Absorción mineral y retención ósea en ratas normales en crecimiento por el consumo de un yogur experimental reducido en lactosa que contiene galactooligosacáridos (GOS)

Actual. osteol; 18 (2), 2022
Introducción: Los GOS son prebióticos naturales presentes en la leche materna que pue-den obtenerse enzimáticamente a partir de la lactosa de leche de vaca durante la fabricación de yogur. El producto lácteo resultante será reducido en lactosa y contendrá prebióticos y bacterias pot...

Synthesis of b(1 ? 3) and b(1 ? 6) galactooligosaccharides from lactose and whey using a recombinant b-galactosidase from Pantoea anthophila

Electron J Biotechnol; 49 (), 2021
BACKGROUND: Milk whey, a byproduct of the dairy industry has a negative environmental impact, can be used as a raw material for added-value compounds such as galactooligosaccharides (GOS) synthesis by bgalactosidases. RESULTS: B-gal42 from Pantoea anthophila strain isolated from tejuino belonging to the ...

Overviewing the Application of β-Galactosidase “Immobilized on Nanoparticles” in Dairy Industries

Abstract Owing to the excellent catalytic potential, β-galactosidase (EC: 3.2.1.23) has been exploited as an important industrial enzyme for obtaining galactooligosaccharides (GOS) and lactose-free products in dairy industries. Moreover, novel technologies have been implemented in the recent past fo...

Reducción de proteínas y glucosa por reacción de Maillard en leche con lactosa hidrolisada

Rev. chil. nutr; 47 (1), 2020
Se evaluó el efecto de la temperatura sobre la desnaturalización de proteínas y la reacción de Maillard en leche entera y descremada con lactosa hidrolizada. Las leches hidrolizadas se trataron térmicamente a 100, 110, 120 y 130 °C durante un período de 1 hora y se midió la concentración de gluc...

Modeling of lactose enzymatic hydrolysis using Monte Carlo method

Background: Mathematical modeling is useful in the analysis, prediction, and optimization of an enzymatic process. Unlike the conventional modeling methods, Monte Carlo method has special advantages in providing representations of the molecule’s spatial distribution. However, thus far, Monte Carlo mode...

Biochemical characterization of three Aspergillus niger β-galactosidases

Background: β-Galactosidases catalyze both hydrolytic and transgalactosylation reactions and therefore have many applications in food, medical, and biotechnological fields. Aspergillus niger has been a main source of β-galactosidase, but the properties of this enzyme are incompletely studied. Results: ...

Permeabilization of Saccharomyces fragilis IZ 275 cells with ethanol to obtain a biocatalyst with lactose hydrolysis capacity

Acta sci., Biol. sci; 38 (2), 2016
The permeabilization was used to transform microorganisms in cell biocatalysts with high enzymatic activity. The Saccharomyces fragilis IZ 275 yeast cells were permeabilized with ethanol, as permeabilizing agent. To optimize the permeabilization conditions were used the design of Box-Behnken 15 trials (3...

Conserved genes and pathways in primary human fibroblast strains undergoing replicative and radiation induced senescence

Biol. Res; 49 (), 2016
BACKGROUND: Cellular senescence is induced either internally, for example by replication exhaustion and cell division, or externally, for example by irradiation. In both cases, cellular damages accumulate which, if not successfully repaired, can result in senescence induction. Recently, we determined the...

Protocolo de evaluación rápida de seguridad y efectividad del uso de Agalsidasa beta en el tratamiento de pacientes con enfermedad de Fabry
Protocol of rapid evaluation of security and effectiveness of the use of Agalsidasa beta in the treatment of patients with Fabry disease

La enfermedad de Fabry es una enfermedad progresiva heterogénea multisistémica hereditaria que afecta tanto a hombres como a mujeres. Se caracteriza por la deficiencia de α-galactosidasa. La actividad reducida o inexistente de la α-glucosidasa provoca la acumulación de GL-3 en los lisosomas de mucho...
