Calculation of Microbial Populations Jack inoculated a broth culture with 12 bacterial cells. After 12 days the culture contained 49,152 bacteria. How many generations had occurred and what was the generation time in hours for this particular bacterium. A new intestinal isolate of E. coli is known to have a generation time of 12 minutes. If a culture contained 3, 221,225,472 bacterial cells after 6 hrs how many bacteria must have been inoculated into the culture at time 0. A...

An exponentially growing culture has a specific growth rate constant, K = 2.4 day-1. What is the generation time? A test tube of fresh medium is inoculated with initial cell population of 6 x 105 cells/mL. Assuming no lag time, how long will it take for the culture to reach 8 x 109 cells/mL.

A bacterial population with a generation time of one hour will double in size every hour. This means that if a culture is inoculated with a single newly formed cell at 0.0 hours, the population would be expected to be composed of two cells at 1.0 hour, four cells at 2.0 hours, eight cells at 3.0 hours, etc. Calculate the number of bacterial cells in the population at every hour from 0.0 to 13.0 hours.
