| Abstract: | According to the standard method from IUPAC,the activities of endo-β-1,4-glucanase,cellobiase and filter paper enzyme from Glenea cantor were analyzed and their locations were determined.Optimal pH value and optimal temperature of endo-β-1,4-glucanase were measured.The results showed that there were activities of all above three cellulases in Glenea cantor.They were mainly located in the midgut.The endo-β-1,4-glucanase had activity in a broad pH value and temperature range.Optimal pH value and optimal temperature of the endo-β-1,4-glucanase were 9.2 and 50℃,respectively. |
