Given a log phase bacterial culture with 1 x 10^6 cells per ml and a generation time of 30 minutes how long does it take the culture to reach a density of 6.4 x 10^7 cells per ml?
Why would cells that are vigorously growing when inoculated into fresh culture medium have a shorter lag phase than those that have been stored in a refrigerator?
Assume an inoculum with a cell density of 108 cells per mL. The entire generation time takes 30 minutes. How many hours would it take to grow a culture to 108/mL if you started with a 10–2 dilution?
helpful formula:
g (generation time) = 0.301 (time)/ log x – log xo
