一般描述
胰蛋白胨是一种通用的生长蛋白胨，通过用蛋白酶胰蛋白酶消化酪蛋白而产生，并可用作分离和培养苛养和非苛养细菌、真菌和一些原生动物的培养基的氮源。它是一种具有高溶解度的精制水解产物，在实验室培养基和发酵中用作微生物营养物质。它是胰酶消化酪蛋白产生的优质氨基酸和肽源。
应用
胰蛋白胨建议用于实验室培养基和发酵，并已用于抗生素、毒素和酶生产。在需要高游离氨基酸含量的疫苗生产中，它也被用作一种营养素。在-80℃下，胰蛋白胨也可用于STGG（脱脂乳、胰蛋白胨、葡萄糖、甘油）培养基，其至少能将肺炎链球菌、流感嗜血杆菌和卡他莫拉菌分离株保存3年。

Fructans are an important nonfiber carbohydrate in cool season grasses. Their fermentation by ruminal microbes is not well described, though such information is needed to understand their nutritional value to ruminants. Our objective was to compare kinetics and product formation

The availability of rumen-degradable protein (RDP) changes the use of carbohydrates by ruminal microbes. However, the effects of RDP on the simultaneous use of carbohydrate and formation of microbial products are not well described, although such information is needed to

Current feeding systems are based on the assumption that the AA profile of rumen undegraded protein is similar to that of the original feed. The objective of this experiment was to determine rumen bacterial degradation of individual essential AA in

In STGG (skim milk, tryptone, glucose, glycerol) medium at -80 degrees C, Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis isolates survived for at least 3 years, and the same species have survived in nasopharyngeal swabs for at least 1.5 years.
