| 摘 要： | 通过对脂肪酶降解壳聚糖产物的黏度测定，笔者研究了脂肪酶降解壳聚糖过程中一系列反应条件包括温度、时间、酶浓度对降解程度的影响．结果表明，最佳的降解条件是：最适宜温度60℃，最适宜的时间是5h，最佳酶量为700U／g，同时得到了相对分子质量小于10000的低聚壳聚糖．

| Abstract: | The effects of reaction temperature and enzyme concentration on the hydrolytic velocity of chitosan by eellulase were investigated. The results showed that the optimum temperature and time were 60℃ and 5 hour, respectively, the amount of 700 U/g ,at the same time by molecular weight 〈 10000 oligomerization chitosan. |
