A strain producing cellulases were selected and isolated from wide forest soil by cultured on plates of Congo red dying,in liquid medium with filter paper,then fermented in liquid medium.Different pH and temperature and were performed to find the optimal condition of enzyme activity.The results showed that the optimal reaction conditions of CMCase were 50℃,pH 2.8,the enzyme activity was very stable under the temperature ranging between 30-50℃.The optimal conditions for the enzyme reactivity of FPase were pH...
