CGTase have focused on trying to understand the mechanism of the cyclization reaction and to find or engineer a CGTase that produces a specific type of CD. CGTases from B. macerans was purchased from Amano Pharma-ceutical Co., Ltd. (Aichi, Japan) and was used without further purifi-cation.

Cyclodextrin glycosyltransferases (CGTases) (EC 2.4.1.19) catalyze the conversion of starch or starch derivates into mixtures of α-, β-, and γ-cyclodextrins. Because time-consuming and expensive purification procedures hinder the widespread application of single-ingredient cyclodextrins, enzymes with enhanced specificity are needed. In this study, we tested the hypothesis that the α

Em continuação, buscou-se à otimização das condições de produção das CDs pela CGTase Amano, pela metodologia do planejamento experimental. A novel enzymatic process for cyclodextrin (CD) production was developed by utilizing sucrose as raw material instead of corn starch. Cyclodextrin glucanotransferase (CGTase) from Bacillus macerans was applied to produce the CDs from linear α-(1,4)-glucans, which were obtained by Neisseria polysaccharea amylosucrase (NpAS) treatment on sucrose. The greatest CD yield (21.1%, w/w) was achieved One unit of CGTase was defined as the amount of enzyme that produced 1 µmol of β-cyclodextrin per minute. Culture media and cultivation Basal medium consisting of 30.0 g maltose, 2.0 g (NH 4 ) 2 SO 4 , 1.0 g KH 2 PO 4 , 1.0 g K 2 HPO 4 , 0.2 g MgSO 4 · 7H 2 O, 2.0 g yeast extract, and 2.0 g polypeptone in 1000 mL distilled water (pH 7.0), was used for a jar fermenter culture, unless A CGTase with high coupling activity using γ-cyclodextrin isolated from a novel strain clustering under the genus Carboxydocella Glycobiology , Mar 2015 Kazi Z G Ara , Pontus Lundemo , Olafur H Fridjonsson , Gudmundur O Hreggvidsson , Patrick Adlercreutz , Eva Nordberg Karlsson 2016-03-09 · Immobilisation of cyclodextrin glucanotransferase (CGTase) on nanofibres was demonstrated.

All other chemicals used were of reagent grade. 2.2. the Preparation and characterization of CGTase In our work, the CGTase from Thermoanaerobacter sp. (Toruzyme 3.0 L) gave a higher yield than that from Bacillus macerans (CGTase Amano). In contrast with the CGTase from Bacillus macerans (the HPLC chromatogram showed four different compounds with increasing concentration, indicating the formation of the so‐called analogous series, Figure 2 The distance of CGTase (EC 2.4.1.19) from Bacillus macerans was purchased from the needle tip from the substrate was varied in the range of 10 Amano Enzyme, Inc. (Japan), and was used without further puriﬁ- to 25 cm. The electrospraying modes were observed using a digi- cation. The crude CGTase extract with the corn starch substrate showed a productivity of 0.38 mmol/L/h, which was 29 % lower than using the purified enzyme and the corn starch substrate but 7 % higher (Toruzyme 3.0 L) gave a higher yield than that from Bacillus macerans (CGTase Amano).

The nanofibres that consist of immobilised CGTase were crosslinked with glutaraldehyde vapour. The synthesis of curcumin oligosaccharides was performed by incubating the reaction mixture (10 mL) containing 0.2 mmol of curcumin d-glucoside, 5 g of soluble starch, and 200 units of CGTase from Bacillus macerans purchased from Amano Pharmaceutical Co. Ltd. in 25 mM sodium phosphate buffer (pH 7.0) at 40 °C for 24 hours. CGTase derived from Bacillus macerans was obtained as a kind gift from Amano Enzyme, Inc., Nagoya, Japan, in a stock solution that was used as supplied and stored at 5 °C.

CGTase was purchased from Amano Enzyme Europe Ltd (Milton Keynes, UK) and Toruzyme 3.0L was obtained from Novozyme A/S (Bagsvaerd, Denmark). Dodecyl-β-maltooctaoside was produced in-house as described previously (Svensson et al. 2009a). Cyclodextrin glucanotransferase from Bacillus macerans (CGTase Amano) was purchased from Amano Pharmaceutical Co., Ltd. (Nagoya, Japan).
