栉孔扇贝蛋白酶和淀粉酶活力的初步研究
The Studies on the Activities of Protease and Amylase of Chlamys (Azumapecten) farreri
【摘要】 研究了栉孔扇贝(Chlamys(Azumapecten)fareri)两种主要消化酶——蛋白酶和淀粉酶与温度和pH的关系。结果表明:在4.8℃与75℃之间蛋白酶的最适温度为60℃,在5℃与60℃之间淀粉酶的最适温度为25℃;蛋白酶的最适pH值有两个,分别是2.61和7.77,淀粉酶的最适pH值为6.5。栉孔扇贝蛋白酶和淀粉酶的活性与酶本身的性质及栉孔扇贝的生理状态有关
【Abstract】 This paper studies the activities of protease and amylase on Chlamys (Azumapecten) farreri . The results indicate that the optimum temperatures of protease and amylase are 60℃ and 25℃, respectively. The optimum pH valuses of protease are 2.61 and 7.77 , and that in amylase is 6.45. There are two optimum pH valuses in protease of Chlamys (Azumapecten) farreri .
