中文摘要：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。

外文摘要：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.
