Nt= N0e^rt
Nt= number of cells after time t,
t= time
r= growth rate
here
N0= 500
t= 2 hours= 2
60=120
minutes
r= 0.049 per minute
Nt= 500
e^(120
0.049)
=178904.6 cells
number of cells after 2 hours= 178904.6 cells

Example An otherwise typical bacterial cell increases from one cell to 256 cells in 10 hours. What is the generation time of this organism? Example: Escherichia coli has a doubling time of 20 minutes. If there are 5 cells at the beginning of the experiment, how many will there be in 3 hours? Example You perform a serial dilution and determine that the original number of cells in your sample was 12,000. How many bacteria will be present in 12...

The bacteria you are using grow with a generation time of 18 minutes in the medium that you are using. You inoculate the flask of medium with 8.00×104 bacteria. The flask is incubated for 180 minutes. Assume there is no lag phase and the culture does not reach stationary phase during the period of incubation. Within 5%, what is final number of bacteria in the flask? (Do not use scientific notation to enter your answer. Enter 4.2 x 107 as...

MICROBIO HELP: You want to grow up some bacteria to bring to class to show your friends, and you want to have enough to give everyone in the class 100 bacteria. If you are starting with only 5, how many generation times should you allow so you will have enough? (assume there are 130people in the class). If you knew it took 1 hour and 39 minutes to grow all your bacteria, what is the generation time? Helpful information provided:...
