Culturing bacteria culture media culture media is the food used to grow and control microbes colony streaking leads to to the isolation of individual colonies. Later in this course simpler methods for isolation of a pure culture include: (i) spread plating on solid agar medium with a glass spreader and (ii) streak plating with a loop the purpose of spread plating and streak plating is to isolate individual bacterial cells (colony-forming units) on a nutrient medium. The purpose of streaking bacteria for isolation is to create a region in which the bacteria are so dilute that when each bacterium touches the surface of the agar, it is far enough away from other.
