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.
What is the main advantage of T-streak?
The main advantage of T- streak method: 1. To get a very good isolated colonies.2. To obtain pure culture from mixed culture.
Why is it to obtain to maintain a pure culture?
control the contamination
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.
Why is it necessary to use a solid agar medium to obtain a pure culture of S. epidermidis?
It is not a rule that it is done always this way. However, the sample you take is from the skin and it is going to be mixed with many other bacteria types. Using an agar plate and proper techniques, you can easily separate it from the others.
What is the purpose of quadrant streaking in bacterial cultivation?
The purpose is to isolate a pure culture of bacteria from a mixed culture of bacteria.
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.

How do you decide which colonies should be picked from a plate culture of mixed flora?
To decide on which colonies you should pick from a plate culture, you'll have to know whether you desire to grow a mixed culture of different microbes and bacteria or a pure culture that consists of only one strain of bacteria or microbe.
What are the prevention pure culture contamination?
if contamination is noted in a subculture sample, what should be to obtain a pure culture

How would you define pure culture sterile culture and contamination in the culture and isolation of bacteria?
A pure culture contains only one bacteria and no other. A sterile culture has only one bacteria in it and is usually used for transport. Contamination is something that doesn't belong. It can even be a small bit of plastic or wire. It is the opposite of a pure culture. The whole idea when working with isolating bacteria is to figure out which bacteria (or microbe) is causing an infection or disease in a patient. Your job is to help to figure this out so that the proper treatment can be started as soon as possible.
