Abstract
The invention discloses a modified cellulase gene and an expression vector and application thereof. A protein has an amino acid composition sequence shown in the formula of SEQ. 1 or is a protein derived from the protein shown in the formula of SEQ. 1 through replacement and/or detection and/or addition of one or more amino acid residues and having cellulase activity. Recombinant plant lactobacillus improves the palatability of the fermented straws, improves the nutritional value of the straws, is free of cellulase in the straw treatment process and greatly reduces a production cost.
