Immobilization of Kluyveromyces lactis β‐Galactosidase on Meso‐macroporous Silica: Use of Infrared Spectroscopy to Rationalize the Catalytic Efficiency

ChemPlusChem, Volume 87, Issue 12, December 2022., 2022
A deeper understanding regarding the enzyme‐carrier interactions and the enzyme conformation may bring clues about the inherent processes that occur during enzyme immobilization. In this study, the enzyme β‐galactosidase was immobilized on a meso‐macroporous silica carrier, and infrared spectroscopy allowed the search for such clues to explain the ...

Comparative Study on Mechanistic Kinetic Modeling of the Enzymatic Synthesis of Galacto‐Oligosaccharides

Chemie Ingenieur Technik, Volume 94, Issue 5, Page 774-779, May 2022., 2022
Mechanistic kinetic modeling via three different kinetic approaches is studied and evaluated for the biocatalyzed synthesis of galacto‐oligosaccharides, with the mechanistic kinetics approach being a promising method. An information criterion (AIC) is used as tool for comparative description and pro and cons of each approach are shown.

Immobilization of β‐Galactosidase on Monolithic Discs for the Production of Prebiotics Galacto‐oligosaccharides

Chemie Ingenieur Technik, Volume 93, Issue 5, Page 838-843, May 2021., 2021
Immobilization of β‐galactosidase offers a sustainable production strategy for the synthesis of prebiotic galacto‐oligosaccharides from lactose. Methacrylate‐based convective interaction monoliths used as pore‐through‐flow enzyme reactors were investigated in different configuration to characterize kinetic parameters and enzyme activity.

Galacto-Oligosaccharides : production, properties, applications, and significance as prebiotics [PDF]

, 2010
Galacto-oligosaccharides (GOS) have now been definitely established as prebiotic ingredients after in vitro and animal and human in vivo studies. Currently, GOS are produced by glycoside hydrolases (GH) using lactose as substrate.
