport system was found to mediate the release of cyclodextrin glucanotransferase (CGTase) into the extracellular medium when it was fused to the C-terminal 61 amino acids of HlyA (HlyAs(61)).

Synthesis of novel oligomeric anionic alkyl glycosides using laccase/TEMPO oxidation and cyclodextrin glucanotransferase (CGTase)‐catalyzed transglycosylation

Biotechnology and Bioengineering, 2021
Modification of alkyl glycosides, to alter their properties and widen the scope of potential applications, is of considerable interest. Here, we report the synthesis of new anionic alkyl glycosides with long carbohydrate chains, using two different ...

Synthesis of β-Maltooligosaccharides of Glycitein and Daidzein and their Anti-Oxidant and Anti-Allergic Activities

Molecules, 2010
The production of β-maltooligosaccharides of glycitein and daidzein using Lactobacillus delbrueckii and cyclodextrin glucanotransferase (CGTase) as biocatalysts was investigated. The cells of L.

Effect of the Cross Linkers’ Concentration on the Immobilization of Recombinant Escherichia Coli Cells on Hollow Fiber Membrane for Excretion of Cyclodextrin Glucanotransferase (CGTase) [PDF]

, 2017
The excretion of recombinant proteins into the culture medium is a preferred approach over cytoplasmic expression because of the high specific activity and ease of purification.

Cucurbitane Glycosides Derived from Mogroside IIE: Structure-Taste Relationships, Antioxidant Activity, and Acute Toxicity

Molecules, 2014
Mogroside IIE is a bitter triterpenoid saponin which is the main component of unripe Luo Han Guo fruit and a precursor of the commercially available sweetener mogroside V. In this study, we developed an enzymatic glycosyl transfer method, by which bitter

A review on immobilization strategy of cyclodextrin glucanotransferase producing Escherichia coli as whole cell biocatalyst

, 2021
This paper reviewed the immobilization strategy on cyclodextrin glucanotransferase (CGTase) producing Escherichia coli as whole cell biocatalyst. Biotransformation of insoluble substrate such as starch and lignocellulosic biomass with whole cell leads to
