What is a bacterial colony?
Quick Answer
A bacterial colony is a visible cluster of bacteria growing from a single cell or a small group of cells on a solid surface. Colonies can differ in size, shape, color, and texture.
The Full Story
In the lab, a bacterial colony usually appears as a visible spot on an agar plate after cells have multiplied repeatedly. Because colonies often come from one original cell, they can represent a clone with similar genetic traits. Microbiologists use colony appearance to help identify or compare bacteria. Colony morphology includes features such as margin, elevation, color, and surface texture.
