2022年8月10日 · MacConkey agar is a selective and differential media used for the isolation and differentiation of non-fastidious gram-negative rods, particularly members of the family Enterobacteriaceae and the genus Pseudomonas.

MacConkey agar is a selective and differential culture medium for bacteria. It is designed to selectively isolate gram-negative and enteric (normally found in the intestinal tract) bacteria and differentiate them based on lactose fermentation. [1] Lactose fermenters turn red or pink on MacConkey agar, and nonfermenters do not change color.

MacConkey agar (MAC) is a selective and differential bacterial culture media. MacConkey medium is selective for gram-negative bacteria and differentiates the gram-negative bacteria based on lactose metabolism.

2024年9月10日 · MacConkey agar (MAC) is a bacterial culture medium named after bacteriologist Alfred T. MacConkey (1861-1931). MacConkey agar is a selective and differentiating agar that only grows gram-negative bacterial species; it can further differentiate the gram-negative organisms based on their lactose metabolism.[1]

MAC（麦康凯琼脂），是一种 培养基，用于 分离培养，主要成分为 蛋白胨 、脙胨、猪 胆盐 、 氯化钠 、 琼脂 、 乳糖 等。 麦康凯琼脂 培养基 (Mac conkey,MAC)简称：Mac 培养基。 主要成分： 蛋白胨 、脙胨、猪 胆盐 (或牛、羊胆盐) 氯化钠 、 琼脂 、 乳糖 、1% 结晶紫 水溶液、0.5% 中性红 水溶液. 麦康凯 平板的原理：利用胆盐来抑制 革兰阳性细菌 的生长,而对 伤寒 等 沙门菌 有促进生长的作用。 利用乳糖发酵,中性红的颜色可把分解乳糖和不分解乳糖的细菌区别开。 沙门菌 …

2021年3月22日 · MacConkey agar is a selective and differential culture medium for bacteria. It is designed to selectively isolate Gram-negative and enteric (normally found in the intestinal tract) bacilli and differentiate them based on lactose fermentation. Lactose fermenters turn red or pink on McConkey agar, and nonfermenters do not change color.

2024年4月11日 · MacConkey Agar is a widely used culture medium in microbiology laboratories. It was developed by Alfred Theodore MacConkey in 1900, making it the first solid differential media to be formulated in the 20th century.

2022年5月7日 · MAC is a modification of Neutral Red Bile Salt Agar developed by MacConkey. It was one of the earliest culture media for the cultivation and identification of enteric organisms from clinical specimens as well as food and water. It is a selective, differential, and indicator medium because of the following properties-

MacConkey Agar is a selective and differential medium used for the isolation and differentiation of non-fastidious Gram-negative bacilli, in particular members of the Enterobacteriaceae family and the genus Pseudomonas. Crystal violet dye and bile salts stop the growth of …
