Why is dilutions a necessary part of pure culture preparation?
Dilutions are necessary in pure culture preparation to achieve accurate and reproducible results. By diluting the original sample, it helps ensure that the cells are spread out evenly on the agar plate, allowing for the isolation of individual colonies. This helps in determining the concentration of the original sample and allows for better counting and identification of specific microbial species.
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
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.
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.
What is a bacterial culture containing a single species of organisms referred to as?
A bacterial culture containing a single species of organisms is referred to as a pure culture. This means that there is only one type of bacteria present in that culture without any contamination from other species. Pure cultures are essential for studying specific bacterial characteristics and behavior.
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.
What is the importance of developing pure microbial culture?
This is important in order to classify, characterize and diagnose the disease the culture may cause. This will help in staining, and also further the identification and specification of the bactera.
Is river water pure after its been sieved and why?
No, it is not necessarily pure after being sieved. This will not remove any microbial matter.

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
Why obtain pure culture of bacteria from a mixed culture?

What is axenic culture?
Axenic culture refers to the growth of pure microbial cultures devoid of any other contaminating organisms. This is achieved by using sterile techniques and media to ensure that only the desired microorganism can grow. Axenic cultures are important for studying the characteristics and behavior of specific microorganisms without interference from other organisms.
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 meaning of sudha?
Amrit, an ambrosia or drink that bestows immortality (Hindu mythology); immortality
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.
How would you define pure culture and 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.
