What Is Differential Media - Differential media, unlike selective media, does not kill organisms. Web differential media are media that make it easy to distinguish colonies of different bacteria by a change in the color of the colonies or the color of the medium. Web differential media takes advantage of biochemical properties of target organisms, often leading to a visible change when growth of target organisms are present. It indicates if a target organism is present. Blood agar allows for the growth of most types of bacterial organisms, but each organism’s ability to lyse red blood cells displays differently, which gives the microbiologist clues to its identification. Web blood agar is differential media because 3 different types of hemolysis, or lysing of red blood cells, can be seen on this plate. Learn how differential media work, see examples, and compare them with other types of media used for bacterial growth. Web differential media contain compounds that allow groups of microorganisms to be visually distinguished by the appearance of the colony or the surrounding media, usually on the basis of some biochemical difference between the two groups.
