There are the 5 “I’s”
1. Inoculate
2. Incubate
3. Isolation
4. Inspection
5. Identification
1. Take a sample from the mouth using aseptic techniques (meaning don't cross contaminate with you own bacteria).
2. Inoculate a medium of some sort. Usually a plate called a streak plate is used. It has nutrient agar in it. It looks a little like vey stiff Jell-O. Spread the sample using a loop or 'hockey stick' using aseptic techniques.
3. Let it grow in an incubator. Set (usually) at body temperature. The plate is always placed what you would call upside down. Leave it there for 24-36 hours.
4. Open plate (aseptically) and see what is growing there. If something has you attention, use a probe (aseptically) to take a bit and put into a growth medium (usually in this case a liquid). Leave for a time and then replate.
5. The ID part means using a microscope to see the basic shapes, and also using differential media to further ID. This can mean reincubation and can take several days.
What else can I help you with?
Why dilution is a common approach employed by any pure culture technique?
the main purpose of this is to grow and isolate all bacteria present in an infection, to determine which of the bacteria that grew are most likely causing the infection and which are likely colonizers.
Why is it necessary to isolate individualcolonies from a mixed growth?
In order to identify any of the species in a mixed culture, you first have to isolate individual colonies and grow them in a pure culture. You can't perform tests to identify bacteria in a mixed culture.
Why obtain pure culture of bacteria from a mixed culture?
i obtain pure culture of bacteria from a mixed culture for obtain pure one bacterial culture
Is pure culture having same meaning of microbial culture?
Yes, a pure culture refers to a microorganism culture that contains only a single strain or species, free from contamination. Microbial culture is a broader term that can refer to any type of culture of microorganisms, including pure cultures or mixed cultures containing multiple strains or species.
How would you define pure culture sterile and contamination in the isolation and purification of bacteria?
A pure culture is defined as a population containing only a single species or strain of bacteria. Contamination means that more than one species is present in a culture that is supposed to be pure.

What is the difference between pure culture and auxanic culture?
A pure culture contains only one type of microorganism, while an auxanic culture is a type of pure culture that has been enriched to promote growth of specific microorganisms, typically for research purposes. Auxanic cultures may contain growth factors or nutrients that allow the targeted microorganism to thrive.
Could you distinguish between axenic culture and pure culture?
An axenic culture refers to a culture containing only one species of microorganism without any other contaminants present. A pure culture, on the other hand, refers to a culture containing only one specific strain or species of microorganism, but it may still have contaminants present. In essence, axenic culture is free of any contaminants, while a pure culture may have contaminants other than the desired microorganism.
What is the difference between 100 whey protein and pure whey isolate?
whey protein(concentrate or 100%) contains usually between 70 to 80% protein while isolate 90% or more....

What is the purpose of quadrant streaking in bacterial cultivation?
Quadrant streaking is used to obtain isolated colonies of bacteria by diluting a starting culture across sections of an agar plate. This technique helps to separate individual bacterial colonies for further analysis, such as identifying different species, studying colony morphology, or performing antibiotic susceptibility testing.
Which culture medium preparation is most commonly utilized in isolation of pure culture?
Solid media is used for the isolation of bacteria as pure culture. 'Agar' is most commonly used to prepare solid media.
