The present invention has a purpose of providing a β-galactosidase enzyme useful for the production of oligosaccharides. Disclosed is a β-galactosidase enzyme comprising the amino acid sequence of any one of SEQ ID NOs: 1 to 4 or an amino acid sequence that is 80% or more identical to said amino acid sequence.

Beta-galactosidase enzymes

The present invention has a purpose of providing a novel β-galactosidase enzyme useful for the production of oligosaccharides. Disclosed is a β-galactosidase enzyme comprising the amino acid sequence of any one of SEQ ID NOs: 1 to 4 or an amino acid sequence that is 80% or more identical to said amino acid sequence.

A lactase bulk powder and a lactase preparation both have improved storage stability. The stability of a lactase bulk powder is improved by regulating the acceptable amount of glucose and/or galactose, generated during manufacturing the lactase bulk powder, within a preset range. The lactase bulk powder includes lactase, galactose and/or glucose. The total amount of galactose and glucose is more than 0 &#x3bc;mol and not more than 50 &#x3bc;mol per 100,000 U of lactase. The lactase preparation has the lactase bulk powder as an active ingredient.

Lactase bulk powder and lactase preparation

The present invention has a purpose of providing a novel &#x3b2;-galactosidase enzyme useful for the production of oligosaccharides. Disclosed is a &#x3b2;-galactosidase enzyme comprising the amino acid sequence of any one of SEQ ID NOs: 1 to 4 or an amino acid sequence that is 80% or more identical to said amino acid sequence.
