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.
What else can I help you with?
Does each discrete colony represent the growth of one cell on an agar plate?
This is one part of a two part answer. Q: Does each discrete colony represent the growth of one cell? Explain your answer. Why can a single colony on a plate be used to start a pure culture? A: No because a discrete colony is the growth of the descendants of a single cell. The cell will self replicate it self on the growth medium to produce more copies of it self thus creating a colony. A single colony has many cells in the colony. Cells from the colony can be extracted and then placed in a pure culture for better growth. A.C.
What type of culture technique would be used to obtain a pure culture?
To obtain a pure culture, a technique called streak plate method is commonly used. This technique involves streaking a sample on an agar plate in a way that isolates individual colonies, allowing for the growth of pure cultures. Subsequent subculturing from a single isolated colony can help to ensure a pure culture.
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.
Did you get a pure culture in your subculture and how to know?
Ensuring that your culture is pure is very important to getting accurate results of your gram stain. One way to tell if your culture is pure is to test both the control and the experiment cultures. If you get a different result than the one you were expecting, you might have a corrupted culture. Making sure that you have several items of each is helpful, as well.
When more than one colony type appears in a pure culture what are the most likely sources of the extraneous organisms?
The most likely sources of extraneous organisms in a pure culture are contamination from the environment (such as air, equipment, or surfaces), contamination during sample collection or handling, or unintentional mixing of different cultures. These extraneous organisms may have different growth requirements or characteristics, leading to the appearance of multiple colony types.

What is a pure culture?
The culture which contain an organism (bacterial colony) which you are required to grow in a broth media that is a media lacking solidifying agent agar. A pure culture should not contain other bacterial or fungal cells in it except the required or cultured one
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 :)
When more than one colony type appears in a pure culture what are the mostly likely sources of extraneous organisms?
The most likely sources of extraneous organisms in a pure culture include contamination from the environment, improper handling or aseptic technique during subculturing, or accidental introduction of organisms from contaminated equipment or reagents. These sources can introduce multiple types of colonies in what should be a pure culture.
What is a broth culture?
The culture which contain an organism (bacterial colony) which you are required to grow in a broth media that is a media lacking solidifying agent agar. A pure culture should not contain other bacterial or fungal cells in it except the required or cultured one
What is a pure colony in microbiology?
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.
When more than one colony type appears in a pure culture what are the most likely sources of the extraneous organisms?
The most likely sources of extraneous organisms in a pure culture are contamination from the environment (such as air, equipment, or surfaces), contamination during sample collection or handling, or unintentional mixing of different cultures. These extraneous organisms may have different growth requirements or characteristics, leading to the appearance of multiple colony types.
