凝乳酶

Two pairs of primers were designed based on the sequence of ovis aries preprochymosin cDNA reported in GenBank.The preprochymosin cDNA was obtained from toltal RNA isolated from the abomasum of 5-day-old Xinong Saanen Goat by RT-PCR method and then cloned successfully in E.coli.

参照GenBank登录的绵羊凝乳酶原前体cDNA序列设计引物，以新生5d的西农萨能羊皱胃组织总RNA为模版，通过RT-PCR方法获得凝乳酶原前体cDNA，克隆测序后进行序列比对。

The development of genetically engineered chymosin has been encouraged by shortages and fluctuations in cost of rennet from calves.

Rennin, an enzyme from calf stomachs, but now produced by genetically engineered micrnicroorganisms, can also be used to promote curd formation.

凝乳酶是一种从小牛胃中得到的酶，但现在通常是用基因工程微生物制得，它也能够促进凝块的形成。

The genetic material which encodes for chymosin is introduced into a micro-organism which can then be cultured to produce commercial quantities of chymosin.

遗传物质的编码为凝乳酶引入微生物，然后再培养，来生产商用数量的凝乳酶。

Today, purified chymosin is alsomanufactured through genetic modification of microorganism whenthe chymosin gene from a calf is duplicated and inserted into microbial cells.

现在，从小牛身上获得的凝乳酶基因经过复制注入到微生物细胞中后，通过微生物转基因可以生产提纯的凝乳酶。

The chymosin purified from glutinous rice wine is the reason why glutinous rice wine could coagulate Chinese royal cheese, one of traditional Chinese dairy produce.

Cheese is the fresh or mature fermented milk product made by cow or ewe milk, cream, partly degreased milk, buttermilk or the mixture of all these added with proper lactobacillus and rennin, through clabbering and whey segregating.

奶酪是以牛乳或羊乳、奶油、部分脱脂乳、酪乳或这些产品的混合物为原料，加入适量乳酸菌和凝乳酶，经凝乳并分离乳清而制得的新鲜或发酵成熟的乳制品。

The experiment selected dairy fresh milk as raw material, EZAL and MAOLL as fermentation agent, microbial rennet, swine pepsin, lamb rennet, calf rennet, papain and ficin as milk-clotting enzymes to produce hard cheese. This paper studied the physical, chemical and biochemical characteristics of different milk-clotting enzymes during the cheesemaking.
