A loopful of bacteria containing 1000 bacterial cells is inoculated into a nutrient broth and incubated.After a negligible lag phase, the culture goes into exponential growth for two hours.The generation time for the bacterium is fifteen minutes.Which equation is the correct one to determine the number of cells present after two hours of log phase growth?

Question

Quizplus · Accepted Answer

The correct equation to determine the number of cells present after two hours of log phase growth is 1000 X 2⁸. This is because the generation time for the bacterium is fifteen minutes, and two hours is equal to eight generations. Therefore, the number of cells present after two hours of log phase growth will be 1000 X 2⁸ = 256,000 cells.
