Maltooligosaccharides production catalysed by cyclodextrin glycosyltransferase from Bacillus circulans DF 9R in batch and continuous operation

Autor: Hernán Costa, Susana Alicia Ferrarotti, Jorgelina Andrea Rodríguez Gastón, Norberto Krymkiewicz, Ana Lía Rossi

Publikováno v: Process Biochemistry. 47:2562-2565

Cyclodextrin glycosyltransferase catalyses the synthesis of cyclodextrins from starch by intramolecular transglycosylation. However, under certain conditions, the reaction can be directed towards the production of linear dextrins, suppressing the syn

Cyclodextrin glycosyltransferase from Bacillus circulans DF 9R: Activity and kinetic studies

Autor: Jorgelina Andrea Rodríguez Gastón, Norberto Krymkiewicz, Natalia Szerman, Susana Alicia Ferrarotti, Hernán Costa

Publikováno v: Enzyme and Microbial Technology. 45:36-41

Activity characteristics and kinetic aspects of a cyclodextrin glycosyltransferase (CGTase) from Bacillus circulans DF 9R were studied. A mixture of α-, β- and γ-cyclodextrins (CDs), glucose, maltose and negligible amounts of longer linear dextrin

Publikováno v: Journal of Biotechnology. 125:85-94

Immobilization of alcohol dehydrogenase (ADH) from Horse Liver inside porous supports promotes a dramatic stabilization of the enzyme against inactivation by air bubbles in stirred tank reactors. Moreover, immobilization of ADH on glyoxyl-agarose pro

Stabilization of a Formate Dehydrogenase by Covalent Immobilization on Highly Activated Glyoxyl-Agarose Supports

Autor: Lorena Wilson, Susana Alicia Ferrarotti, Jose M. Guisan, Cesar Mateo, Juan M. Bolivar, Roberto Fernandez-Lafuente

Publikováno v: Biomacromolecules. 7:669-673

Formate dehydrogenase (FDH) is a stable enzyme that may be readily inactivated by the interaction with hydrophobic interfaces (e.g., due to strong stirring). This may be avoided by immobilizing the enzyme on a porous support by any technique. Thus, e
