Pure culture – is a container of medium that grows only a single known species or type of microorganism. Contains only one species or type of microbe.

Axenic culture – culture that is free of other living things except the one being studied (commonly used in laboratory for study).
- A standard method of preparing a pure culture is subculture or make a second level culture from a well isolated colony.
- A tiny bit of cells is transferred into a separate container of media and incubated.

A mixed culture is a container that holds two or more easily differentiated species of microorganisms.
