Answer / guest
CFU/ML is CFU per milli-litre.
CFU stands for "Colony Forming Unit".
It depends on three things:
1) How many bacteria colonies do you observe? Count them.
2) How much milk sample do you take to culture?
3) What is your dilution factor?
Say, if you have 100 colonies and you use 0.1ml and your
dilution factor is 10^-2
Your CFU/ml would be (100/0.1) x 10^2

In microbiology, colony-forming unit (CFU or cfu) is a
measure of viable bacterial or fungal numbers. Unlike direct
microscopic counts where all cells, dead and living, are
counted, CFU measures viable cells. For convenience the
results are given as CFU/mL (colony-forming units per
milliliter) for liquids, and CFU/g (colony-forming units per
gram) for solids.

Answer / ramya seran
* Colony Forming Unit
* This is the count of isolated colonies on the plate
* CFU is a measure of viable cells in numbers
* Colony forming units may be reported as CFU per unit weight, CFU per unit area, or CFU per unit volume depending on the type of sample tested.
* CFU is not a measure for individual cells or spores as a colony may be formed from a single or a mass of cells or spores.
