THERMOSTABLE SUCROSE PHOSPHORYLASE

摘要

The present invention relates to a sucrose phosphorylase from Bifidobacterium adolescentis which is useful as a biocatalyst in carbohydrate conversions at high temperatures. Indeed, the biocatalysts of the present invention are enzymatically active for a time period of at least 16 h and up to 1 to 2 week(s) at a temperature of at least 60° C. The biocatalysts of the present invention are: a) immobilized on an enzyme carrier, or b) are part of a cross-linked enzyme aggregate (CLEA), and/or c) are mutated, and/or d) are enzymatically active in the continuous presence of their substrate.
