| 1. | Freely soluble in water and methanol , freely soluble in ethanol and acetone , and slightly soluble in toluene and chloroform 易溶于水和甲醇。并易溶于乙醇、丙酮中,微溶于甲苯和氯仿中。 |
| 2. | Apart from these , the factors involved with the enzymic properties of the immobilized papain were studied in comparison with freely soluble papain 此外,考察了影响固定化木瓜蛋白酶酶学性质的因素,并与游离酶进行了比较。 |
| 3. | It is anhydrous or the monohydrate . it is freely soluble in water and in glycerin , slightly soluble in alcohol , and insoluble in ether 白色或微黄白色结晶性粉末或颗粒,无臭,微黄,在空气中易溶于水和甘油,微溶于醇,不溶于醚。 |
| 4. | The polymyxin b sulphate is available as a freeze - dried powder freely soluble in saline solution in vial containing 500 , 000 units potency (供应的)硫酸多粘菌素b硫酸盐为冻干粉末,可任意溶于盐溶液中,每小瓶含五十万单位(效价) 。 |
| 5. | The model was based on the relationship between the concentration of freely soluble enzyme and adsorption quantity of the vector , combined with time and adsorption , some kinetic parameters ( igk , n ) related to the process were obtained by using the model 根据酶液浓度与载体吸附量的关系,结合时间与吸附量的关系,建立了freundlich等温吸附模型,并获得了该模型的动力学参数( lgk , n ) 。 |
| 6. | The results showed that thermal and storage stabilities of the immobilized papain were higher than those of the freely soluble one , and that papain directly was immobilized onto the microspheres " surface without any spare space provided a higher stability 结果表明:由于木瓜蛋白酶直接固定于微球表面而没有剩余空间,这给固定化酶提供了更高的稳定性,所以固定化木瓜蛋白酶在热稳定性与储藏稳定性方面优于游离酶。 |
| 7. | The optimum temperature , the ph and storage stability were 80 ? , 8 . 0 and 28 days respectively . the reclaimed efficiency of immobilized enzyme that is prepared by this vector is over 76 % , the michaelis - menten kinetic constants were evaluated for the immobilized and the freely soluble enzymes , they were 21 . 64147 and 7 固定化酶的最适反应温度是80 ,最适ph是8 . 0 ,操作半衰期是28天,固定化酶的酶活回收率在76 %以上,通过米氏方程测定了固定化酶和溶液酶的米氏常数,分别为21 . 64147和7 . 0836 。 |
