石蕊奶

Litmus milk is a milk-based medium used to distinguish between different species of bacteria.石蕊乳是一種基於乳的培養基，用於區分不同種類的細菌。 The lactose (milk sugar), litmus (pH indicator), and casein (milk protein) contained within the medium can all be metabolized by different types of bacteria.培養基中所含的乳糖（牛奶糖），石蕊（pH指示劑）和酪蛋白（牛奶蛋白）都可以通過不同類型的細菌代謝。
Since milk is usually the first substrate used to maintain bacteria, this test allows for accurate depiction of bacterial types.由於牛奶通常是用來保持細菌的第一基質，因此該測試可以準確描述細菌的類型。 The addition of litmus, other than explaining the pH type, acts as an oxidation-reduction indicator.除了解釋pH類型外，石蕊的添加還可以作為氧化還原指示劑。 The test itself tells whether the bacterium can ferment lactose, reduce litmus, form clots, form gas, or start peptonization.測試本身告訴細菌是否可以發酵乳糖，減少石蕊，形成凝塊，形成氣體或開始肽化。
