Bacterial Culture

The Bacterial Culture is a group of bacteria that has been grown in a laboratory. A pure culture includes only one kind of bacteria, whereas a mixed culture has two or more types. If a bacterial culture is kept in the same media for too long, the cells deplete the nutrients available, exude poisonous metabolites, and ultimately die. To keep the bacterial population rising, bacterial cultures should be transferred, or subcultured, to new media on a regular basis.
