Answer:
5.0 x CFU/mL
Explanation:
The dilution factor for a 1:1,000 dilution is .
Since 1 mL of the dilution was taken, the dilution factor that yielded the colony is /1 =
In order to find the colony forming unit (CFU) per volume (1 mL) of the original culture, divide the number of colony resulting from the plating of 1 mL of the dilution by the dilution factor. Hence;
CFU/mL of the original culture = 50/
= 5.0 x
Therefore, the concentration of the original culture is 5.0 x CFU/mL.
