What is the colony configuration of E coli?

The colony configuration of Escherichia coli (E. coli) typically appears as smooth, round, and convex colonies on solid media. They are often characterized by a moist, glistening surface and can range in color from off-white to yellowish. Colonies usually measure 1-3 mm in diameter and may exhibit a slightly opaque appearance. E. coli colonies are generally well-defined and may have entire edges.
