Abstract: Abstract: From the soil, garbage and rotting leaves through such as Congo red medium, carboxymethyl cellulose medium and so on mediums screen out of L-1, L-3, L-4, L-5, L-6, L-2 6 strains. Then use those six strains to individually ferment the medium which is composed of Camellia cake as the main nutritional components. By comparing the solid-state fermentation of enzyme activity，can know that L-1, L-3, L-4 three kinds of strains can be used as alternate strains which can efficiently decompose the cellulose of Camellia cake. And by comparing the significant analysis about the Glucanase Exonuclease、the Glucanase enzyme and the total activity of three alternative strains, can know that L-3 strain is the best strains of efficient cellulase degradation. And this kind of strains is identified belonging to Penicillium.
