Selective Culture Media Purpose

To differentiate microorganisms based on their unique characteristics, inhibiting some while allowing others to grow.

Predicting Growth Pattern

The Gram stain reaction helps determine an organism's cell wall structure, influencing its growth on different media.

Differential Culture Media

Differential media causes a visible color change in response to the metabolic activity of different microorganisms.

Using Multiple Culture Media

Using multiple culture media plates aids in the identification process by observing different growth patterns and characteristics of microorganisms.
