| 摘 要： | 盾壳霉几丁质酶和葡聚糖酶酶动力学性质研究表明:几丁质酶和葡聚糖酶的酶促反应,在本试验计量范围内,其反应速度与酶量和底物浓度均呈正相关,但两种酶促反应适宜的温度和pH值有较大差。几丁质酶降解几丁质的最适反应温度为50℃,最适pH值为8.0,葡聚糖酶降解葡聚糖的最适反应温度为60℃,最适pH值为3.0。

| Abstract: | The study on characture of enzmye dynamics of chitinase and glucanase from Coniothyrium minitans showed that reactive rate using chitinase and dextranase was positive correlation with enzyme quantity and substrates.But the temperature and pH of these two reactions were more different.The optimum temperature of chitinase degrading chitin is 50 ℃,and the most suitable pH is 8.0.The optimum temperature of dextranase degrading dextran is 60 ℃,and the most suitable pH is 3.0. |
