MacConkey Medium 馬康基氏培養基

MacConkey Agar/Broth 馬康基氏 瓊脂/培養液

 
為一種細菌繁殖營養成分,對革蘭氏陰性菌有效,
由於它的特殊成分 ( Neutral red [ 中性紅 ] / Bromo cresol purple [ 溴甲酚紫 ] pH指示劑 ),
可以辨別會利用乳糖發酵 和 無法利用乳糖發酵的細菌。

在馬康基氏瓊脂上
          會利用乳糖發酵的細菌的顏色為紫紅色,
   而無法利用乳糖的細菌則呈現橙黃色,
   在於微生物發酵乳糖產生 ,會導致酸鹼值(pH)的差異性。


可以利用乳糖發酵的細菌就會是紫紅色,如:大腸桿菌Escherichia coli / Coliform ..等等。
無法利用乳糖發酵的細菌就會是橙黃色,如:沙門氏菌Salmonella ..等等。

Neutral red / Toluylene red [ 中性紅 ] pH指示劑(酸鹼指示劑):
            會因酸鹼值(pH)而改變顏色,
Bromo cresol purple [ 溴甲酚紫 ] pH指示劑(酸鹼指示劑):
            會因酸鹼值(pH)而改變顏色,
            低於pH 6.8時呈紫紅色,高於pH 5.2時呈橙黃色。

MacConkey培養基的配方包含:
蛋白腖(Peptone )
乳糖(Lactose)
膽鹽(Bile salts)
氯化鈉(Sodium chloride)
結晶紫(Crystal violet )
/ 牛磺膽酸鈉(Sodium taurocholate )
中性紅(Neutral red )
/ 溴甲酚紫 (Bromo cresol purple )
瓊脂[洋菜膠](Agar )
蛋白腖,胰蛋白腖和明膠蛋白腖提供微生物生長所需的氮,碳源
乳糖供可發酵的碳水化合物。
膽鹽 促進幾種腸道菌的生長,抑制大部分革蘭氏陽性菌的生長。
氯化鈉提供細胞轉運用的鹽離子和滲透壓平衡功能。
結晶紫染色 抑制特定革蘭氏陽性菌。
牛磺膽酸鈉 抑制特定革蘭氏陽性菌。
中性紅染色 介質中的pH指示劑染料,在酸性條件下變橙黃。
溴甲酚紫是 介質中的pH指示劑染料,在酸性條件下變橙黃。
