石蕊奶

Litmus milk is a milk-based medium used to distinguish between different species of bacteria.石蕊乳是一种基于乳的培养基，用于区分不同种类的细菌。 The lactose (milk sugar), litmus (pH indicator), and casein (milk protein) contained within the medium can all be metabolized by different types of bacteria.培养基中所含的乳糖（牛奶糖），石蕊（pH指示剂）和酪蛋白（牛奶蛋白）都可以通过不同类型的细菌代谢。
Since milk is usually the first substrate used to maintain bacteria, this test allows for accurate depiction of bacterial types.由于牛奶通常是用来保持细菌的第一基质，因此该测试可以准确描述细菌的类型。 The addition of litmus, other than explaining the pH type, acts as an oxidation-reduction indicator.除了解释pH类型外，石蕊的添加还可以作为氧化还原指示剂。 The test itself tells whether the bacterium can ferment lactose, reduce litmus, form clots, form gas, or start peptonization.测试本身告诉细菌是否可以发酵乳糖，减少石蕊，形成凝块，形成气体或开始肽化。
