The streak plate method makes it easier for colonies of bacteria to grow. It also generally leads to individual colonies that look like small dots, rather then simply a mat of bacterial growth.
Streak plating allows for the formation of individual colony forming units for isolation by reducing the number of bacterial cells with each streaked quadrant.
Advantages: 1. Counts only living cells 2. Standardized test - used worldwide Disadvantages: 1. 1-2 days of incubation 2. Melted, heated agar 3. Osmotic shock
The purpose of making a streak plate is to isolate a single colony of bacteria on an auger filled petri dish. You may need to culture this colony for a later experiment. A colony is created after a...
In the pour plate, the microorganisms will grow within the gel that has been set, and in the spread-plate technique, growth will be on top of the agar gel where it has been spread.
