【摘要】 池养鳗鲡禁食６ｈ后解剖，收集胃、前肠、中肠和后肠，测定其消化酶活力。结果表明：胃组织蛋白酶显著高于肠组织蛋白醇，且前肠＞中肠＞后肠，肠组织淀粉酶活力前肠＜中肠＜后肠。肠淀粉酶与肠蛋白酶最适ｐＨ分别为７．６与７．８，相应最适底物浓度为１％与０．５％～１．０％，ＮａＣｌ０．０５ｍｏｌ／Ｌ对肠淀粉酶具有充分的激活效应。更多还原

【Abstract】 The stomaches,foreguts,midguts,hindguts were collected from eels with six hours’no feeding and their digestive enzyme activities were assayed.The results showed:the protease activity of the stomach was significantly higher than that of the intestine.The trend of protease activities of the intestine were foregut>midgut>hindgut,and the trend of amylase activities of the intestine were foregut<midgut<hindgut.The optimum pH value for amylase and protease were respectively 7.6 and7.8, and the optimum substrante’s concentrations were 1% and 0.5% ～1.0% each 0.05 mol/L NaCl was enough to activate the amylase of the intestine.更多还原
