Sep 26, 2022 · 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]

Aug 10, 2022 · MacConkey agar is used for the isolation of gram-negative enteric bacteria. It is used in the differentiation of lactose fermenting from lactose non-fermenting gram-negative bacteria. It is used for the isolation of coliforms and intestinal pathogens in water, dairy products and biological specimens.
Jan 18, 2023 · E. coli isolates were identified based on colonial morphology and with gram staining. Under light microscopy, E. coli cells are typically gram negative and are short and rod-like in appearance. Conventional biochemical tests, which included catalase and oxidase tests, were used for further characterization of the bacteria, according to methods ...
