MacConkey Agar - Purpose, Test and Results - (2021 - Updated), MacConkey Agar: Composition, Uses, Colony Characteristics.
Macconkey medium is used for the selective and differential growth of gram negative bacteria. The medium consists of ingredients such as peptone, lactose , bile salt, water, agar , etc. The lactose component of the agar is used as the source of fermentable carbohydrate and also serves to differentiate between lactose fermenting bacteria and.
22/03/2021 ÿú Lactose ? The Lactose present in the MacConkey Agar Medium (MAC) provides a rich source of carbohydrate for the rapid growth of the Bacterial cell and is the basis of making the MAC a differential medium, categorizing the bacteria into Lactose and Non-Lactose fermentors.
