During the growth of Kluyveromyces marxianus var. marxianus ATCC 10022 on lactose, peaks of glucose, but not β-galactosidase activity, were detected in culture medium. Harvested and washed whole cells produced glucose and ...

Here we studied the effect of molecular crowding on the hydrolysis of ortho- and para-nitrophenyl-β-D-galactopyranosides (ONPG, PNPG) catalysed by Escherichia coli β-Galactosidase in the presence of 0–35%w/v 6kD ...

In the present work we studied the catalytic activity of E. coli β-Gal confined in a nanoporous silicate matrix (Eβ-Gal) at different times after the beginning of the sol-gel polymerization process. Enzyme kinetic experiments ...

RESUMEN En el presente trabajo se buscó caracterizar la actividad enzimática de la ß-galactosidasa aislada de un cultivo líquido de Pleurotus ostreatus a base de suero de leche. Para ello, muestras de micelio de P. ostreatus ...

We had demonstrated that membrane adsorption or penetration differentially modulated β-Galactosidase (β-Gal) activity against soluble substrates (Coll. and Surf., 24, 21, 2002). In a heterogeneous media, not only the enzyme ...

Galacto-oligosacáridos (GOS) son prebióticos que se utilizan en las formulaciones de alimentos funcionales. Estos compuestos se producen durante la hidrólisis de lactosa por b-galactosidasa. En este estudio se evaluó la ...

We investigated if in complex environments, like those where β-galactosidase activity is usually assayed, the kinetics of hydrolysis against soluble substrates could be modulated through enzyme-surface interactions. Kinetic ...
