3. You inoculate 1 liter of medium with an E. coli
culture to an initial cell density of 104 cells/ml. The culture
grows exponentially with a generation time of 20 minutes. What is
the culture density after 24 hours?

You inoculate a strain of E. coli into a broth culture and allow it to grow. The broth medium contains three sugars: glucose, lactose, and maltose. The strain you are growing prefers lactose to maltose. You measured the growth by doing a viable cell count and drew a growth curve after calculating the number of CFU/ml over time. There was an initial lag phase, followed by an exponential phase. There was a second lag phase of approximately 30 minutes followed...

Consider a culture of E. coli growing in exponential phase with a generation time of 20 minutes. Beginning with 2 x 106 cells per ml, how long will it take the culture to reach a density of about 3.2 x 107 cells per ml?

a) During the exponential phase of bacterial growth, the lab strain of E. coli has doubling time of about 30 minutes. If you start with 10,000 cells per mL of culture, and let them grow exponentially 2 hours in a flask, what is the final density of the culture? Show and explain your calculations. b) If you plated a100μL of 1:1000 dilution that culture (after it had grown in a flask for 2 hrs) how many colonies would you expect...

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.

E. Coli has a doubling time of 20 minutes under certain growth conditions. Compute the biomass of E. coli (in pounds) that will accumulate when a single cell of E. coli grows exponentially for 50 hours in these conditions, assuming that nutrients are not limiting. Show your work. (An E. Coli cell has a mass of 10-12gram/cell).

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...
