中文摘要：测定了军曹鱼(Rachycentroncanadum)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。

外文摘要：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.
