查询词典 sulfur ether

The different enzyme protecting agent had effected on the liquid alkaline protease under the dissimilar condition. Taking the living rate of enzyme as the target, we obtained one high effective alkaline protease stabilizing agent formula through orthogonal experiments as following: 5 mmolL^(-1) Ca(superscript 2+), 15mgmL^(-1) trimethylene glycol-single methyl ether, 0.015% 4-formyl phenyl-boron dihydroxide, 1% glycerine.

在此基础上，进行L13(3^7)正交实验，以相对酶活率为指标，考察了不同酶活性保护剂在不同条件下对液体碱性蛋白酶活力的影响，筛选到一种优质高效的碱性蛋白酶稳定剂配方为：5mmolL^(-1) Ca(上标 2+)，15mgmL^(-1)丙二醇－单甲醚，0.015% 4-甲酰苯基硼酸，1%甘油。
