Differential media: 1. Allow the growth of fastidious microbes through the addition of certain growth enhancers 2. Support the growth of one type or group of microbes, but not another 3. Support the grouping of microbes based on different characteristics demonstrated in the media 4. Support the growth of most nonfastidious microbes

3. Support the grouping of microbes based on different characteristics demonstrated in the media.

Explanation:

Differential media is the growth medium for the growth of bacterial culture. This media consists of specific ingredients that are necessary for distinguishing the selected species by visual examination. The differential media is used to distinguish between the closely related organism and differentiating them with other organisms.

Due to the addition of some dyes or chemicals that are specific to some of aids in observing the bacteria in the medium and their growth pattern can be identified. This kind of macroscopic differentiation of the bacteria shows the ability of the bacteria to conduct the biochemical processes.
