Abstract
A preparation method conducive to enhancing enzymatic activity of cellulase includes the steps of preparing a first inducer, preparing preculture hyphae, producing enzymes by a single strain, feeding a second inducer, and producing enzymes by co-culture strains. Main ingredients of the first inducer and the second inducer are cellulose and lactose, respectively. The enzymatic activity of the cellulase produced is enhanced by induction of cellulose and lactose and co-culture of Trichoderma and Aspergillus.
