WebAdvantages of the Streak Plate Method. It is one of the most popular techniques used to obtain isolated colonies of bacteria. It finds a great application in biotechnology as it can … In microbiology, streaking is a technique used to isolate a pure strain from a single species of microorganism, often bacteria. Samples can then be taken from the resulting colonies and a microbiological culture can be grown on a new plate so that the organism can be identified, studied, or tested. The modern streak plate method has progressed from the efforts of Robert Koch and …

WebStreaking is the process of isolating single colonies of an organism on an agar plate 2 , therefore what we expected to observe was isolated, single colonies of our culture in the fourth quadrant. The microorganisms seemed to become more isolated after each quadrant on the agar plate, which can be observed in Figure 2, therefore is what was expected. WebBacterial isolation is defined as the technique of separating one species of bacteria from the bacteria’s mixed culture by different plating methods like pouring, spreading, streaking, and serial dilution. The growth of bacteria can be observed over the solid nutrient medium, in the liquid broth medium and some automated liquid culture medium.
