In which of the following growth phases does the number of bacteria increase most rapidly?
Correct answer: B. Log phase
- A. Lag phase
- B. Log phase
- C. Stationary phase
- D. Death/Decline phase
Explanation
The exponential or the log phase is the phase during which the bacterium increases the most rapidly. In the figure below, the x-axis represents time and the y-axis represents log of the number of bacteria. Hence, the slope of the graph is directly proportional to the rate of multiplication of bacteria; the exponential phase has the greatest rate of multiplication of bacteria due to having the greatest slope.
