A colony that arises form a single mother cell. The colony should not touch another colony. A pure colony consists of 50-72 generations of cells arising from a single mother cell.

Why colony represent a pure culture?
The colony started from one single microbe that divided and divided until it formed what we call a colony of all the same bacteria. By selecting that colony we can be sure that its is pure and will grow only into a pure culture. Be sure to select on that is isolated so that you will not pick up a contaminate.
Why can a single colony on a plate be used to start a culture?

What are the advantages of obtaining pure culture in microbiology laboratory?
Obtaining pure cultures in a microbiology laboratory allows for the study of specific microorganisms without interference from other species, which is essential for accurate identification and characterization. It facilitates the examination of the organism's morphology, metabolic activities, and genetic properties, leading to clearer insights into its behavior and potential applications. Additionally, pure cultures are crucial for conducting controlled experiments, testing antibiotic susceptibility, and producing vaccines or other bioproducts. Overall, pure cultures enhance the reliability and reproducibility of microbiological research.
What is the value of petri plates in microbiology?
It gives microbiologists a way to grow bacteria on a solid medium. This is important if you want to be able to obtain a pure culture, without a solid medium to grow bacteria it would be nearly impossible. On a solid media a single colony can be isolated and used to innoculate a further plate or broth culture. All the bacteria present in a colony should be decendents of a single organism and so be genetically identical. To obtain a pure culture in liquid media, you would have to do numerous serial dilutions which is very labor intensive compared to streaking a solid medium. Even after many serial dilutions there would be no way to ensure a pure culture.

Why would you assume that an isolated colony is a pure colony of that microorganism?
Because bacterial cells reproduce and form identical daughter cells. Therefore, a single cell that is isolated away from the rest of the mixed bacterial culture will reproduce a colony of cells identical to itself. You will know that it is only that certain type of bacteria with none others mixed in, or pure :)

Why restreak isolated colony?
Restreaking an isolated colony helps to obtain a pure culture by separating individual bacterial cells and preventing contamination. It also allows for further characterisation of the colony and ensures reproducibility in future experiments.

What is a colony in microbiology?
A colony is a group of identical bacteria (clones) which grow together into a visible cluster. Generally, a colony is grown on an nutrient agar plate (on a petri dish with bacteria food in it) such that it is large enough to see the bacteria. An additional type of colony is a "microcolony" which is a term used for a group of the same bacteria which grown in the dirt.
