title: [Immobolization of beta-galactosidase on silochrome].
abstract: Beta-Galactosidase (beta-D-galactoside galactohydrolase 3.2.1.23) from Curvularia inaequalis was immobilized by glutaric dialdehyde on gamma-aminopropyl triethoxysilane treated porous siliceous carrier silochrome. From the crude preparation with a specific activity of 3.1 U/mg immobilized beta-galactosidase with an activity of 113 U/g was obtained. The immobilized enzyme did not show significant changes in its enzymic properties. The column filled with the resultant preparation and used to hydrolyze lactose in milk whey maintained 50% of its initial activity after a 30-day work at 50 degrees C.
