OVER-EXPRESSION SYSTEM OF GLUCOSIDASE FROM BIFIDOBACTERIUM ANIMALIS SUBSP. LACTIS SH5 AND BIFIDOBACTERIUM BIFIDUM BGN4 TRANSFORMED WITH THE OVER-EXPRESSION SYSTEM

摘要

The present invention relates to an over-expression system of glucosidase from bifidobacterium animalis subsp. lactis SH5 and bifidobacterium bifidum BGN4 transformed thereby, and when transforming bifidobacterium bifidum BGN4 by using an expression system of beta-glucosidas of the present invention, beta-glucosidase having significantly high activity can be produced. The beta-glucosidase manufactured like this can be used for hydrolyzing glycosides in a form of non-glycosides present in plants.
