温度、pH值对团头鲂肝胰脏主要消化酶活性的影响

Effect of Different Temperature and pH on Digestive Enzyme in Megalobrama amblycephala

蛋白酶、淀粉酶和脂肪酶的活性直接影响动物对食物的消化作用。通过设置不同的pH和反应温度,来确定团头鲂蛋白酶、淀粉酶和脂肪酶的最适活性。结果表明,在不同温度条件下,测定团头鲂淀粉酶、脂肪酶和蛋白酶的最适温度为50℃、50℃和40℃。团头鲂淀粉酶、脂肪酶和蛋白酶最适pH分别为7.0,5.5和7.2。

By changing temperature and pH,the amylase,lipase and protease of Megalobrama am blycephala were studied. The results shown that the optimum temperature of amylase ,lipase and pro tease was 50℃, 50 ℃ ,40 ℃. The results showed that ： Under the condition of different pH ,The re suhs shown that the optimum pH of amylase ,lipase and protease wasT. 0,5.5,7.2.
