Title:
LACTASE, BACTERIUM PRODUCING THE SAME AND DAIRY PRODUCT
Document Type and Number:
Japanese Patent JP2005052043
Kind Code:
A
Abstract:
To obtain a lactase that exhibits sufficient lactose degradation activity in a low-temperature environment and is rapidly deactivated by a mild heat treatment.
The lactase has physicochemical properties that has (1) 139±10 kDa molecular weight, exhibits (2) maximum activity at 5-15°C and has (3) activity reduced to ≤10% maximum activity by heat treatment at 45°C for 10 minutes. The bacterium produces the lactase and the dairy product is produced by suitable the enzyme.
