Suppose someone starts a broth culture of E. coli at an initial concentration of 5,000 cfu/mL. Suppose they mix 2 mL of culture with 8 mL of sterile saline. What dilution of the bacterial culture have they prepared? Now mix 2 mL of the dilution with 8 additional milliliters of sterile saline. What dilution of the dilution have they created? What is the total dilution of the original bacterial culture in the final tube?

To dilute a bacterial culture, 100 µL of a starter culture is mixed with fresh culture media to a final volume of 5 mL. The starter culture was diluted by a factor of? Given a bacterial culture with a concentration of 5x10^6 CFU/mL, how many cells are transferred when 10 μL of the culture are used to inoculate 500 mL of fresh media. Given a culture with a concentration of 8x10^9 CFU/mL, how many cells are transferred when 500 μL of the culture are used to inoculate 100 mL of fresh media. You've diluted 100 µL of sample with 300 µL of distilled water for a 1:4 dilution. You then take 100 µL of the 1:4 dilution and add 100 µL of distilled water. What number do you need to multiply your result by?
