Quizplus · Accepted Answer

Pure cultures can be obtained using any of the three methods: streak plates, agar dilution method, or liquid dilution method. The choice of method will depend on the specific organism and the resources available. Streak plates are often used for isolating bacteria from mixed cultures, the agar dilution method is useful for determining the minimum inhibitory concentration of antibiotics, and liquid dilution methods are useful for isolating microorganisms that grow poorly on solid media or for studying microbial interactions in liquid cultures.
