Production of Cyclomaltononaose (δ-Cyclodextrin) by Various Cyclodextrin Glycosyltransferases

Applied Microbiology and Biotechnology, 1999
The conversion of soluble starch to cyclomaltohexaose (α-CD), cyclomaltoheptaose (s-CD), cyclomaltooctaose (γ-CD) and cyclomaltononaose (δ-CD) by crude preparations of cyclodextrin glycosyltransferase (EC 2.4.1.19) (CGTases) from Bacillus spp. and bacterial isolates was studied.

Cyclodextrin production by cyclodextrin glycosyltransferase from Bacillus circulans DF 9R

Bioresource Technology, 2007
Cyclodextrins (CD) are cyclic oligosaccharides with multiple applications in the food, pharmaceutical, cosmetic, agricultural and chemical industries. In this work, the conditions used to produce CD with cyclodextrin glycosyltransferase from Bacillus circulans DF 9R were optimized using experimental designs.

Gamma-Cyclodextrin Production Using Cyclodextrin Glycosyltransferase from Bacillus clarkii 7364

Applied Biochemistry and Biotechnology, 2012
The production of cyclodextrins (CDs) by cyclodextrin glycosyltransferase (CGTase) from Bacillus clarkii 7364 was studied. Forty-seven percent (w/w) conversion rate to γ-CD was obtained in the process performed by reacting 5 U per gram of starch CGTase with 15 % (w/v) soluble starch in 0.025 M sodium phosphate-NaOH buffer (pH 12) at 55 °C in the ...

Alpha-Cyclodextrin Production using Cyclodextrin Glycosyltransferase fromKlebsiella pneumoniae AS-22

Starch - Stärke, 2001
Alpha-cyclodextrin (α-CD) production, using cyclodextrin glycosyltransferase (CGTase) from Klebsiella pneumoniae AS-22, was investigated in the presence of various complexing agents using raw wheat starch and dextrin as substrates. The addition of many alcohols resulted in increased conversion of both raw wheat starch and dextrin to α-CD.

Mutations enhance β-cyclodextrin specificity of cyclodextrin glycosyltransferase from Bacillus circulans

Carbohydrate Polymers, 2014
The effects of amino acid residue at position 31 in the neighborhood of calcium binding site I (CaI) on product specificity of cyclodextrin glycosyltransferase (EC 2.4.1.19, CGTase) were investigated by replacing Ala31 in the CGTase from Bacillus circulans STB01 with arginine, proline, threonine, serine and glycine.
