Generally, a colony is grown on an nutrient agar plate (on a petri dish with bacteria food in it) such...Labor activities among worker bees depend primarily on the age of the bee but vary with the needs of the colony. Reproduction and colony strength depend on the queen, the quantity of food stores, and the size of the worker force. As the size of the colony increases up to a maximum of about 60,000 workers, so does the efficiency of the colony. Still, recognizing differences in colony morphology is useful when trying to isolate bacteria and also when plates of pure culture have become contaminated.

When microorganisms are cultivated in the laboratory, a growth environment called a medium is used. The medium may be purely chemical (a chemically defined medium), or it may contain organic materials, or it may consist of living organisms such as fertilized eggs. Microorganisms growing in or on such a medium form a culture.Isolated Colonies. What is an isolated colony? When you inoculate your media, you introduce bacterial cells into a nutrient-rich environment. The objective is to encourage those bacterial cells to divide and multiply their numbers.
