Combined with the test of All〓wden reaction and observation with SEM, the data have proved that protease SZ can digest the protein of epicuticle and then hydrolyzed the cuticle of wool, while the other proteases have no this distinctive effects, although they can confer wool bigger weight loss too. As protease SZ can digest the epicuticle and cuticle, the wool can be confered excellent antifelting property with low tenacity and elongation loss.

本文结合羊毛的阿尔瓦登反应和电镜观察，证明了绝大部分酶制剂由于不具有对羊毛鳞片表层蛋白的水解特性，因而处理后的羊毛不具有良好的防毡缩性能，而SZ酶却可对羊毛鳞片表层蛋白进行水解，进而可以对羊毛的鳞片进行有效的减量改性，使羊毛获得优良的防毡缩性能。

The reason why only when wool is pretreated with hydrogen peroxide can protease SZ confer wool excellent antifelting property is that the pretreatment can remove some lipid on epicuticle, thus the protease SZ has the possibility to digest the protein of epicuticle for no lipid's obstruction.

SZ酶之所以需在双氧水氧化预处理的条件下才能使羊毛织物获得优良的防毡缩性能，是因为双氧水预处理在打开羊毛蛋白部分交联的同时，也可去除羊毛鳞片表面部分类脂，为SZ酶进攻羊毛鳞片表层蛋白提供了可能。

The protease activity in foregut was higher than that of midgut in an acidic condition at pH 5.0-5.8, while in an alkalescence condition at pH 7.0-8.6, the protease activity was higher in midgut than that in foregut. The lipase activity of foregut was high and stable in two pH ranges: 4.2-5.0 and 6.2-7.0, and that of midgut was high at pH 3.8, while the lipase lost enzyme activity at pH over 9.0. The amylase activity was high and stable at pH 6.6-7.4 in both foregut and midgut. The cellulase activity of foregut and midgut was high and stable at pH 6.2-7.4 and 5.4-7.0 respectively.

刺参前肠蛋白酶活力在酸性环境下较中肠高，且在反应pH为5.0-5.8之间酶活力相对稳定，而中肠蛋白酶活力在碱性环境下较前肠高，且在反应pH为7.0-8.6之间酶活力相对稳定；刺参前肠脂肪酶活力随着pH的升高出现两个相对稳定的峰值，分别为4.2-5.0和6.2-7.0区间，中肠脂肪酶活力在pH为3.8时达到最大值，而在pH超过9.0明显失活；刺参前肠和中肠淀粉酶活力在pH变化时表现出相似的变化趋势，在反应pH为6.6-7.4之间酶活力较高且相对稳定；刺参前肠和中肠中纤维素酶活力在pH变化时反应不一致，前肠淀粉酶在反应pH为6.2-7.4之间酶活力较高且相对稳定，中肠纤维素酶活力在反应pH为5.4-7.0之间酶活力较高且相对稳定。

An alkaline protease Alcalase AF 2.4 L was used to hydrolyze corn gluten meal and study the effects of pH and enzyme concentration on protein conversion. The optimum technological conditions were obtained in this test as follow: hydrolyzing temperature 55℃,addition of 2 ml alkaline protease(90 947 U/ml),pH=9,concentration of substrate 0.1g/ml,hydrolysis time 1 h.

研究了碱性蛋白酶Alcalase AF 2.4L水解玉米蛋白时，pH值和酶浓度对蛋白质转化率的影响，得到了实验范围内的最佳工艺条件：水解温度55℃，碱性蛋白酶加入量2ml(90 947U/ml)，pH值9，底物浓度0.1g/ml，水解时间1h。

The results showed that:(1) The relative weight gain, special growth rate, feed conversion rate, feed protein efficiency and protein deposition rate were improved significantly (P.05) by supplementing compound acidifier in common carp diet.(2) The protease activities in the liver pancreas, fore and middle intestines increased significantly (P.05) by supplementing 0.3% compound acidifier. The activities of amylase and lipase were improved after the supplementation, but not at significant level.(3) Supplementation of compound acidifier in common carp diet did not significantly affect the fish body protein, lipid, ash, moisture contents, coefficient of fatness and viscerosomatic index.
