Question
Chapter 6, Problem 19CT
Summary Introduction
To explain:
Whether the MacConkey agar is suitable for gram-positive or gram-negative bacteria after examining the ingredients present with reference to Table 6.4 and p.176.
Introduction:
The MacConkey agar serves as an indicator, differential as well as a selective medium. The source of carbohydrate in this medium is lactose. This medium was formulated by Alfred Theodore MacConkey; therefore, the media was named as MacConkey agar.
