- Question 5 You spread a small amount of a water sample from the environment on an enriched media agar plate. After 24 hours, the plate is covered with many small yellow colonies. Does this plate contain a pure culture of bacteria? ○ No, because it came from the environment, there are lots of different organisms. ○ We know there are multiple species present, but each colony is a different species. ○ Yes, we know the plate contains a pure culture because there are individual colonies. ○ We do not know if the plate contains a pure culture or a mixed culture. or even if individual colonies are pure or mixed based on their appearance alone.Question 6 Which of the following is the correct sequence for the aseptic transfer of a bacterial culture? - 1. 2. 3. 4. 5. 6. 7.
