CEL3-KG22 CELLULASE GENE FROM RUMINANT STOMACH MICROORGANISM OF BLACK GOAT AND USES THEREOF

摘要

PURPOSE: A Cel3-KG22 product, cellulase, is provided to be used in a feed additive and a detergent composition by finding a cellulase gene from a ruminant stomach microorganism of a black goat, to develop biofuel. CONSTITUTION: A cellulase protein derived from a ruminant stomach microorganism has an amino acid sequence of sequence number 2. A gene encodes the cellulase protein. A recombinant vector contains the gene. The host cell is transformed by the recombinant vector. A method for producing a large amount of cellulase from the host cell comprises a step of transducing the recombinant vector to the host cell and overexpressing cellulase.
