| 摘 要： | 绿色木霉3.3744菌株所产纤维素酶对草稿纸、复印纸、滤纸、包装材料和新闻纸等五种类型废纸有不同的降解效果。结果表明:包装材料作为底物时的纤维素酶酶活始终较高,因而最终降解效果也最好,酶解4小时后酶活仍为2.72U/mL。就酶解速度来说,以新闻纸为底物时最高,在酶解1小时后酶活力即达2.52U/mL。液体培养所得纤维素酶活力在2～3天时间达到最高,其中以打印纸和新闻纸作为碳源时纤维素酶活力最高,在三天后分别达到4.31U/mL和3.64U/mL。

| Abstract: | Biodegradation of scratch paper、 duplicating paper、 filter paper、 packaging materials and newspaper by cellulase from Trichoderma viride 3.3744 is different.The result is：the cellulase activity of packaging materials is higher than other materials all along,so its ultimate degradation effect is the best,the cellulase activity is still 2.72 U/mL after 4 hours.As to enzymolysis rate,newspaper is the best,the cellulase activity is already 2.52 U/mL after 1 hours. The cellulose activity reached to the highest by submerged culture after 2 to 3 days,among which duplicating paper and newspaper is the best,the cellulose activity reached to 4.31U/mL and 3.64U/mL. |
