6. If there were 45 bacterial colonies on Plate D, how many organisms were in 1 ml of the original sample? 45 x (1/1 mL) x 1/10^-7 = 4.5 x 10^8 From the information provided in the dilution scheme below, give the dilution factors of: Bottle II: Tube III: Tube V: Plate A: Plate B: Plate C:

a) If you counted 79 colonies on your 10^-4 plate with an inoculum of 0.1 mL taken from your 10^-4 dilution, what were the original CFU/mL? b) If you counted 123 colonies on your 10^-6 plate with an inoculum of 1.0 mL taken from your 10^-6 dilution, what were the original CFU/mL? c) Assume that 0.01 mL of a 10^-3 dilution was plated and you counted 87 CFU from that plate. What would be the concentration (in CFU/mL) of the original bacterial culture?
