| 摘 要： | 对月鳢(Channa asiatica)消化系统不同部位淀粉酶和脂肪酶活性的最适pH值进行了研究,结果表明,在pH值5.8～7.8范围内,月鳢成鱼胃粘膜组织、前肠粘膜组织和肝胰脏淀粉酶的适宜pH值分别为7.4～7.8、7.8和7.8,对于脂肪酶则分别为7.4、6.6和7.0。不同消化部位的淀粉酶和脂肪酶活性的最适pH值有所差异。

| Abstract: | The optimal pH for amylase and lipase activities of various tissues in channa asiatica were studied. Within the range of pH 5.8～7.8, the results showed that the optimal pH for amlyase in the stomach mucosa, foregut mucosa and hepatopancreas were 7.4～7.8, 7.8 and 7.8 respectively, and for amylase were 7.4, 6.6 and 7.0. In various digestive tissues the optimal pH for the highest digestive enzyme activities existed some difference. |
