Lactose removing from some dairy products by β-galactosidase produced from genetically modified bacteria

Abstract

Lactose intolerance (LI) is a disturbing problem for patient who can’t digest lactose owing to deficiency in their intestinal β-galactosidase enzyme. β-galactosidase enzyme is a one of hydrolysis enzymes that splits lactose into glucose and galactose and each of them are easily digested in intestine. Two possible processes can be used for solving LI problem, the augment of lactase or the addition of probiotics that have the ability to metabolize lactose.
