Allgemeine Beschreibung

Eine β-Galactosidase Preparation, produziert in einer Flüssigkultur (submerged fermentation) eines selektierten Stamms der Hefe Kluyveromyces lactis.

Anwendung

β-galactosidases from different species, including Kluyveromyces lactis and Kluyveromyces fragilis, hydrolyze lactose.

Biochem./physiol. Wirkung

β-galactosidase cleaves lactose into its monosaccharide components, glucose and galactose. It also catalyzes the transglycosylation of glucose into allolactose, the inducer of β-galactosidase, in a feedback loop.

A fully mechanized Arduino-controlled multi-pumping flow analysis system and procedure for the determination of β-galactosidase activity are proposed. The applied bioanalytical method is based on the determination of p-nitrophenol formed in the course of enzyme-catalyzed hydrolysis of p-nitrophenyl-galactopyranosides. The photometric
