ENHANCED-ACTIVITY MODIFIED BETA-GLUCOSIDASE AND A MANUFACTURING METHOD FOR BIOETHANOL USING SAME

摘要

The present invention relates to a beta-glucosidase which has been modified so as to enhance the activity thereof, and to a production method for bioethanol using same. More specifically, the present invention relates to: a polynucleotide coding for a beta-glucosidase which has been modified so as to enhance the activity thereof; beta-glucosidase expressed from the polynucleotide; an expression vector comprising the polynucleotide; a transformant genetically transformed by means of the expression vector; a method for producing the modified beta-glucosidase by using the transformant; and a method for producing bioethanol by using the transformant. The modified beta-glucosidase of the present invention can be used to implement a saccharification process which is even more efficient than with existing beta-glucosidase, and can therefore be widely put to use in the economic production of bioethanol.
