Quizplus · Accepted Answer

Differential medium is designed to distinguish different types of microorganisms based on an observable change in the colonies or in the medium. This can be achieved by incorporating indicators such as dyes or enzymes that change color when certain metabolic processes occur. Examples of differential media include Mannitol Salt Agar (MSA), which differentiates between salt-tolerant and non-salt-tolerant bacteria, and MacConkey Agar, which distinguishes between lactose fermenters and non-fermenters.
