One fail safe way to obtain a pure culture is the streak plate method. This is the best of several ways to obtain a PC. Streak plates allow us to isolate a particular microbe from a mixed culture. A small amount of desired microbe is obtained with a sterile loop, and a single colony is grown on a separate quadrant of the agar plate, or ideally another agar plate all together. One advantage to this method is that a skilled student can, if experienced and skilled, recolonize one particular type of bacteria/microbe up to three times on one agar plate, wherefore less materials are used. Another significant benefit is that this is one of the quickest methods.
Another method of obtaining a pure culture is the pour plate method. Pour plating is a method of separating one species of bacteria from another by diluting one loopful of organism into three liquefied nutrient agar plates, with the hopes that one of the plates poured will provide an ideal sample for isolation. An advantage to this method is that it requires far less skill than the first method, however requires far more materials and time.

Describe the methods that you can use to obtain a pure culture and state the significance?
A pure culture is usually derived from a mixed culture (one containing many species) by transferring a small sample into new, sterile growth medium in such a manner as to disperse the individual cells across the medium surface or by thinning the sample manyfold before inoculating the new medium. Both methods separate the individual cells so that, when they multiply, each will form a discrete colony, which may then be used to inoculate more medium, with the assurance that only one type of organism will be present
The important of obtain pure bacteria?
The need of pure culture of bacteria to characterize an individual species. Pure culture are also important to study the morphology and physiology of individual bacterial species, their biochemical behaviour and response to different compounds like antibiotics, which all can me alter by the influence of other species if prestent (in mixed culture) and also for isolating and studying of their molicular structure i.e. DNA or RNA. Some common ways to obtain a pure culture of bacteria are: 1 The spread plate technique. 2 The pour plate. 3 Streak plate technique.
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.
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.
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
What are the methods to obtain pure nicotine?
There are several methods to extracting and or obtaining pure nicotine. Many times you can extract the nicotine with normal house hold chenicals and products. Nicotine is a very hazardous material and handling of raw or pure nicotine is very hazardous. Make sure you read all information carefully before trying the extraction.

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.
