| 摘 要： | 测定了军曹鱼（Rachyceruton canadum）的胃、幽门盲囊、肠等消化组织中淀粉酶在不同pH值下的活力及在最适pH值下底物体积分数、盐度对其活力的影响。结果表明，胃、幽门盲囊、前中肠、后肠的淀粉酶的最适pH值分别是6．0，7．0，5．8和7．0；其最适底物体积分数分别为0．056％．0．056％，0．048％和0.064％；其最适盐度为28。

| Abstract: | The activity of amylases taken from the stomach, pancreas and intestine of Rachycentron canadum was determined. The results stowed that the most optimum pHs for stomach, pancreas ,fore - intestine, mid - hind - intestine were 6.0, 7.0, 5.8 and 7.0 respectively; the most optimum amylum concentrations were 0. 056%, 0. 056%, 0. 048% and 0. 064% respectively;and the most optimum salinity was 28. |
