General description

A β-galactosidase preparation produced by submerged fermentation of a selected strain of the yeast Kluyveromyces lactis.

Application

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

Biochem/physiol Actions

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.
