Abstract:: The ability of six kinds of edible mushroom, Russula delica Fr，Flammulina velutipe，Lentinus javanicus，Bamboo-sun，Russula lepida and Abalone mushroom to produce cellulase were compared by using the Congo red saucer rapid screening method.Meanwhile，the optimal fermentation cnditions were optimized.The results showed that the Russula lepida appeared the most transparent rings for 20 mm in diameter.Among four kinds of carbon sources，CMC-Na，bean dregs straw powder，glucose，the bean dregs an promote the Russula lepida to produce cellulase.The optimal Femrentation conditions for the Russula lepida to produce cellulase was shaking speed 105 r/min，initial pH 5.4，time 72 h，temperature 26℃。
