说明

胰蛋白胨是一种从植物来源获得的通用生长蛋白胨,是酪蛋白酶消化的无肉替代品。 它被用作培养基中的氮源,用于分离和培养挑剔和非挑剔的细菌、真菌和一些原生动物。 它是一种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。 它是酪蛋白胰消化产生的氨基酸和肽的优质来源。

胰蛋白胨推荐用于实验室培养基和发酵,并已用于抗生素、毒素和酶生产。 它还用作疫苗生产中需要高游离氨基酸含量的营养素。 胰蛋白胨也可用于 -80°C 的 STGG(脱脂牛奶、胰蛋白胨、葡萄糖、甘油)培养基,用于保存肺炎链球菌、流感嗜血杆菌和卡他莫拉菌分离物至少 3 年。

一般描述

Tryptone is a general-purpose growth peptone obtained from vegetable source and meat-free alternative to enzymatic digest from casein. It is used as a nitrogen source in culture media formulated for isolating and cultivating fastidious and non-fastidious bacteria, fungi, and some protozoa. It is a refined hydrolysate with high solubility and is used as a microbiological nutrient in laboratory media and fermentations. It is a high-quality source of amino acids and peptides produced by the pancreatic digestion of casein.
 

应用

Tryptone is recommended for laboratory media and fermentation and has been used in antibiotics, toxins, and enzyme productions. It is also used as a nutrient in vaccine production where a high free amino acid content is required. Tryptone may also be used in STGG (skim milk, tryptone, glucose, glycerol) medium at -80°C, which is used to preserve Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis isolates for at least 3 years.
