采用酪蛋白为原料,经过消化、脱色、过滤浓缩、喷雾干燥而得到的一种浅黄色至类白色的干燥粉末。易溶于水,水溶液呈淡黄色。酪蛋白又是从牛奶中提取的一种营养价值很高的磷蛋白,是生产蛋白胨常用的原料。用此原料生产的成品,其氨基酸比较齐全,特别是色氨酸的含量比较高。所以它在细菌生化试验中最适宜于做靛基质和糖发酵试验。

It is a pale yellow to off-white dry powder obtained by using casein as raw material, followed by digestion, decolorization, filtration, concentration and spray drying. It is readily soluble in water, and its aqueous solution is pale yellow. Casein is a high-nutrition phosphoprotein extracted from milk and a common raw material for producing peptone. The finished product made from this raw material has a relatively complete amino acid profile, especially with a high content of tryptophan. Therefore, it is most suitable for indole production tests and sugar fermentation tests in bacterial biochemical assays.
Directions for Use:
As a culture medium raw material, fully dissolve it and use after sterilization.
