| Abstract: | The optimum pH for protease activity of various digestive tissues mChanna asiatica was studied. The results showed that , in the range from pH 3. 0 to pH7, 8,optimum pH of protease activi-ty for the stomach mucosa, foregut mucosa and hepatopancreas of C. asiatica adults were 6. 2, 5. 4 and 5. 4 respectively. In various digestive tissues the optimum pH for the highest activities of protease were different. |
