The invention discloses a fermentation bacteria agent and a preparation method and an application thereof. The preparation method comprises the following steps: (1) mixing unsterilized cabbage stems, orange peels and wheat bran according to the weight ratio of (0.8-1.2):(1.5-1.9):(0.3-0.5), and adding water to wet the mixture, thereby obtaining a culturing substrate; (2) inoculating Aspergillus niger, Trichoderma koningii and wheat koji into the culturing substrate to be stirred evenly; and (3) carrying out a stationary culturing, thereby obtaining the fermentation bacteria agent. The invention further provides the fermentation bacteria agent obtained by utilizing the preparation method and the application thereof in the production of a cellulose compound enzyme system. Compared with the prior art, the preparation method provided by the invention has the advantages that microbes for producing enzyme are tamed by utilizing the natural bacteria strains on the unsterilized carriers, so that the obtained fermentation bacteria agent is stable in microbial ecology and is capable of performing a diastatic fermentation on a cellulose substrate to produce the cellulose compound enzyme system. |
