Bacterial Colony Isolation on Agar Plate - Microbiology Lab Technique #177367 (License: Personal Use)

This artistic illustration shows a Petri dish containing a pink agar medium with purple streaks representing inoculation lines and scattered yellow dots indicating isolated bacterial colonies. The pattern reflects the quadrant streaking method used to dilute and separate microbes for obtaining pure cultures. The soft watercolor style emphasizes educational clarity over photorealism.

Used in educational materials, microbiology textbooks, or lab protocol guides to demonstrate streak plate technique; matches user intent for learning microbial isolation methods or preparing teaching visuals.
