NOVEL THERMOSTABLE BETA-GLUCOSIDASE AND THE METHODS OF PREPARATION THEREOF

摘要

The present invention relates to novel beta-glucosidase and a method for preparing the same. The present invention relates to beta-glucosidase isolated from T. pacificus, a gene encoding the beta-glucosidase, a recombinant vector including the gene, a host cell transformed by the recombinant vector, and a method for preparing beta-glucosidase by using the host cell. The beta-glucosidase according to the present invention shows hydrolysis activity on various pNP-glucopyranoside and oligosaccharide as well as laminarin. In particular, the beta-glucosidase shows exo-hydrolysis activity on laminarin, thereby being used to degrade laminarin in combination with endo-hydrolase.
