| abstract |
The invention provides novel cellulase, a gene for encoding the cellulase, a recombinant carrier comprising the encoding gene, a genetic engineering bacterium, and an application of the cellulase in the preparation of an asparagus dietary fiber. The amino acid sequence of the cellulase is shown in SEQ ID NO.1, the sequence of the encoding gene is shown in SEQ ID NO:2, the optimal reaction temperature is 30-40 DEG C, and the optimal pH(Potential of Hydrogen) range is 6.0-7.0. The cellulase provided by the invention can be well applied to the production of the asparagus dietary fiber. |
