Reaction mechanism of isomaltooligosaccharides synthesis by ?-glucosidase fromAspergillus carbonarious

Synthesis of long-chain isomaltooligosaccharides from tapioca starch and an in vitro investigation of their prebiotic properties

“…Accordingly, several research groups have investigated a new process to produce IMOs in a more efficient way. Usually, the production of IMOs from starch has required a multi-stage process [7][8][9][10]. Starch is first hydrolysed into ␣-1,4-linked dextrins, with ␣-amylase (E.C.…”

Production of isomaltooligosaccharides from banana flour

“…A high concentration of water in the system might be undesirable, since water acts as a competitive acceptor and leads to maltose hydrolysis . Some micro‐organisms produce α‐glucosidases with strong transglucosylation activity, such as Aspergillus niger , Aureobasidium pullulans , Aspergillus carbonarius , Aspergillus nidulans , Bacillus stearothermophilus and Xanthophyllomyces dendrorhous . IMOs can also be produced by treatments of sucrose with dextransucrase and dextranase and of dextran with dextranase .…”

Production of high‐purity isomalto‐oligosaccharides syrup by the enzymatic conversion of transglucosidase and fermentation of yeast cells

“…However, the transglucosidase from Aspergillus niger acts only on low degree-of-polymerization (DP) oligomers of glucose. Enzymes with transglucosylation activity have also been found in many other fungi such as Aureobasidium pullulans (Yun et al, 1994), Aspergillus carbonarious (Duan et al, 1994), and Aspergillus nidulans (Kato et al, 2002). Kuriki et al (1993) reported that an enzyme called neopullulanase in Bacillus subitlis has the function of a-(1,6)transglucosylation.…”
