A halophilic, aerobic mesophile has a generation time of 20 minutes. You place 1 × 104 of these organisms on an appropriate solid medium, and incubate the plate for 100 minutes. Select the FALSE statement.

Question

Quizplus · Accepted Answer

According to the given data, the generation time of the organism is 20 minutes. Therefore, after 100 minutes of incubation, there will be (100/20) = 5 generations of growth. Starting with 1 × 104 cells, this would result in a final population size of 32 × 104 or 3.2 × 105 cells. The statement in option C is true. Option A states that the growth medium contains NaCl, which is consistent with the organism being halophilic (salt-tolerant). Option B states that the organism will grow at 40oC, but there is no information provided in the question about the temperature range for growth. Option E states that the organism produces superoxide dismutase and catalase, which are common enzymes produced by many aerobic bacteria to detoxify oxygen radicals.
