An environmental (soil) sample obtained from a temperate region was transferred to a liquid growth medium and incubated at 30°C for 24 hours, then transferred to solid growth medium in order to isolate bacteria from the original sample. Following 48 hour incubation at 30°C, the picture of the solid medium shows the results of this experiment. Which of the following statement(s) among A D are true regarding this experiment? A. This plate represents a pure cultu B Isolates A and B are likely the only bacterial types that would have been present in the original environmental sample. A and B are probably the same microorganism D.
