Cyclodextrin glucanotransferase immobilization onto functionalized magnetic double mesoporous core-shell silica nanospheres

Electron. j. biotechnol; 17 (2), 2014
Background Cyclodextrin glucanotransferase (CGTase) from Amphibacillus sp. NPST-10 was covalently immobilized onto amino-functionalized magnetic double mesoporous core-shell silica nanospheres (mag@d-SiO2@m-SiO2-NH2), and the properties of the immobilized enzyme were investigated. The synthesis process o...

A new low molecular mass alkaline cyclodextrin glucanotransferase from Amphibacillus sp. NRC-WN isolated from an Egyptian soda lake

Electron. j. biotechnol; 16 (6), 2013
Background: Cyclodextrin glucanotransferase (CGTase) is one of the most industrially important enzymes used in the commercial production of cyclodextrins (CDs). Alkaliphilic bacteria have attracted much interest in the last few decades because of their ability to produce extracellular enzymes that are ac...

Immobilization of cyclodextrin glucanotransferase on aminopropyl-functionalized silica-coated superparamagnetic nanoparticles

Electron. j. biotechnol; 16 (6), 2013
Background: Cyclodextrin glycosyltransferase (CGTase) from Amphibacillus sp. NPST-10 was successfully covalently immobilized on aminopropyl-functionalized silica coated superparamagnetic nanoparticles; and the properties of immobilized enzyme were investigated. The synthesis process included preparing of...

Application of response surface methodology for glucosyltransferase production and conversion of sucrose into isomaltulose using free Erwinia sp. cells

Isomaltulose is a structural isomer of sucrose commercially used in food industries. Glucosyltransferase produced by Erwinia sp. D12 catalyses an intramolecular transglucosylation of sucrose giving isomaltulose. The Experimental design and response surface methodology were applied for the optimization of...

Estudio del sestema fosforilasa en la cirrosis hepática del niño
[Study of the phosphorylase system in hepatic cirrhosis in children]

Arch. argent. pediatr; 69 (5), 1971
Tuvimos oportunidad de medir la hiperglucemia glucogenolítica por inducción hormonal exógena con glucagón endovenoso, en 7 niños cirróticos (4 cirrosis biliares secundarias por atresia de vías biliares y 3 cirrosis postnecrótica posthepatítica), hallando que todos brindan menor respuesta hipergl...
