Characterization of beta-galactosidase immobilized into poly(hydroxyethylmethacrylate) membranes

, 1998
beta-galactosidase was immobilized into pHEMA membranes with the highest specific activity yield of 9.5%. The specific activity of the entrapped enzyme was found to be decreased as the enzyme loading increased in pHEMA membranes.

Development of a gene-editing strategy to overcome genetic intractability in Lactobacillus johnsonii

Journal of Bacteriology
Genetic editing in lactobacilli is often constrained by their robust defense mechanisms against foreign DNA and low transformation efficiency, resulting in pronounced species- and strain-specific variability in the performance of genetic tools.

Identification of bacteria with beta-galactosidase activity in faeces from lactase non-persistent subjects

, 2005
Previous studies suggest that, besides the maldigestion of lactose in the small intestine, the colonic processing of lactose might play a role in lactose intolerance.

When should we think about Fabry disease?

Journal of Education, Health and Sport
According to the European Union definition, a rare disease is a disease that occurs with a frequency of less than 5 per 10,000. Rare diseases pose a major diagnostic problem for physicians.

Beta-Galactosidase Production from Streptococcus thermophilus Isolated from Milk Yoghurt [PDF]

, 2008
Beta-Galactosidase was an intracellular enzyme isolated from Streptococcus thermophilus grown in whey. The Beta-Galactosidase from Streptococcus thermophilus exhibited twice the activity of enzyme from Saccharomyces fragilis being stable at 4 °C and ...

Improved in situ beta-galactosidase staining for histological analysis of transgenic mice

, 1994
The present study describes a novel method for the histochemical demonstration of beta-galactosidase activity on tissue sections. We have replaced 5-bromo-4-chloro-3-indolyl-beta-D-galactoside (X-Gal) with 5-bromo-indolyl-beta-o-galactopyranoside (Bluo ...
