摘要
采用DNS法测定不同pH值条件下贵州疣螈(Tylototriton kweichowoensis)消化系统不同组织中淀粉酶的活性,结果表明:贵州疣螈消化系统胃、肝、前肠、中肠、后肠淀粉酶的最适pH依次是:2.2、7.8、7.0、7.8和8.2。在最适pH下(30℃)各组织的淀粉酶活性依次25.1、110.3、53.7、58.7和43.3个活性单位。
Using DNS to mensurate the Tylototriton kweichowoensis＇ s amylase activeness under different pH conditions in the different organizations of its digestive system, the result indicates that the Tylototriton kweichowoensis digestive system： stomach, the liver, the foregnt, the midgut, and hindgut amylase＇ s most suitable pH are in turn： 2.2, 7.8, 7.0, 7.8 and 8.2.Under the most suitable pH （30℃） each organization＇s amylase activeness is in turn 25.1, 110.3, 53.7, 58.7 and 43.3 activity units.
