| 摘 要： | 试验研究了pH值对黑鲷胃、肠及肝胰脏中蛋白酶、淀粉酶和脂肪酶等3种主要消化酶活力的影响。结果表明:在黑鲷正常的消化道酸碱条件下（胃pH值2.5,肠pH值7.5）,蛋白酶活力大小顺序为:胃>肠>肝胰脏;淀粉酶活力大小顺序为:肝胰脏>肠>胃;脂肪酶大小顺序为:肠>肝胰脏>胃。胃蛋白酶、淀粉酶和脂肪酶的最适pH值分别为2.0,5.0和4.0,均在酸性范围;肠蛋白酶、淀粉酶、脂肪酶的最适pH值分别是7.0,7.0,7.5,肝胰脏蛋白酶、淀粉酶、脂肪酶的最适pH值分别是7.5,7.0,7.0,均为中性或略偏碱性。

| Abstract: | In this paper,the effects of pH value on the main digestive enzyme activities in intestinal canal and hepatopancreas in Sparus macrocephalus were studied. The results showed:in normal pH value in Sparus macrocephalus,the trend of protease activities of the intestinal canal and hepatopancreas are stomach>intestine>hepatopancreas,the trend of amylase activities of the intestinal canal and hepatopancreas are hepatopancreas>intestine>stomach, and the trend of lipase activities of the intestinal canal and hepatopancreas are intestine>hepatopancreas>stomach. The optimum pH values of stomach, intestine and hepatopancreasfor protease are 2.0,7.0,7.5 respectively,for amylase are 5.0,7.0,7.0 ,and for lipase are 4.0,7.5,7.0 |
