NOVELTY - Cellulase production for high-efficiency hydrolysis of a special vegetable fiber, involves: (1) selecting substrate; (2) activating and culturing cellulase-producing bacteria into a medium; (3) inoculating the cellulase-producing bacteria into a cellulase-producing culture medium, and inducing the cellulase by using the natural vegetable fiber such as bagasse as the substrate; fermenting to produce the cellulase; taking fermentation liquor out; and (4) filtering the fermentation liquor, performing salting-out, and dialyzing to form a crude cellulase solution.    USE - The method is useful for cellulase production for high-efficiency hydrolysis of a special vegetable fiber (claimed).    ADVANTAGE - The method for producing the cellulase for high-efficiency hydrolysis of the special vegetable fiber has the advantages of simplicity and convenience in operation and simplicity in process, and can provide a guiding principle for the industrial production of the natural vegetable fiber degrading cellulase.    DETAILED DESCRIPTION - Cellulase production for high-efficiency hydrolysis of a special vegetable fiber, involves: (1) selecting substrate: taking special plant fiber as the substrate; (2) activating and culturing cellulase-producing bacteria into a medium, standing to obtain cellulase producing strain activating and culturing solution; (3) inoculating the cellulase-producing bacteria into a cellulase-producing culture medium, and inducing the cellulase by using the natural vegetable fiber such as bagasse as the substrate; fermenting to produce the cellulase; taking fermentation liquor out; and (4) filtering the fermentation liquor, performing salting-out, and dialyzing to form a crude cellulase solution, where the culture medium is as follows: glucose 2-6 g/L, inducer 1-3 g/L, microcrystalline cellulose 2-3 g/L, peptone 2 g/L, ammonium sulfate ((NH4)2SO4) 2-3 g/L, potassium dihydrogen phosphate (KH2PO4) 3-4 g/L, urea 0.4-0.6 g/L, calcium chloride dihydrate (CaCl2.2H2O) 0.6-1.0 g/L, magnesium sulfate heptahydrate (MgSO4.7H2O) 0.4-0.8 g/L, ferrous sulfate heptahydrate (FeSO4.7H2O) 0.01-0.04 g/L, hydrated manganese sulfate (MnSO4.H2O) 0.001-0.004 g/L, zinc sulfate heptahydrate (ZnSO4.7H2O) 0.002-0.004 g/L, cobalt chloride hexahydrate (CoCl2.6H2O) 0.004-0.008 g/L, Twee-80 0.3-0.5 g/L, the rest is water, pH 5.0.
