Four sterile broth media were inoculated with four different bacterial cultures (A, B, C, and D). The same amount of bacterial culture was added to each of the four tubes. The tubes were then incubated at 37˚C for 24 hours. After 24 hours, the same volume of bacterial culture was taken from each of the tubes and plated onto four separate agar plates and incubated for 24 hours. Analyze the four plates and select which organism has the shortest generation time? Explain on what basis did you make the selection? You will not receive any points if your explanation is incorrect.
