| 摘 要： | 通过改变反应温度分析了一定pH值下沙塘鳢(Odontobutis obscura)三种主要消化酶活性的变化。结果表明:pH6.0时,沙塘鳢肝胰脏、胃、肠道淀粉酶的最适温度分别为25℃、35℃、25～30℃;肝胰脏和肠道pH7.5时,胃pH2.0时,蛋白酶的最适温度分别为40℃、35℃、35℃;pH7.5时,肝胰脏、胃、肠道脂肪酶的最适温度分别为30℃,40℃,25℃。淀粉酶和脂肪酶活性分布是肝胰脏最高,胃次之,肠道最低;蛋白酶活性分布是胃最高,肝胰脏和肠道稍低。

| Abstract: | The effect of different reaction temperature on activities of three digestive enzymes in Odontobutis obscura were examined.The results showed:the optimum temperature of amylase in the liver,stomach and intestine were 25,35,25～30 ℃ respectively when the pH value was 6.0;the optimum temperature of protease were 40,35,35 ℃ respectively when the pH value was 7.5 in the liver and intestine and 2.0 in stomach.The optimum temperature of lipase were 30,40,25℃ respectively when the pH value was 7.5.The activities of amylase and lipase were liver>stomach>intestine,and the activities of protease were stomach>liver>intestine. |
